Heat Teaches Balance

Infrared sauna benefits come from precision: heat, wavelength, sweat, and cooling teach the body to regulate mood, sleep, and recovery with more balance.

A grounded look at how infrared sauna protocols may support mood, sleep, detoxification, and recovery by working with heat, light, and the body's thermoregulation.

Heat, Mood, and the Depression Question

Infrared sauna is often spoken about as a single category, but the conversation begins with a more precise idea. Infrared is a spectrum of wavelengths, and different parts of that spectrum appear to interact with the body in different ways. That distinction matters because a protocol becomes more meaningful when you know what kind of heat and light you are asking the body to receive.

The episode points to a 2016 whole-body heating study led by Dr. Raison, which explored whether raising core temperature could influence depression. The equipment used was expensive and difficult to access, but the reported result was striking: one session produced a significant reduction in signs of depression among participants described as severely depressed. The relief was described as appearing within one week and lasting up to six weeks from that single exposure.

That finding does not turn sauna into a simple answer for depression. It does invite a more grounded question: what happens when the body is heated deliberately, slowly, and safely enough to shift its internal regulation. The value sits less in intensity and more in precision. Heat becomes a signal, not a test of endurance.

The newer research discussed in the episode moves toward accessibility. Dr. Mason, described as a protege of Dr. Raison, is studying a head-out chamber model that resembles a portable infrared sauna design. That matters because comfort changes adherence. When the head stays out and the body warms gradually, people can often remain in the session longer, giving the protocol time to work with core temperature rather than simply overwhelming the system.

The central idea is thermoregulation, the body's ability to rise, cool, and return to balance. In the episode, depression is discussed alongside disrupted temperature rhythms, especially a higher baseline temperature and difficulty cooling down at night. Infrared heat is framed as a way to help the body relearn that rhythm. You are not forcing a result; you are creating conditions for regulation to resume.

This is where sauna practice becomes more than passive warmth. A deliberate session can act like a regulatory ritual, asking the body to adapt without the mechanical strain of exercise. The aim is not to chase heat for its own sake. The aim is to support a return to equilibrium, where mood, sleep, and recovery have more room to organize.

foreign you're listening to the human upgrade you're listening to the human upgrade with Dave asprey with Dave asprey today as always I am going to tell you today as always I am going to tell you what you get at the start of the episode what you get at the start of the episode so you can say this episode is worth so you can say this episode is worth your time in fact it's way more than your time in fact it's way more than worth your time otherwise you shouldn't worth your time otherwise you shouldn't do it do it we're going to go deep in the world of we're going to go deep in the world of biohacking on infrared light and biohacking on infrared light and infrared heat we're going to talk about infrared heat we're going to talk about infrared light affects your body how it infrared light affects your body how it triggers a bunch of different triggers a bunch of different biochemical Cascades we're just figuring biochemical Cascades we're just figuring some of this out some of this we've some of this out some of this we've known about at some levels but now known about at some levels but now because there's so many of us biohacking because there's so many of us biohacking in the world there's real University in the world there's real University Research happening it's becoming its own Research happening it's becoming its own industry and industry and this means that we can now instead of this means that we can now instead of saying saying something good for you we can say this something good for you we can say this amount of this type is good for you and amount of this type is good for you and if you want an analogy imagine if I said if you want an analogy imagine if I said fat was good for you well if you're like fat was good for you well if you're like a keto bro you'd say yeah bro except I

01:00

a keto bro you'd say yeah bro except I didn't say what kind of fat so some fats didn't say what kind of fat so some fats are good and some are bad so now if we are good and some are bad so now if we say infrared is good for you well which say infrared is good for you well which kind of infrared does what and that's kind of infrared does what and that's we're going to learn in this episode we're going to learn in this episode and as you know and as you know I bring experts in a field people have I bring experts in a field people have done a lot of work on the show and done a lot of work on the show and that's the minimum minimum bar I like that's the minimum minimum bar I like Connie because she always knows all the Connie because she always knows all the weird details about infrared and because weird details about infrared and because she's built it from the ground up she's built it from the ground up herself over 22 years along with her herself over 22 years along with her husband so these this is a leader in the husband so these this is a leader in the industry of infrared therapy industry of infrared therapy so welcome to the show again so welcome to the show again thank you so much Dave it's so good to thank you so much Dave it's so good to see you see you we've already talked about infrared on we've already talked about infrared on the show so people may have heard you the show so people may have heard you they may have heard about sunlight and they may have heard about sunlight and so this episode has to include stuff so this episode has to include stuff that we don't know about so I want to go that we don't know about so I want to go into the area of depression because so into the area of depression because so many people are anxious they're many people are anxious they're depressed it's almost like we might have

02:00

depressed it's almost like we might have made a societal mistake over the past made a societal mistake over the past couple years that resulted in increased couple years that resulted in increased depression levels at least that's what depression levels at least that's what the data says so what do we know about the data says so what do we know about infrared and depression infrared and depression yeah so there's some Cutting Edge yeah so there's some Cutting Edge studies that are being done right now studies that are being done right now but first we'll take a but first we'll take a um like a backup to how a lot of this um like a backup to how a lot of this came came um to play which is back in 2016 Dr um to play which is back in 2016 Dr brazon did a study trying to figure out brazon did a study trying to figure out what is causing people to be depressed what is causing people to be depressed and had some theories and found that he and had some theories and found that he used a um it's very expensive piece of used a um it's very expensive piece of equipment to do whole body hypothermia equipment to do whole body hypothermia which is heating the body up over which is heating the body up over extended periods of time extended periods of time um and elevating the core temperature um and elevating the core temperature and in what he found which is just still and in what he found which is just still every time I say it it blows my mind every time I say it it blows my mind because because in the amount of time one session

03:00

in the amount of time one session one session delivered one session delivered significant reduction in the signs of significant reduction in the signs of depression and keep in mind when he did depression and keep in mind when he did this study the the people that he chose this study the the people that he chose were that to qualify they were severely were that to qualify they were severely depressed so high high levels of depressed so high high levels of depression and with one session depression and with one session um he found that by increasing their um he found that by increasing their core temperature heating the body up core temperature heating the body up they that it elevated the temperature they that it elevated the temperature Three Degrees that they were able to Three Degrees that they were able to have significant relief in only one week have significant relief in only one week and then that lasted that one session and then that lasted that one session lasted for six weeks lasted for six weeks so that was the study in 2016. so that was the study in 2016. and then one of his proteges Dr Mason and then one of his proteges Dr Mason saw that study and the findings and saw that study and the findings and decided to take the concept of that decided to take the concept of that information and like reapply that and information and like reapply that and now she's doing her own studies in

04:00

now she's doing her own studies in California and she is what the great California and she is what the great thing about what she's doing is is she's thing about what she's doing is is she's doing it with a model that's very doing it with a model that's very similar to our sunlight and Zelda which similar to our sunlight and Zelda which is a portable chamber you know where is a portable chamber you know where your head is out because they found that your head is out because they found that when people are immersed into heat if when people are immersed into heat if they're too hot then it's not good right they're too hot then it's not good right so and they can't stay in very long and so and they can't stay in very long and the whole benefit of of infrared helping the whole benefit of of infrared helping with depression is being able to slowly with depression is being able to slowly increase the core temperature and being increase the core temperature and being able to be in there for a while and so able to be in there for a while and so Dr Mason is doing a study that is Dr Mason is doing a study that is already protocols have already been already protocols have already been approved with an accessible piece of approved with an accessible piece of equipment that people could use post equipment that people could use post results of the study and which is super results of the study and which is super exciting because the piece of equipment exciting because the piece of equipment that Dr rayson did was in Germany even that Dr rayson did was in Germany even number one number two it um costs fifty number one number two it um costs fifty thousand dollars so kind of cost thousand dollars so kind of cost prohibitive for people to apply back in prohibitive for people to apply back in the comfort of their own home years ago

05:00

the comfort of their own home years ago I radically changed my metabolism I radically changed my metabolism because I was cold all the time I had because I was cold all the time I had hypothyroid issues and I talked to an hypothyroid issues and I talked to an industrial control engineer who talked industrial control engineer who talked about set points for systems and he had about set points for systems and he had a protocol it was pretty extreme you a protocol it was pretty extreme you took higher than normal doses of thyroid took higher than normal doses of thyroid hormone you wore a jacket all the time hormone you wore a jacket all the time drink hot water all day long and sat in drink hot water all day long and sat in hot saunas for a week and you basically hot saunas for a week and you basically cooked yourself for a week as much as cooked yourself for a week as much as you could and when you were done your you could and when you were done your body temperature would rise because mine body temperature would rise because mine was instead of 98.6 I was about 96.8 and was instead of 98.6 I was about 96.8 and right now human body temperatures are right now human body temperatures are dropping and all sorts of bad stuff dropping and all sorts of bad stuff happens when you don't have the right happens when you don't have the right the right temperature but it was really the right temperature but it was really expensive and you had to go to Germany expensive and you had to go to Germany and I didn't have cancer the the the and I didn't have cancer the the the safest and healthiest way to get the safest and healthiest way to get the benefit of a rise in temperature like benefit of a rise in temperature like that would be an infrared setup like the that would be an infrared setup like the solo one that sunlight makes solo one that sunlight makes so if you don't have cancer which wasn't so if you don't have cancer which wasn't my concern I just wanted the biological my concern I just wanted the biological anti-aging benefits of this what's going

06:00

anti-aging benefits of this what's going to happen if you raise your body to happen if you raise your body temperature with the single person head temperature with the single person head out model that you make like give me a out model that you make like give me a bullet point list of effects but just bullet point list of effects but just want people to know this is a real thing want people to know this is a real thing it's been going on for 20 years this it's been going on for 20 years this isn't new it's just something you isn't new it's just something you haven't heard about haven't heard about exactly so the theory is that your a lot exactly so the theory is that your a lot of people and there's a lot of different of people and there's a lot of different conditions not just depression you know conditions not just depression you know you can talk about menopause you can you can talk about menopause you can talk about lots of different things talk about lots of different things where your body is unable to regulate where your body is unable to regulate itself so you know if you're itself so you know if you're depressed we know that people who would depressed we know that people who would have depression have higher base core have depression have higher base core temperatures and they are unable to cool temperatures and they are unable to cool themselves down so like at night their themselves down so like at night their body stays elevated with most people body stays elevated with most people their body cools its you know down well their body cools its you know down well sitting inside to answer your questions sitting inside to answer your questions sending inside or lying down and Silas sending inside or lying down and Silas for example is on light and Solo Sauna for example is on light and Solo Sauna chamber allows the body to kind of

07:00

chamber allows the body to kind of unlock that regulation that's locked unlock that regulation that's locked right so it like opens it up and turns right so it like opens it up and turns on the switch that now the body says oh on the switch that now the body says oh I didn't realize that I was supposed to I didn't realize that I was supposed to regulate and so now you go up so we so regulate and so now you go up so we so we know for sure we did a study forever we know for sure we did a study forever ago which now that all the science is ago which now that all the science is coming out is so interesting because coming out is so interesting because we're able to connect the dots between we're able to connect the dots between our studies and the our studies and the um the other studies that are being done um the other studies that are being done we did a study measuring the body's core we did a study measuring the body's core temperature and how much can we increase temperature and how much can we increase your body's core temperature in 30 your body's core temperature in 30 minutes and we were able to increase the minutes and we were able to increase the body's poor temperature in 30 minutes body's poor temperature in 30 minutes that's something we did 20 years ago that's something we did 20 years ago Dave yep but now we're able to say okay Dave yep but now we're able to say okay so we know we can do that what does it so we know we can do that what does it do what's the mechanism of actual what do what's the mechanism of actual what does it do to the body and what are the does it do to the body and what are the effects and the facts are that when effects and the facts are that when you're able to do that then now you're you're able to do that then now you're going to regulate the the temperature in going to regulate the the temperature in the body so the body is going to allow the body so the body is going to allow itself to cool down so now itself to cool down so now now the people who are suffering from now the people who are suffering from depression their brain goes oh oh thank

08:00

depression their brain goes oh oh thank God like I'm cooler now my body's going God like I'm cooler now my body's going to be able to raise up cool down raised to be able to raise up cool down raised up cool down so self-regulation works up cool down so self-regulation works better it's like a form of exercise we better it's like a form of exercise we know there are tools to time so if you know if you're on medication you know it can take medication you know it can take medications a long time to make an medications a long time to make an impact on your body to relieve but this impact on your body to relieve but this happens happens yeah for depression specifically yeah yeah for depression specifically yeah because then it goes to the other impact because then it goes to the other impact is is people who have high temperatures at people who have high temperatures at night don't sleep as well right so now night don't sleep as well right so now you know they can have a better night's you know they can have a better night's sleep and it's hard to sleep well if sleep and it's hard to sleep well if you're hot but um don't you make saunas you're hot but um don't you make saunas that make you hot that make you hot yes yes [Music] it leaves the question though because if I use my sunlighten yes before bed I see

09:00

I use my sunlighten yes before bed I see an improvement in deep Sleep usually not an improvement in deep Sleep usually not a decrease in deep Sleep what's going on a decrease in deep Sleep what's going on there correct well because it you're there correct well because it you're you're again you're unlocking the you're again you're unlocking the thermoregulation like so you're you're thermoregulation like so you're you're helping your body to Thermal regulate helping your body to Thermal regulate you're also getting your body you know you're also getting your body you know into a into a like rhythm of okay now like this is like rhythm of okay now like this is what I my brain knows I'm doing this to what I my brain knows I'm doing this to unwind I'm getting ready to you know unwind I'm getting ready to you know pair my body I'm getting plus you're pair my body I'm getting plus you're you're detoxing so let's talk about that you're detoxing so let's talk about that for a second so you're you're sweating for a second so you're you're sweating and you're removing and you're removing um potentially a toxic load heavy stuff um potentially a toxic load heavy stuff that's inside your body when that comes that's inside your body when that comes out that's going to also you know out that's going to also you know lighten the load lighten and then also lighten the load lighten and then also help with the brain you feel more energy help with the brain you feel more energy um as a result not an energy I like to um as a result not an energy I like to go like you know like you know to not be go like you know like you know to not be able to sleep by any means but an energy

10:00

able to sleep by any means but an energy to say okay to say okay like you know I feel purged I feel like you know I feel purged I feel cleansed cleansed um and then you do need a little bit of um and then you do need a little bit of time I don't know do you go directly I time I don't know do you go directly I don't go directly to sleep you do need a don't go directly to sleep you do need a little bit of time in between little bit of time in between if you do it at night you're sauna if you do it at night you're sauna session and sleep how do you do it I'm session and sleep how do you do it I'm kind of a mutant I guess I can get out kind of a mutant I guess I can get out of the sauna rinse off in the shower and of the sauna rinse off in the shower and go right to sleep but go right to sleep but I think it works because of exclusion I think it works because of exclusion Zone water and one of the things we Zone water and one of the things we haven't talked about yet is that haven't talked about yet is that infrared when it hits the water in your infrared when it hits the water in your cells I think you mentioned the very cells I think you mentioned the very beginning briefly it changes the beginning briefly it changes the viscosity viscosity of the water so the water works better of the water so the water works better for making energy and I've published a for making energy and I've published a couple studies and probably headstrong couple studies and probably headstrong my book about cognitive function about my book about cognitive function about how having better mitochondrial function

11:00

how having better mitochondrial function equals better sleep quality because equals better sleep quality because mitochondria power the glymphatic system mitochondria power the glymphatic system that washes out your brain so you've got that washes out your brain so you've got dropping toxins directly in the sauna dropping toxins directly in the sauna because they came out through the skin because they came out through the skin and then you've got water that works and then you've got water that works better for making ATP that's left inside better for making ATP that's left inside the body so when you go to sleep that's the body so when you go to sleep that's probably better than being hot probably better than being hot and the shower I take is not a cold and the shower I take is not a cold shower but it's not a very hot shower shower but it's not a very hot shower either so that may help to return me to either so that may help to return me to normal temperature so that's a normal temperature so that's a possibility yeah no no talked to um Dr Michael Hamblin about who has um Dr Michael Hamblin about who has become a medical advisor for sunlight become a medical advisor for sunlight and has really helped us to and has really helped us to to to understand all this new science and and understand all this new science and and um and he is you know informed us that um and he is you know informed us that the way infrared is being received if the way infrared is being received if you kind of look at infrared as being you kind of look at infrared as being the quarterback and you look at the

12:00

the quarterback and you look at the different parts of the infrared Spectrum different parts of the infrared Spectrum the near Mid and far as receivers each the near Mid and far as receivers each receiver has a different role receiver has a different role and takes the wavelength and makes the and takes the wavelength and makes the changes to your body and so with the changes to your body and so with the easy water the exclusion Zone absolutely easy water the exclusion Zone absolutely like the infrared is being thrown it's like the infrared is being thrown it's being absorbed you know by the being absorbed you know by the mitochondria and then that is converted mitochondria and then that is converted to re um story more energy and giving to re um story more energy and giving you a definitely like helping you to you a definitely like helping you to sleep better sleep better helping your cells be stronger helping helping your cells be stronger helping your immune system your immune system there's a lot I mean the the list of there's a lot I mean the the list of benefits benefits it has always been crazy what I love now it has always been crazy what I love now is I can now go to certain elements is I can now go to certain elements right like I can go to easy water or I right like I can go to easy water or I can go to depression studies or I can go can go to depression studies or I can go to some of the cardiovascular and I can to some of the cardiovascular and I can go to these elements and say okay so go to these elements and say okay so this is why this is why I feel like you know I can have so much

13:00

I feel like you know I can have so much more energy it's very interesting to me more energy it's very interesting to me that I always have been saying forever that I always have been saying forever for 22 years after I use my sunlight and for 22 years after I use my sunlight and sauna I I am not drained and intuitively sauna I I am not drained and intuitively with you know when I started like the with you know when I started like the only saunas that were available were the only saunas that were available were the hot Roxanna right and people would hot Roxanna right and people would always say I don't like especially always say I don't like especially females would females would um call and they were like I don't want um call and they were like I don't want to feel drained I don't want to feel to feel drained I don't want to feel like I'm exhausted after I get done like like I'm exhausted after I get done like I don't want to go through that I don't want to go through that experience like well it's not like that experience like well it's not like that with infrared you don't you don't feel with infrared you don't you don't feel exhausted you don't feel drained you exhausted you don't feel drained you actually feel more energetic actually feel more energetic and a more restored and now with like and a more restored and now with like the easy Zone and with some of the the the easy Zone and with some of the the depressed like the thermoregulation a depressed like the thermoregulation a lot of these mechanism of actions were lot of these mechanism of actions were understanding better about how infrared understanding better about how infrared works and The receptors and the works and The receptors and the different parts of the spectrum now it different parts of the spectrum now it makes sense why I feel so much more makes sense why I feel so much more energetic after I use a Asana

14:00

energetic after I use a Asana and imprints on us specifically and imprints on us specifically let's talk about this I'm getting let's talk about this I'm getting comments from the upgrade Collective comments from the upgrade Collective half of them are saying I get energized half of them are saying I get energized when I do my Emperor sauna and others when I do my Emperor sauna and others are saying a one I get knocked out after are saying a one I get knocked out after 10 minutes I know that if I stand for 45 10 minutes I know that if I stand for 45 minutes to an hour that I start to get minutes to an hour that I start to get sleepy is there a length of time that's sleepy is there a length of time that's energizing versus sleepy there's not a Amazon when you're using an infrared sauna when you're using an infrared sauna there's three different parts of the there's three different parts of the infrared infrared spectrum and there the what makes spectrum and there the what makes enlightened special is we were able to enlightened special is we were able to capture near infrared with LEDs mid capture near infrared with LEDs mid infrared with a specific heating element infrared with a specific heating element and then Farm Fred's separate one so and then Farm Fred's separate one so you're getting all three ones you're getting all three ones um and each wavelength responds your

15:00

um and each wavelength responds your body responds differently to that and body responds differently to that and sometimes like for example in the near sometimes like for example in the near infrared the way it works with the infrared the way it works with the mitochondria that's that's the energetic mitochondria that's that's the energetic so if you're getting a lot of near so if you're getting a lot of near infrared you probably will have be infrared you probably will have be more energetic than sleepy there's this more energetic than sleepy there's this this beautiful band of light that is the this beautiful band of light that is the light from the sun without the harmful light from the sun without the harmful rays but within that band there's three rays but within that band there's three separate categories in each category has separate categories in each category has its own receptors in its own benefits so its own receptors in its own benefits so depending on how your receptors respond depending on how your receptors respond to near-infrared Mid or far and to near-infrared Mid or far and depending on the type of infrared sauna depending on the type of infrared sauna you are using you're going to have you you are using you're going to have you know a little bit of different know a little bit of different experience experience it's it's interesting you could mix all it's it's interesting you could mix all three of these things but you wouldn't three of these things but you wouldn't see any difference at all right how see any difference at all right how would people know if they're not getting

16:00

would people know if they're not getting a sunlight and a sunlight and whether they're getting a specific part whether they're getting a specific part of those wavelengths because most time of those wavelengths because most time it just says either infrared sauna or it just says either infrared sauna or Farm Infrareds on it when you're buying Farm Infrareds on it when you're buying something that's a generic white label something that's a generic white label sort of thing yeah that's a great sort of thing yeah that's a great question question most infrared saunas are most infrared saunas are usually in the mid category based on usually in the mid category based on this it's so I'm going to go deep here this it's so I'm going to go deep here for just a second on science so what for just a second on science so what defines defines the wavelength is the surface the wavelength is the surface temperature of the heater and most temperature of the heater and most Infrareds on a surface temperature not Infrareds on a surface temperature not the air temperature I'm talking about if the air temperature I'm talking about if you were to put your hand up next to the you were to put your hand up next to the heater the surface temperature most of heater the surface temperature most of them are not as cool and and do not them are not as cool and and do not definitely have all three wavelengths as definitely have all three wavelengths as sunlight and does because we have the sunlight and does because we have the patent on two or more separate patent on two or more separate wavelengths so there can be some that wavelengths so there can be some that have two but there isn't well I know we have two but there isn't well I know we have a patent on two or more so most are

17:00

have a patent on two or more so most are Just One Singular wavelength and then Just One Singular wavelength and then within that wavelength it's usually within that wavelength it's usually within the far to Mid category within the far to Mid category what's going on is we know now the what's going on is we know now the biology knowledge we know the physical biology knowledge we know the physical knowledge we're putting those two knowledge we're putting those two together you took it but talk to me together you took it but talk to me about what the the range of infrared about what the the range of infrared that actually absorbs in water is and that actually absorbs in water is and why you chose a very specific number why you chose a very specific number yeah so the yeah so the um Range As We Know um Range As We Know for that transforms the body is between for that transforms the body is between near and mid infrared so in that range near and mid infrared so in that range so so near just to be more specific is so so near just to be more specific is about you know seven about you know seven nanometers ish and when I say near it is nanometers ish and when I say near it is invisible light so there is also some invisible light so there is also some colored lights that are of a different

18:00

colored lights that are of a different wavelength near is invisible and the wavelength near is invisible and the right way to receive near to get the right way to receive near to get the maximum absorption into the body is via maximum absorption into the body is via LEDs not via heat because you can't it LEDs not via heat because you can't it would be excessively hot and you would would be excessively hot and you would get such a small small amount basically get such a small small amount basically it would be like the filament of a light it would be like the filament of a light bulb if um if you were to sit inside a bulb if um if you were to sit inside a quote unquote like just near infrared if quote unquote like just near infrared if there was any heat it's LEDs can deliver there was any heat it's LEDs can deliver and we've chose we worked back when we and we've chose we worked back when we developed developed impulse gosh back I don't know in 2008 impulse gosh back I don't know in 2008 so 14 years ago we worked with some so 14 years ago we worked with some experts experts um in Minnesota and Wisconsin and out um in Minnesota and Wisconsin and out east MIT to help us figure out the right east MIT to help us figure out the right nanometers and the right units and nanometers and the right units and measurements now as science is evolving measurements now as science is evolving we thought it was really just in the we thought it was really just in the near and Freight category but you're near and Freight category but you're actually even a little bit of the mid actually even a little bit of the mid you can get you can get um it your receptors in the body can

19:00

um it your receptors in the body can respond and make the Transformations respond and make the Transformations that we're talking about as far as into that we're talking about as far as into the exclusion zone so far is a totally the exclusion zone so far is a totally different like totally different the way different like totally different the way it receives the way the body responds it receives the way the body responds farm for red farm for red which is how we started back in in the which is how we started back in in the basement uh is it comes into the body basement uh is it comes into the body and it's absorbed it actually doesn't and it's absorbed it actually doesn't penetrate as deep as near infrared it's penetrate as deep as near infrared it's but it it's deep as far as the but it it's deep as far as the absorption into the water molecules and absorption into the water molecules and the water molecules those are the the water molecules those are the receptors of far they vibrate they receptors of far they vibrate they resonate they move and that's where resonate they move and that's where you've got a lot of the you've got a lot of the um exercising of the immune system um exercising of the immune system that's where you get the detox benefits that's where you get the detox benefits because you're changing the water because you're changing the water molecules and you're releasing the the molecules and you're releasing the the toxic burden through sweat that's very toxic burden through sweat that's very far so far infrared does detox near far so far infrared does detox near infrared does what energy and skin

infrared does what energy and skin Rejuvenation anti-aging and then Rejuvenation anti-aging and then infrared is pain infrared is pain pain okay so depending on which one you pain okay so depending on which one you pick you're going to get different pick you're going to get different results results and correct this is what I don't think and correct this is what I don't think people understand about infrared light people understand about infrared light if you were to go into the sunlight if you were to go into the sunlight which dose of which ones would you get which dose of which ones would you get well in sunlight but don't you get more of some you're getting the whole Spectrum but I'm getting the whole Spectrum but I'm guessing that there's a peak a peak guessing that there's a peak a peak amplitude where you're getting more amplitude where you're getting more mid-infrared probably do you know that mid-infrared probably do you know that off the top of your head it's kind of a off the top of your head it's kind of a weird question weird question I know that fifth greater than 50 I know that fifth greater than 50 percent of the Rays from the Sun have percent of the Rays from the Sun have the infrared Spectrum the infrared Spectrum and and the you receive and and the you receive more far infrared with cooler more far infrared with cooler temperatures and as you get closer to temperatures and as you get closer to Mid and near the temperatures are hotter

21:00

Mid and near the temperatures are hotter uh got it so uh got it so what's happening in the sun is that what's happening in the sun is that you're getting the full spectrum but you're getting the full spectrum but you're getting UVA UVB which will give you're getting UVA UVB which will give you a sunburn but they're actually you a sunburn but they're actually healthy for you to get a certain amount healthy for you to get a certain amount of that avoiding all of those is toxic of that avoiding all of those is toxic for you and then you get infrared which for you and then you get infrared which is one of the reasons you feel so good is one of the reasons you feel so good when you're in the sun right and then when you're in the sun right and then you get all the visible spectrum which you get all the visible spectrum which has its own signaling stuff in there and has its own signaling stuff in there and near infrared is the hottest part of the near infrared is the hottest part of the infrared Spectrum which is why I said infrared Spectrum which is why I said earlier it's really you have if you're earlier it's really you have if you're going to sit inside a sauna you have to going to sit inside a sauna you have to convert the heat into LEDs convert the heat into LEDs because it would be you couldn't because it would be you couldn't sit inside Asana with near-infrared heat sit inside Asana with near-infrared heat because it is so much hotter you can add because it is so much hotter you can add a very small amount of near infrared a very small amount of near infrared like using french fry bulbs is what most like using french fry bulbs is what most people do like the stuff that fast food

22:00

people do like the stuff that fast food restaurants used to have right you've restaurants used to have right you've seen it a little bit but it's not going seen it a little bit but it's not going to be a substantial dose and it's maybe to be a substantial dose and it's maybe beneficial even but what I don't think beneficial even but what I don't think you want to do is you wouldn't want to you want to do is you wouldn't want to do a near infrared only sauna in fact I do a near infrared only sauna in fact I don't think they even make those but don't think they even make those but right you want to be able to selectively right you want to be able to selectively and carefully mix the three types of and carefully mix the three types of infrared so that you get the effect infrared so that you get the effect you're looking for and that's why I've you're looking for and that's why I've been a big fan of your work because even been a big fan of your work because even going back 10 years ago you had a little going back 10 years ago you had a little tablet built in that says okay what did tablet built in that says okay what did you want to get out of your infrared you want to get out of your infrared session and based on that you've got a session and based on that you've got a little sunlight nap and say okay I want little sunlight nap and say okay I want to do one that's more cardiovascular to do one that's more cardiovascular stimulating or I want one that's more stimulating or I want one that's more detoxing and you're changing the recipe detoxing and you're changing the recipe for light and that's why this hard to for light and that's why this hard to explain but why I think the sunlight explain but why I think the sunlight approach is different than I sat there approach is different than I sat there and there was an emitter like no I have and there was an emitter like no I have digital control of an emitter so you can digital control of an emitter so you can pick a recipe or a prescription to get pick a recipe or a prescription to get radically different results right and

23:00

radically different results right and the other thing just to build on that the other thing just to build on that another thing we know for sure to help another thing we know for sure to help people who are listening is there is a people who are listening is there is a relationship between how close you are relationship between how close you are to the near LED so I don't know several to the near LED so I don't know several years ago we tripled the size I don't years ago we tripled the size I don't know if you remember this I've already know if you remember this I've already meters we made them super super large meters we made them super super large inside our impulse cabin so that people inside our impulse cabin so that people could literally put their their like I could literally put their their like I when I sit there I sit there with my when I sit there I sit there with my face right up next to the emitter or I face right up next to the emitter or I will do my knee or I will do like will do my knee or I will do like whatever I'm looking for to you know whatever I'm looking for to you know receive the near infrared because it receive the near infrared because it makes a huge difference how close you makes a huge difference how close you are to the emitter now are to the emitter now one of the things that I really pay a one of the things that I really pay a lot of attention to is Alzheimer's lot of attention to is Alzheimer's disease I was a big donor to Maria disease I was a big donor to Maria shriver's women's Alzheimer's movement shriver's women's Alzheimer's movement twice as many women as men get

24:00

twice as many women as men get Alzheimer's disease and the reason I Alzheimer's disease and the reason I care about it is I'm an anti-aging guy care about it is I'm an anti-aging guy and I don't want to create a world full and I don't want to create a world full of people who live to 130 140 150 and up of people who live to 130 140 150 and up who can't remember their own names who can't remember their own names because that's not okay and I want our because that's not okay and I want our elders who have developed wisdom to keep elders who have developed wisdom to keep giving me wisdom so I cultivate giving me wisdom so I cultivate friendships with people who are 20 and friendships with people who are 20 and 30 years older than I am because they 30 years older than I am because they save me huge amounts of time and save me huge amounts of time and generally I think the exchange is fair generally I think the exchange is fair because they apparently like company because they apparently like company from people who aren't exactly their age from people who aren't exactly their age so this is how it's supposed to work in so this is how it's supposed to work in society Alzheimer's stopped that and it society Alzheimer's stopped that and it breaks the passing of wisdom so I wrote breaks the passing of wisdom so I wrote a whole book on that that's my a whole book on that that's my headstrong book on Alzheimer's and headstrong book on Alzheimer's and cognitive function and hacking your cognitive function and hacking your brain so what do we know now how about brain so what do we know now how about infrared and Alzheimer's that we didn't infrared and Alzheimer's that we didn't know before help nah again can going back to that switch

25:00

nah again can going back to that switch like if there is a type of a switch in like if there is a type of a switch in your brain it helps the brain regulate your brain it helps the brain regulate um and change the neurons to um and change the neurons to improve the improve the um the the the function of the brain so um the the the function of the brain so what Dr Hamblin introduced us to many what Dr Hamblin introduced us to many many studies that have been done with many studies that have been done with infrared using like taking near infrared infrared using like taking near infrared LEDs and putting them like as helmets on LEDs and putting them like as helmets on the head and taking before and after the head and taking before and after pictures and then the Imaging of the pictures and then the Imaging of the brain before and after is it's you know brain before and after is it's you know it's really it's really um very impressive because it shows how um very impressive because it shows how before the the brain it's it's you can before the the brain it's it's you can you know see kind of the inflammation you know see kind of the inflammation and the the lack of function and the the lack of function um and then afterwards after using the um and then afterwards after using the near infrared near infrared LEDs on the the brain a completely

26:00

LEDs on the the brain a completely different healthy you know brain so it's different healthy you know brain so it's reducing the inflammation it's helping reducing the inflammation it's helping you know you a lot of times connect with you know you a lot of times connect with a pituitary gland there's lots of a pituitary gland there's lots of different theories we're learning more different theories we're learning more and more all the time about the and more all the time about the mechanism of action you know what we mechanism of action you know what we know now is there is a for sure a know now is there is a for sure a benefit there's also a benefit with benefit there's also a benefit with Parkinson's for the same and other types Parkinson's for the same and other types of brain brain disorders of brain brain disorders by now people who are listening have by now people who are listening have maybe heard me talk about my very first maybe heard me talk about my very first experience with infrared in the brain I experience with infrared in the brain I bought an 880 nanometer emitter that a bought an 880 nanometer emitter that a semi-crazy brain hacker put out in a semi-crazy brain hacker put out in a Yahoo group that he maybe sold 200 of Yahoo group that he maybe sold 200 of these before he disappeared them from these before he disappeared them from the market and this was a targeted tool the market and this was a targeted tool for shining infrared into your skull and for shining infrared into your skull and stimulating the brain and for a couple stimulating the brain and for a couple years even when I was first starting uh

27:00

years even when I was first starting uh bulletproof I was using this thing bulletproof I was using this thing really regularly because it gave me my really regularly because it gave me my brain back I had suffered from uh brain brain back I had suffered from uh brain damage from mold toxins I was recovering damage from mold toxins I was recovering from that and I had this whole host of from that and I had this whole host of things like fibromyalgia and I could things like fibromyalgia and I could shine this thing on my brain for one or shine this thing on my brain for one or two minutes and I'd get my brain back I two minutes and I'd get my brain back I I think there's great evidence for I think there's great evidence for infrared light on the head it's why any infrared light on the head it's why any LED infrared device that you have is LED infrared device that you have is beneficial but it doesn't come close to beneficial but it doesn't come close to the dose or the whole body things that the dose or the whole body things that you get from a sunlight and sauna if you get from a sunlight and sauna if you're sitting in a sunlight and you're you're sitting in a sunlight and you're getting the detox effects which you getting the detox effects which you don't get from LEDs at all you're don't get from LEDs at all you're getting the brain stimulating effects we getting the brain stimulating effects we just talked about and you're getting the just talked about and you're getting the energy effects so in terms of energy effects so in terms of of benefits per minute of benefits per minute I look at my sunlight in session as a

28:00

I look at my sunlight in session as a like I'm stacking many many different like I'm stacking many many different things just from sunlight including the things just from sunlight including the recipes and then I will listen to an recipes and then I will listen to an audiobook I've used my brain tap but I audiobook I've used my brain tap but I kind of sweat on it uh when I'm in there kind of sweat on it uh when I'm in there uh you can also I sat in my sunlighten uh you can also I sat in my sunlighten during the pandemic with my son and we during the pandemic with my son and we read the daily stoic and just had cool read the daily stoic and just had cool conversations so it's either social time conversations so it's either social time or it's biohacking time or it's or it's biohacking time or it's meditation time you can also do breath meditation time you can also do breath work when you're in it and so I just work when you're in it and so I just feel like it's the most effective use of feel like it's the most effective use of time to get all those benefits and if time to get all those benefits and if you don't really want to do you don't really want to do cardiovascular exercise cardiovascular exercise um well you can just sit in there and um well you can just sit in there and you get the cardiovascular stimulating you get the cardiovascular stimulating benefits seriously sit in your sauna benefits seriously sit in your sauna read something you love and then just go read something you love and then just go for a walk later that's kind of my for a walk later that's kind of my recipe for doing stuff like that right recipe for doing stuff like that right we know for sure speaking of we know for sure speaking of cardiovascular because that's when we cardiovascular because that's when we started the company all those years ago started the company all those years ago the only data that was out was you know the only data that was out was you know from Asia and it was all on the from Asia and it was all on the cardiovascular system with far infrared

29:00

cardiovascular system with far infrared specifically and showing the benefits of specifically and showing the benefits of far infrared on the heart and improving far infrared on the heart and improving the circulatory system as well as the circulatory system as well as increasing circulation and increasing circulation and um changing the changing the endothelial um changing the changing the endothelial lining so that blood you know had a lining so that blood you know had a greater flow in the body and and then we greater flow in the body and and then we did a study I don't think we talked did a study I don't think we talked about this before but a study in 2005 a about this before but a study in 2005 a clinical trial double-blind clinical trial double-blind placebo-controlled randomized studying placebo-controlled randomized studying at the University of Missouri Kansas at the University of Missouri Kansas City and showed City and showed um with the far infrared the solo domes um with the far infrared the solo domes that now you know are a great option for that now you know are a great option for you know potentially treating depression you know potentially treating depression showed a significant reduction in blood showed a significant reduction in blood pressure so that's another you know we pressure so that's another you know we talked about detox for for farmfra which talked about detox for for farmfra which is 100 you know really kind of the is 100 you know really kind of the leading one as well as the immunity but leading one as well as the immunity but the cardiovascular benefits of having a the cardiovascular benefits of having a healthy heart and lowering blood healthy heart and lowering blood pressure increase in circulation is also

30:00

pressure increase in circulation is also a great benefit of farm infrared as well a great benefit of farm infrared as well so now is the the solo model that you so now is the the solo model that you make does all of the different make does all of the different frequencies not just far right the solo frequencies not just far right the solo is really is really um just I mean it has a little bit of um just I mean it has a little bit of mid because it you know the ranges mid because it you know the ranges obviously they cross over obviously they cross over um but it does not it does not have near um but it does not it does not have near infrared it does have what it does have infrared it does have what it does have the that's different than all three the that's different than all three wavelengths that we talked about it does wavelengths that we talked about it does have your traditional light therapy as have your traditional light therapy as in colored lights not not lights as in in colored lights not not lights as in you know the near red red light spectrum you know the near red red light spectrum but colored light so we do have every but colored light so we do have every solo is equipped now with all of the solo is equipped now with all of the different colors of the rainbow so that different colors of the rainbow so that you can if you do you want to have like you can if you do you want to have like you said at the night at night if you you said at the night at night if you want to switch your lighting to Red you want to switch your lighting to Red you know or orange or you know have a little know or orange or you know have a little bit more subdued you can have that on bit more subdued you can have that on the solo that will be surround like as the solo that will be surround like as your head is lying out your head in the your head is lying out your head in the solo your head is out and the lights are

31:00

solo your head is out and the lights are surrounding the entry so you see them surrounding the entry so you see them you know they kind of go into your brain you know they kind of go into your brain like you know because you're getting like you know because you're getting some uh some traditional color therapy some uh some traditional color therapy out of it exactly that makes that makes out of it exactly that makes that makes sense so uh I I think I'm a fan of sense so uh I I think I'm a fan of having a full sunlight and uh when having a full sunlight and uh when possible but if you're getting just far possible but if you're getting just far infrared from the solo it's more infrared from the solo it's more affordable but you're not getting the affordable but you're not getting the mid-range stuff like the full mid-range stuff like the full programmability programmability um I haven't tried the solo um so I um I haven't tried the solo um so I didn't realize that it didn't have the didn't realize that it didn't have the mid in there but that makes that makes mid in there but that makes that makes sense I saw it at the conference but the sense I saw it at the conference but the solo is the one that that emulates solo is the one that that emulates what's being done in that study right what's being done in that study right now in California because the purpose of now in California because the purpose of this study is the increasing increasing this study is the increasing increasing the core temperature right so increasing the core temperature right so increasing the core temperature and doing it in an the core temperature and doing it in an accessible format that's something you accessible format that's something you could do at home so people what does it could do at home so people what does it cost cost the solo let it's under the solo let it's under um three thousand so if you get there's

32:00

um three thousand so if you get there's two elements there's the solo domes and two elements there's the solo domes and then there's also a heated then there's also a heated um sunlight and Pad that's underneath um sunlight and Pad that's underneath that you you don't have to purchase that that you you don't have to purchase that if you don't want to the original study if you don't want to the original study that was done was just done with the that was done was just done with the domes so you don't have to purchase it domes so you don't have to purchase it it just gives you that complete you know it just gives you that complete you know heat all the way around you and that the heat all the way around you and that the pad and does increase the cost so you pad and does increase the cost so you can probably get the solo you know can probably get the solo you know closer to you know 24 2500 closer to you know 24 2500 okay so it starts at 24 okay so it starts at 24 2500 and up if you want to add cool 2500 and up if you want to add cool stuff but they go to sunlighten.com Dave stuff but they go to sunlighten.com Dave and mention Dave and magically you can and mention Dave and magically you can save a bunch of money up to 600 save a bunch of money up to 600 depending on what they're getting so depending on what they're getting so that's the gift guys you know if someone that's the gift guys you know if someone comes on the show who has a product they comes on the show who has a product they make that's research based that works make that's research based that works for biohacking they have to share the for biohacking they have to share the love with you and so there you go love with you and so there you go there's your your discount sunlight.com there's your your discount sunlight.com Dave and you can save up to six hundred

33:00

Dave and you can save up to six hundred dollars I've been using sunlight for a dollars I've been using sunlight for a decade this is a very solid company with decade this is a very solid company with solid research as you can tell solid research as you can tell now now I'm very interested because when we I'm very interested because when we planned you know what science we're planned you know what science we're going to cover before the show you going to cover before the show you talked about chromophores tell me what talked about chromophores tell me what is a chromophore yes our team loves is a chromophore yes our team loves chromophores chromophores um because because so Dr Hamlin so um because because so Dr Hamlin so backing up so Dr Hamlin is connecting us backing up so Dr Hamlin is connecting us with all of the new research on light with all of the new research on light right and and all the benefits and so my right and and all the benefits and so my team talks in that language essentially team talks in that language essentially they're they're the cells that um they're they're the cells that um they're like okay here's here's going they're like okay here's here's going back to the quarterback right they are back to the quarterback right they are the receivers that are receiving the the receivers that are receiving the light light uh and then they decide you know if it's uh and then they decide you know if it's for example if you're going to do a for example if you're going to do a short pass that would be a that is as a short pass that would be a that is as a near-infrared pass right and then they near-infrared pass right and then they take that they store it they convert it

34:00

take that they store it they convert it into into um into energy or um and then that um into energy or um and then that transforms the body let me transforms the body let me zoom in on that because I think it's zoom in on that because I think it's important for biohacking not just for important for biohacking not just for infrared and for saunas infrared and for saunas if you look at if you look at the cells even bacteria other things the cells even bacteria other things like this they have specific frequency like this they have specific frequency range light receptors so they can only range light receptors so they can only see a certain kind of light so we have see a certain kind of light so we have chromophores that can see red and ones I chromophores that can see red and ones I can see green and blue and some of those can see green and blue and some of those are tied to circadian timing and things are tied to circadian timing and things like that but we also have them for like that but we also have them for infrared even though our eyes don't see infrared even though our eyes don't see it because our brain's like ah you don't it because our brain's like ah you don't need to worry about that you'll just need to worry about that you'll just feel the warmth on your skin because feel the warmth on your skin because seeing infrared for our species doesn't seeing infrared for our species doesn't work your chromophores are very work your chromophores are very important and the fact that we have them important and the fact that we have them for different frequencies of infrared for different frequencies of infrared that's why you can run a sunlight and that's why you can run a sunlight and program that changes infrared even program that changes infrared even though you don't see it we know from a though you don't see it we know from a cell biology perspective that something

35:00

cell biology perspective that something important is happening there and what Dr important is happening there and what Dr Hamblin study that you're just Hamblin study that you're just referencing was he was saying well okay referencing was he was saying well okay what does infrared do to these different what does infrared do to these different chromophores and can you summarize what chromophores and can you summarize what he found he found yes so he's finding that you're there yes so he's finding that you're there like you said you know all of the all of like you said you know all of the all of the Como fours respond differently and the Como fours respond differently and that what's really important is that that what's really important is that near infrared specifically is going to near infrared specifically is going to be absorbed by the mitochondria be absorbed by the mitochondria and so the mitochondria and then the and so the mitochondria and then the foreign sorry the farm for red is going foreign sorry the farm for red is going to be absorbed by water and what's to be absorbed by water and what's really important about this this like really important about this this like people are listening to Collective it people are listening to Collective it may not resonate as it does with people may not resonate as it does with people who have studied infrared for a long who have studied infrared for a long time but for years people used to think time but for years people used to think that that far infrared because of the fact that it far infrared because of the fact that it increases your core temperature and it's increases your core temperature and it's great for detox people used to think great for detox people used to think that far infrared was the one that was

36:00

that far infrared was the one that was really absorbed deeply the reality is is really absorbed deeply the reality is is that the water is the receiver in your that the water is the receiver in your body for farm for it which is really body for farm for it which is really important to understanding the mechanism important to understanding the mechanism of action and how the body responds and of action and how the body responds and then for then for near-infrared it's the mitochondria near-infrared it's the mitochondria um and then that it converts into energy um and then that it converts into energy which we've already kind of talked about which we've already kind of talked about and that you know is stored and then it and that you know is stored and then it helps to provide really more helps to provide really more like a bike batteries inside your cells like a bike batteries inside your cells you know so that you get you have energy you know so that you get you have energy there when you need it or if you get there when you need it or if you get sick you can you know you can pull from sick you can you know you can pull from that so that's why it's it's so that so that's why it's it's so important to understand important to understand um Dr Hamlin's research and studies and um Dr Hamlin's research and studies and when how chromophores respond and which when how chromophores respond and which wavelength is the right one because wavelength is the right one because otherwise again you're just thinking a otherwise again you're just thinking a light bulb is a light bulb as a light light bulb is a light bulb as a light bulb or infrared is infrared and it's

37:00

bulb or infrared is infrared and it's it's not at all the case it's really it's not at all the case it's really interesting that near and mid is interesting that near and mid is mitochondrial stimulating because if you mitochondrial stimulating because if you think about it your neurons have about think about it your neurons have about 15 000 mitochondria in them and your 15 000 mitochondria in them and your normal cells have a few hundred normal cells have a few hundred mitochondria so if you can improve mitochondria so if you can improve mitochondrial function your neurons by mitochondrial function your neurons by definition are ready to have a party definition are ready to have a party this new research that you're this new research that you're referencing here says okay if you can do referencing here says okay if you can do far infrared you get that effect but you far infrared you get that effect but you get the mitochond 100 and the healing get the mitochond 100 and the healing especially the neurological healing especially the neurological healing effect from a different Spectrum in it effect from a different Spectrum in it yeah Dr Hamblin recommends he's really yeah Dr Hamblin recommends he's really passionate about passionate about the lower temperatures be because your the lower temperatures be because your body your water molecules are tuned in body your water molecules are tuned in to be around you know nine to the to be around you know nine to the frequency to receive the infrared around frequency to receive the infrared around nine microns in order to for your body nine microns in order to for your body to receive the wavelength around that to receive the wavelength around that the surface temperature of the heater

38:00

the surface temperature of the heater has to be has to be essentially as cool as possible so his essentially as cool as possible so his perfect scenario would be get inside of perfect scenario would be get inside of sunlight and sauna turn it on sunlight and sauna turn it on and have the near infrared on have the and have the near infrared on have the farm thread on and get in right away a farm thread on and get in right away a lot of people get stuck at oh I want to lot of people get stuck at oh I want to preheat it and I want it to heat up and preheat it and I want it to heat up and I don't want to get in until it's hot I don't want to get in until it's hot and they get really you know like really and they get really you know like really stuck on the sweating aspect but and stuck on the sweating aspect but and sweating is great and we could talk sweating is great and we could talk about the bus study I mean there's lots about the bus study I mean there's lots of great science on study on sweating of great science on study on sweating but reality is you want that that but reality is you want that that wavelength to be absorbed right you want wavelength to be absorbed right you want that to get into your body you don't that to get into your body you don't want it to be in the air and it gets want it to be in the air and it gets absorbed into the body the best absorbed into the body the best resonance is the coolest resonance is the coolest temperatures and from the heater and temperatures and from the heater and then it starts to heat up and then the then it starts to heat up and then the body starts to change and you start to body starts to change and you start to sweat and you start you know then you sweat and you start you know then you get other benefits so it kind of evolves

39:00

get other benefits so it kind of evolves you know as you sweat now you're you know as you sweat now you're starting to detox which is a different starting to detox which is a different benefit than inflammation it's just it's benefit than inflammation it's just it's fascinating this whole biochemical fascinating this whole biochemical reaction from the different wavelengths reaction from the different wavelengths it's it's really incredible when you think about really incredible when you think about where we're going to go with infrared where we're going to go with infrared Technologies tell me what's coming next Technologies tell me what's coming next for sunlight and if whatever you can for sunlight and if whatever you can talk about because talk about because it seems like we've already figured out it seems like we've already figured out these three wavelengths but there's got these three wavelengths but there's got to be some other stuff that you think to be some other stuff that you think we're going to figure out where do you we're going to figure out where do you think we're gonna go yeah so we're think we're gonna go yeah so we're looking into sleep you know into more looking into sleep you know into more and more science and sleep we're looking and more science and sleep we're looking into other neurological brain into other neurological brain um you know research and brain science um you know research and brain science um we're expanding on the um we're expanding on the um near infrared as well as you know red um near infrared as well as you know red light and really understanding light and really understanding um you know the crossover there

um you know the crossover there and and um and we have some other things that I um and we have some other things that I can't share yet because can't share yet because um you know I um but we're I mean Dave um you know I um but we're I mean Dave this is It's amazing because I'm still this is It's amazing because I'm still having fun you know we've been doing having fun you know we've been doing this you know for a long time but as this you know for a long time but as science is evolving as we're learning science is evolving as we're learning why the wavelengths work the what the why the wavelengths work the what the body the way it does now it's making all body the way it does now it's making all the intuition and my experiences and the the intuition and my experiences and the letters and the stories that I received letters and the stories that I received for all these years of people saying oh for all these years of people saying oh my God this changed my life and it did my God this changed my life and it did this and I had Mercury toxicity this and I had Mercury toxicity um you know I had whatever different um you know I had whatever different types of conditions now I types of conditions now I scientifically understanding okay so scientifically understanding okay so this is which wavelength this is how it this is which wavelength this is how it did it this is why it did it and now we did it this is why it did it and now we just continue to you know um hone in on just continue to you know um hone in on on different types of of on different types of of um parts of the body and just understand um parts of the body and just understand as much as we can so we're we're as much as we can so we're we're committed to the science and it's it's

41:00

committed to the science and it's it's it's been very rewarding speaking of it's been very rewarding speaking of science something that I appreciated on science something that I appreciated on our last episode we talked about some our last episode we talked about some evidence for finding a lot more toxins evidence for finding a lot more toxins in sweat from infrared but it turns out in sweat from infrared but it turns out that wasn't a study which is what we had that wasn't a study which is what we had talked about and you let me know that talked about and you let me know that was based on observations in a doctor's was based on observations in a doctor's office but that it wasn't formally office but that it wasn't formally studied so I wanted to to call that out studied so I wanted to to call that out which is cool but you also brought to my which is cool but you also brought to my attention the blood urine sweat study attention the blood urine sweat study and talk to me about that yeah this is a and talk to me about that yeah this is a fascinating study that was done from Dr fascinating study that was done from Dr genuis in Canada who wanted to genuis in Canada who wanted to essentially use an OB gynawanda essentially use an OB gynawanda understand women's response to understand women's response to environmental toxins which is kind of environmental toxins which is kind of the reason why he committed to doing the reason why he committed to doing study the findings were that study the findings were that more toxins were removed with sweat than

42:00

more toxins were removed with sweat than with blood and urine in fact with blood and urine in fact Mercury specifically Mercury specifically they're what they measured the they're what they measured the participants blood and found no evidence participants blood and found no evidence of mercury however of mercury however 15 of those peop of those individuals 15 of those peop of those individuals that had zero had a hundred like all of that had zero had a hundred like all of them had mercury in their sweat them had mercury in their sweat so if you were just measuring blood if so if you were just measuring blood if you're just measuring you know the you're just measuring you know the toxins in blood you potentially could be toxins in blood you potentially could be missing missing toxins that are stored in your body and toxins that are stored in your body and and then take it one more step and then take it one more step they found that in an infrared sauna he they found that in an infrared sauna he released more toxins than traditional released more toxins than traditional saunas and exercise and specifically saunas and exercise and specifically they measured I mean there's a lot of

43:00

they measured I mean there's a lot of them but them but um the ones that come to my Mercury um the ones that come to my Mercury because that's a that's obviously you because that's a that's obviously you know a really difficult one to remove know a really difficult one to remove from the body cadmium from the body cadmium nicotine uh arsenic aluminum lead nicotine uh arsenic aluminum lead were some of the ones that were were were some of the ones that were were more effective using an infrasana via more effective using an infrasana via sweat than other other ways such as sweat than other other ways such as exercise and traditional saunas so that exercise and traditional saunas so that was the big the big findings is is was the big the big findings is is there's ways to remove toxins through there's ways to remove toxins through other ways but sweat is a really other ways but sweat is a really powerful it's not just a lot of people powerful it's not just a lot of people say oh sweat is just great for say oh sweat is just great for thermoregulation and but it's actually a thermoregulation and but it's actually a great way to remove toxic elements and great way to remove toxic elements and and we know for sure in infrared sauna and we know for sure in infrared sauna it can be more effective I'm not a huge it can be more effective I'm not a huge fan of exercise huge and I always say fan of exercise huge and I always say you know it's great you sweat and all you know it's great you sweat and all sweat is good but if you can if you can sweat is good but if you can if you can change your body so that you're removing change your body so that you're removing heavier toxins and toxins that can't be

44:00

heavier toxins and toxins that can't be removed other ways through nymphades on removed other ways through nymphades on a you know may be a good resource for a you know may be a good resource for you you so it's important that you get into your so it's important that you get into your sauna when you turn it on because you're sauna when you turn it on because you're going to be absorbing the types of going to be absorbing the types of infrared that don't heat you up very infrared that don't heat you up very much and they have direct biological much and they have direct biological effects on Cell healing and on energy effects on Cell healing and on energy production in cells and as it gets production in cells and as it gets hotter and as you start sweating it the hotter and as you start sweating it the benefits continue for the first types of benefits continue for the first types of infrared but then you get more of the infrared but then you get more of the detox benefits and these are things that detox benefits and these are things that simply don't get released in urine but simply don't get released in urine but they do get released in sweat and that's they do get released in sweat and that's a another question for you though uh a another question for you though uh should you shower right after you get should you shower right after you get out are you likely to reabsorb those out are you likely to reabsorb those toxins do you think about that much toxins do you think about that much you know we get asked you know we get asked a lot and a lot and there's different schools of of thought there's different schools of of thought to that some people you know say it that to that some people you know say it that that they are not going to be reabsorbed that they are not going to be reabsorbed some people say that you should shower

45:00

some people say that you should shower right away right away um so most um so most people do rinse you know you'll sauna people do rinse you know you'll sauna and then shower and you can go straight and then shower and you can go straight to sleep to sleep um so most people do um so most people do um you know I mean I typically my new um you know I mean I typically my new thing is to sweat stack and keep my keep thing is to sweat stack and keep my keep my core temperature up as much as my core temperature up as much as possible as long as possible if I can do possible as long as possible if I can do soda at the end of this one stacking soda at the end of this one stacking great but sometimes sometimes it doesn't great but sometimes sometimes it doesn't work out that way so I'll go from sauna work out that way so I'll go from sauna to something else and to something else and um I I have been you know I have been um I I have been you know I have been fine so do you have a personal fine so do you have a personal recommendation on that I'd love to hear recommendation on that I'd love to hear your thoughts uh I I believe mostly the your thoughts uh I I believe mostly the the old Queen of England the old Queen of England um from back in the day I I take a um from back in the day I I take a shower once a month whether I need it or shower once a month whether I need it or not that's something like the 1700s no I not that's something like the 1700s no I I as soon as I get out I'll rinse off I as soon as I get out I'll rinse off but I don't take a cold shower I take a but I don't take a cold shower I take a hot shower unless I'm doing contrast hot shower unless I'm doing contrast therapy and if I was doing that then I

46:00

therapy and if I was doing that then I would do hot cold hot cold hot cold and would do hot cold hot cold hot cold and I would end on cold but otherwise I I would end on cold but otherwise I think getting in the sauna and then think getting in the sauna and then taking a cool shower to cool down taking a cool shower to cool down defeats the purpose but getting in my defeats the purpose but getting in my sunlight and then staying sweaty after I sunlight and then staying sweaty after I just dumped a bunch of toxins I hate to just dumped a bunch of toxins I hate to say it but half the supplements that we say it but half the supplements that we swallow would work better if we just swallow would work better if we just smeared them on our skin your skin is an smeared them on our skin your skin is an absorption organ so I don't think it absorption organ so I don't think it makes sense to have mercury and other makes sense to have mercury and other stuff covering my skin if I'm detoxing stuff covering my skin if I'm detoxing so I will just super hot shower rinse it so I will just super hot shower rinse it off dry off quickly go about my day and off dry off quickly go about my day and still stay hot still stay hot perfect perfect now something else I wanted to ask you now something else I wanted to ask you about about I have noticed a very big change in my I have noticed a very big change in my cognitive function the next day after cognitive function the next day after usually a longer sunlight in session if usually a longer sunlight in session if I take activated charcoal during the I take activated charcoal during the sauna and glutathione afterwards what's sauna and glutathione afterwards what's your take on that your take on that heard the same thing from many other heard the same thing from many other people so I've heard there's

47:00

people so I've heard there's um I mean I've Heard lots of different um I mean I've Heard lots of different types of supplements to help do it with types of supplements to help do it with infrared and so I think if that works infrared and so I think if that works you know for for you I think that's I you know for for you I think that's I think that's great I mean we know it's think that's great I mean we know it's helping The Infrareds helping with your helping The Infrareds helping with your receptors and I'm sure that that you receptors and I'm sure that that you know the charcoal and everything else is know the charcoal and everything else is is as well so it makes sense is as well so it makes sense I I think the sauna is going to I I think the sauna is going to challenge your detox systems I'm sure challenge your detox systems I'm sure your kidneys and liver appreciate that your kidneys and liver appreciate that you bound some extra toxins during it you bound some extra toxins during it and that you helped with toxin detoxing and that you helped with toxin detoxing and transformation with glutathione so I and transformation with glutathione so I think it's a good practice charcoal think it's a good practice charcoal before glutathione afterwards and you'll before glutathione afterwards and you'll probably get more results but I haven't probably get more results but I haven't seen a study that's just how those work seen a study that's just how those work so that has to be how it works so that has to be how it works and guys one more time I want to share and guys one more time I want to share sunlighten.com Dave you can save up to sunlighten.com Dave you can save up to 600 bucks if you want to add this to 600 bucks if you want to add this to your biohacking stack your biohacking stack I really like having Asana because it

Thermoregulation as a Path Back to Equilibrium

Temperature is one of the body's quiet forms of intelligence. It rises, falls, and adjusts throughout the day, helping coordinate energy, sleep, and repair. When that rhythm becomes disrupted, the body can feel less settled. The episode presents depression through this lens, not only as an emotional state, but as a condition that can involve altered body-temperature regulation.

The practical insight is simple: a controlled rise in core temperature can be followed by a better cooling response. Connie describes the body as relearning the ability to move up and down rather than staying locked in one state. That rhythm is central to rest. When the body can cool at night, sleep becomes more accessible, and the mind has a clearer path toward stillness.

self-regulation works better

This explains why sauna before bed can feel restorative for some people even though heat itself is stimulating. The session warms the body first, then the period afterward allows temperature to come back down. That cooling phase is not an afterthought. It is part of the protocol, and it may be one reason a warm evening sauna can support deeper sleep instead of disturbing it.

A head-out infrared chamber changes the experience of heat. With the head outside the chamber, the session can feel more tolerable, and the body can warm over a longer span without the same sense of being enclosed by heat. This supports the goal described in the episode: raise core temperature gradually enough for the body to respond. Comfort becomes a tool for consistency.

The comparison to exercise is useful when kept precise. Exercise asks the body to regulate temperature, circulation, and recovery through effort. Passive heating asks for regulation through exposure. Both can create a rise-and-cool pattern, but sauna does it in stillness. For a recovery ritual, that distinction has power.

We view this as a practice of deliberate contrast within the body itself. You enter warmth, remain present, and give the system time to respond. Then you rinse, cool, hydrate, and let the body settle. The protocol is not defined by how much heat you can tolerate. It is defined by whether you leave with more balance than you brought in.

Sweat, Sleep, and Cellular Recovery

Sweat gives the body a visible language for release. In the episode, sweating is connected with reducing toxic load through the skin, especially when infrared heat helps the body produce a sustained sweat. The claim is framed practically: when the body sweats, it can help move certain burdens out. The feeling afterward is often one of lightness, not depletion.

That distinction matters because recovery should not leave you emptied. Connie notes that many people associate traditional high-heat sauna with feeling drained, while infrared can feel more restorative when the protocol fits the person. The right session supports the body without turning heat into strain. You finish clear, rinsed, and ready for rest.

Dave connects infrared exposure with the water inside cells and with mitochondrial function. In plain terms, he frames this as support for the body's ability to make usable energy, which can influence how restored and mentally clear you feel. He also links mitochondrial function with sleep quality because he describes mitochondria as powering the system that helps wash waste from the brain during sleep. The mechanism is complex; the felt outcome is simple, better recovery and cleaner rest.

The timing of a sauna session shapes the result. Some people can rinse after an evening sauna and go directly to sleep, while others need a longer pause to cool down. The episode makes room for that individuality. Your protocol should respect your response, because recovery improves when the body feels guided rather than rushed.

A thoughtful evening sequence is restrained. Heat the body, sweat, rinse with water that is not excessively hot, rehydrate, and allow temperature to normalize before bed. This sequence supports the cooling phase that makes sleep feel easier. The ritual ends not when the heater turns off, but when the body returns to calm.

Hydration and rinse habits also belong inside the protocol. Sweat changes fluid balance, and the skin carries what the session helped release. A rinse marks a clear transition from heat to rest. It turns the practice from a loose habit into an intentional recovery rhythm.

Infrared sauna works best when you listen closely. Session length, evening timing, cooling time, and intensity all influence whether the experience feels energizing or sleep-promoting. The goal is not to copy someone else's tolerance. The goal is to build a precise ritual that restores your own equilibrium.

Why the Infrared Spectrum Matters

Infrared is not one thing. The episode separates the spectrum into near, mid, and far infrared, each described as having a different role in the body. This is the difference between a vague wellness claim and a more intentional protocol. The wavelength mix shapes the experience.

Near infrared is connected in the conversation with cellular energy, skin response, and mitochondrial activity. Because mitochondria are described as part of how the body makes energy, this wavelength is associated with feeling more awake, restored, and clear after a session. The source emphasizes that near infrared is best delivered through LEDs rather than heat alone, because using heat to deliver it at meaningful levels would become excessively hot.

Mid infrared is described as a different tool, associated with pain and deeper comfort. That does not make it better or worse than the other ranges. It gives it a distinct role. For someone using sauna as part of recovery, the middle range can belong to the experience of ease, relief, and settling into the body.

you don't feel exhausted you don't feel drained you actually feel more energetic

Far infrared is linked with sweat, water molecules, and detoxification. Connie explains that far infrared is absorbed in relation to water molecules, creating movement that supports sweating and the release of toxic burden through the skin. The outcome people notice is not abstract. They feel cleaner, lighter, and more ready to recover.

Dose still governs the result. Distance from emitters, wavelength mix, surface temperature of the heaters, and session length all shape how the body receives infrared. The episode notes that many generic infrared saunas may offer only one wavelength range, often in the far-to-mid category. A more precise system allows the session to be shaped around the desired outcome.

This is why language matters. Saying infrared is beneficial is less useful than asking which wavelengths are present, how they are delivered, and what the session is designed to support. A detox-focused protocol, a pain-focused protocol, and an energy-focused protocol should not feel identical. They ask different things of the body.

A refined sauna practice is therefore less about maximum heat and more about intelligent exposure. You choose the wavelength mix, respect your distance from the source, stay long enough for the body to respond, and end with cooling and hydration. Precision creates harmony. The best protocol leaves you restored, not conquered.

otherwise again you're just thinking a light bulb is a light bulb or infrared is infrared
