Infrared at the Cellular Level

Infrared operates differently than heat alone — altering cellular water, charging mitochondria, and building a physiological baseline that compounds with each session.

The Science of Sauna: Beyond the Heat

Heat therapy has been practiced for thousands of years, yet most people approach the sauna as a luxury rather than a deliberate recovery practice. Connie Zack spent years immersed in the science of infrared sauna technology, and her perspective reframes heat exposure not as passive relaxation but as cellular activation. What happens when you sit in heat is far more precise than most realize.

This conversation covers the difference between traditional and infrared sauna (discussed further here), the mechanisms of cellular detoxification, and the protocols that transform heat into a tool for resilience. Not all heat is created equal, and understanding the distinction matters.

is sauna all that people say it is or is it a bunch of hype let's talk about it today on this [Music] episode welcome back to the Sarah claner Wellness YouTube channel today I am talking with Connie from sunlighten she has quite an amazing story of how she actually got into sauna in the first place and I really wanted to bring her here just to ask her all the questions that I typically get about sauna and how it is beneficial for our body the difference between a regular sauna an infrared sauna and even a steam sauna these are questions I get quite often and red light therapy versus ass sauna and what are the actual benefits on the

2:00

balance within your body so make sure you check out all of those links I mentioned down in the show notes and let's jump into today's episode hello everyone welcome back to the show very excited to have Connie here today from sunlighten we're gon to talk all things SAA which is a a question that my community asked me about quite a bit so Connie is an absolute expert on this topic and thank you for being here Connie of course thanks for having me yeah I would love um if you want to give a little bit of background what got you personally so interested I think we always have a kind of a personal story that brings us into

4:00

saw this transformation I helped him get the business off the ground a couple years later um ended up joining forces so and I always wanted to make a difference at PNG I was really involved in a lot of nonprofit boards for the crony Colitis Foundation and for different types of heart disease states to help people um beyond the medical aspect beyond the medicine um because I just really believed in trying to figure out the Cure and when I saw my brother essentially you know cure himself with a natur Natural Therapy you know without any side effects just sitting in the comfort of his own home I was like oh my gosh um became really interested and

6:00

this was a way a natural way infrared you know we can talk about where it comes from the sun it's a natural line of energy um and healed him and so changed his life and you know ultimately I said I'm gonna jump out of a plane without a parachute and quit my great job and um joined forces with at that time um was my you know Beyonce and now is my husband and business partner and we dedicated the rest of our life to Bringing light hope and happiness to people everywhere wow it's amazing and you know my audience will definitely love the story because a lot of them come from a allopathic medical model and

8:00

being absorbed and penetrated into their body so you know we now have other ways you know other Solutions you know such as sunlight and saas so yeah I mean the sun in the middle of the day I was talking about this last night on my stories is you know like 402 around there percent infrared so if you're sunbathing in the middle of the day you're getting a really great you know punch pack of that infrared but how many people are actually like you said doing that most people in the middle of the day are working they're indoors they're they have jobs and if they don't they're not necessarily laying out in the sun because we've been

10:00

find um red light combined with invisible near infrared combined with mid infrared combined with far so you get the three parts of the healing spectrum of infrared plus you get the visible part of the near infrared Spectrum which is you know red light and there's some significant benefits and there's a synergistic effect between when you combine red and near you get a much um higher Effectiveness rate especially with skin and boosting the immunes cells and brain health I mean there's just so many benefits awesome yeah so it's kind of like a red light therapy panel essentially because those are ones

12:00

it's a affordable it's accessible it's easy to use you just plug it right in so super super easy solution I want to make sure I mentioned that because we are all about it sunlight and Sarah like access and you know we want to meet people where they are and not everybody needs to have four wavelengths it's you know that's um so solo is perfect we have a SAA it's called a signature which has Farm frad as well but it's in a wooden cabin it's not portable but some people want you know to sit in inside a wooden cabin with significant other or by themselves they want to have music playing you know and then we have amplify which is a um blend of all three

14:00

in um research on cortisol on you know helping to regulate the thyroid I mean there's it's mindblowing all the different you know ways that the mechanism of action the way infrared can heal your body um but really if you you know like sometimes I get so overwhelmed thinking my gosh it sounds like it's too good to be true you know and I don't like that feeling but but when I take a step back and I think our body are really designed to heal themselves if we treat them you know with the natural tools that we have you know then we can equip ourselves I mean your story for example I read your story and the fact that you you know we able to you know

16:00

uh to talk about the exclusion Zone water and the water that surrounds our cells you know 99% of our our body is this water molecule and I I would love to talk a little bit about how sauna can impact um that cellular water in a positive way as well yeah well um I I've heard my birdie told me that you the expert so I'd love to hear your perspective you know but I mean you know um infrared light is is proven you know to alter the state of water in our bodies and when it it does that um then it activates you know it helps with the mitochondria and it helps support proteins um so it makes that stronger and you essentially it helps

18:00

benefits and it makes more sense now that I know this because when I was first starting 25 years ago there was not the connected dots right so I just knew I felt better I knew I had more energy I you know I knew that my brother detoxified I knew that it helped with paint like I knew but I know why yeah and so I'd love to hear from you on you know your interpretation yeah and I mean I think my audience is the same like they they love like okay there is a scientific reason behind this but I just want to feel better and that's it so tell me the science but cool I I just want to implement this but I know that

20:00

he's like a they went and got in the sauna and he all of a sudden had all this energy and he's like wait a second you know and so um that is that's essentially what I take from that research is that it just gives our cells more of an energy capacity and when we have that we can better manage our metabolism um everything to our mood to hormones everything just works more efficiently and so I think that's really the value of these wavelength of light um that we're missing we're not getting we're indoors um so yeah so that that's my interpretation yeah well I think that's one of the reasons you know people one

22:00

um infrared like a sunlight and sauna right after a run or a walk or yoga or any type of cardiovascular activity it's exponentially more effective I mean it just U because you're already in a different state and it just takes that you know that state and accelerates it you know even faster so the health benefits the results you're going to find um you're going to get there faster when you stack it yeah and that's a question I get quite a bit of like when should I do sauna and I had a um one of my community members she was really stressed out because she's like the only time I have for sauna is first thing in the morning and I know that's not like

24:00

oh my goodness I didn't realize how healthy I was compared to so many people that yeah that I was come in contact with and they would struggle sweating and they would struggle I they just struggled and um so they're in a completely different state so I would tell them okay start slow you know you don't want to just kind of Dive Right In for 40 minutes like I do that's not what's going to work so yeah I think it's it's really important um I'm glad you mentioned that it's really important that everybody tries whatever is best and for that person that says you know I just don't have time or I don't you know

26:00

you know it really helps with that and so um it's been the greatest gift is just just doing it and then you figure out once you start how long you could do it for but not doing it because you don't have 30 minutes or 40 minutes or whatever yeah my my um partner Carrie we have a podcast together called Quantum conversations she is a big fan of sometimes just going in the sauna and just turning it on and sitting in there while it's Heating up because she's tell you're getting all that infrared and it actually energizes your body because we work with quite a few women who want to get pregnant and you know and they're

28:00

it because it's the longest wavelength because the surface temperature is the coolest so if you just kind of picture this long smooth kind of an ocean you know like just but very smooth wave that's easier for the body to absorb it and to get into the water molecules and vibrate those water molecules and charge them you know and detoxify then once it because the longer it heats up up then the shorter the wavelength becomes the choppier choppier is that a word I think yeah is it it didn't sound right when I said it um the shoulder so it it becomes more difficult and challenging for the body to um absorb that and receive it in the way it's designed to do like when

30:00

different than the way that we do it now or just alone in our homes and so yeah I think it it helps to have these these things like sauna and I've got a cold plunge too that I have right next to the sauna and um those things have been really huge for me over the last year of just recovering um and all my you know circadian practices grounding all that stuff it's been like a different recovery from at the age of 44 than it was at age of 28 with my daughter it's been like night and day I mean I haven't dealt with the postpartum depression the weight just easily melted off I didn't have to like go kill myself in the gym it just kind of came off and I think

32:00

grew up with which is great yeah I agree 100% it's it's so important to teach these things um so I wanted to ask really quickly because I I actually just got this question um my friend Carrie and I we did a podcast about red light and sauna and somebody asked uh what's the difference between a steam sauna and infrared sauna my answer was the core temperature really is what you're getting from that steam sauna but the INF you're getting all these other benefits was I correct on that or I would love to hear your expert expert answer on that um so it's it's very it's a very different experience and it's very different

34:00

skin I mean the the skin when it is a is it will look different if you do steams all the time Steam for a little bit is good I nobody I mean I love like a good Steam on my face to every now and then yeah every now and then um but really your the really two best ways to treat your skin is purification from the inside out to have your skin glow because it's it's removing I mean we're you know we're exposed to what is it 700 thousand I think chemicals each day that are in our air and water and clothes and everything and so um you know that gets into our bodies and that affects how our skin looks so you have to purify this the skin and then the the near INF for

36:00

better and that feeling better inspires them to do it again and again um and so that's important because if you don't feel great and enjoy it then your chances of doing it again and again probably aren't as you know um probably not going to happen and then you if you don't do it then you're not going to get the results I hope you're enjoying today's episode here on the Sarah Kleiner Wellness YouTube channel just a quick little reminder that if you are enjoying this episode to please hit that like button and leave a comment and if you are interested in getting a sunlight and sauna you can save $ 600 by using the link in the show notes below

38:00

tips on that for people yeah I do um so I have two answers one is as far as figuring it out for yourself which is my favorite um because you know everybody is different um my analogy would be um hopefully we have some people listening that um like like either you know some type of outdoor exercise you know it doesn't have to be running but I always like I always use running because um there's always a moment when you run every single time where it's a struggle and then if you just keep pushing and pushing you kind of get into the zone you know um and then you feel like you can just let go forever and for everybody that's different and um it's

40:00

massage and other types of um of treatments but I stayed down there for a week and just talk to everybody about how they felt after you know using sunlight and sauna and um one of the consistent pieces of feedback is they noticed that go after some people was different but most of the people said I noticed that after 30 minutes I wanted I felt exponentially better from 30 to 40 and so um and again it's not true for everybody I don't want people to like hold me to you know to that because some people it's 20 to 30 but there is a point where all of a sudden you're just like oh my goodness I like I'm in love this is so awesome and so we

42:00

Cascade of benefits starts to happen and you don't want to leave then right like like you really want to stay you know and um shut everything down and enjoy you know the healing therapy and then you can stay in there you know you can stay in that longer um you know hydrate listen to your body um make sure you're you're supplementing your body with you know electrolytes and and you know I don't know do you have certain electrolytes that's something we always get asked do you like when you SAA do you have a certain um nutrition protocol or anything that you do I love the um Kon hypertonic minerals I use those a lot um and if I do sauna if I've done a

44:00

every day you know and I don't recommend somebody to run every day but can you yes you can you just you know you just have you have to find ways for your body to recover and give your body everything that you know it needs I you know two to three times a week is is awesome and if you can get into that you know habit of doing it you know the other thing I will mention one of my favorite benefits of when I in my sauna is I can do other things that benefit my body because I think we're just all so stressed trying to get to the next thing and there's very few Wellness opportunities where you can do something else while benefiting from the initial

46:00

so it's it's difficult for me to meditate I I start and then I like you know get out of that little Zone um but it's great to journal you know it's great to for intention um visualization goal setting I there's just so many things that you can do you know yoga you know um while you're doing it which is it's just a rare you start thinking about you know your life and you know it's not often that you can do two things at once that would benefit you um from a self-care standpoint yeah I just take the time to just relax sometimes I'll just kind of put my legs up the wall love that deep yeah do the deep

48:00

very expensive piece of equipment but essentially it's the same I mean the goal of that treatment was to increase the core temperature and what they're finding is that um people who are depressed have um are unable to Thermo regulate so they're kind of stuck in what I call like the switch where it's like the onoff button is not working and the infrared energy helps to unlock that um that switch that's stuck helps the body to heat up and then most importantly to cool down right because a lot of people who have issues their body isn't able to cool down and so that's why they have problems with sleep and that's you know I mean this is what uses

50:00

you know so there's both on on far infed and and near infrared as well as red light um benefits for the brain and depression so I think that's really promising you know I and people who are depressed are in a really you know dark dark place and hopefully we're bringing some light you know to their darkness and um and we could help them absolutely um so that's it's really important to me because I am just all about you know people living healthy happy lives and however that they can and so it it's painful to me to hear the just horrible statistics about depression and um yeah all those different stuff so there's a solution

52:00

scientifically and it sounds like you know that's not as important but I want people to know there is um I saw one of your values is you know transparency and um and that's really that's be true is one of sunlight and's values and we also have a science we want to make sure we you know back up anything that we say and so detoxification for a long time everybody knew that they were getting rid of toxins but they didn't really understand you know um and now there's you know additional science that backs up everything that we've claimed which essentially says that you know um more toxins are removed from sweat than you know that the more toxins were found in

54:00

immune system I think we briefly talked about that but I mean as we get into the winter and you know there viruses and colds I mean you know I mean we're the infrared is going to help stimulate white blood cells and heat shock proteins and fight you know fight the viruses um that are out there and so makes your body and it makes your mitochondria is stronger it makes your protein it just helps to not only obviously we talked about the energy level but it helps to get your body your cells stronger and um have them like you know I just kind of picture like I have these like little Warriors inside they like okay come on bring it on you know

56:00

those little armor jackets on your cells and make them stronger and make so that they can fight you know coals and they can fight it and that's how I always and I did this with my kids when they were you know younger I'm like we're gonna fight through this you know we can do this and um so I would definitely recommend sometimes when you're really really sick you know you just it doesn't you you have to that's one it's different for everybody sometimes it like I've done it all the different ways and sometimes it feels great and I'm like I'm so glad I did that oh my gosh amazing you know and sometimes you know then like I get more tired and um so it

58:00

and that can be a very he we we're afraid of fevers we don't want to take the Tylenol and all that stuff which is a whole other uh whole other podcast about why I don't recommend that but allowing your body to induce its own fever essentially that's how that's a healing response um for the body so yeah that's that's my thoughts yeah yeah I I completely agree I mean the fever is you you get your body in a regular state of increasing your core temperature you know even if it's only two to three days a week you will notice a big huge difference in the way you feel and and your body will be stronger and it will so that then you're you will be able to

60:00

time when you do and if you haven't any of our choices work the far infrared you know amplify or the smart Sonet so any of them will help with pain the smart Sonet is designed with the the four the three wavelengths plus red it is really specially engineered for decreasing inflammation at all different levels so if you you know if that's an area of your life where you are just you know like oh my gosh I'm in so so much pain and it's in my muscles it's in my feet it's in my you know um that's one time where I would say consider the the smart sauna because far infrared is going to go um G to heat up your core so

62:00

mean that gu I mean I'm so inspired by those people that can just do it over and over again that's just amazing yeah but I mean my my knees my foot you know every part of my body I remember that 20 mile run and I mean I came back and I could barely get down the stairs to get into my sauna and um I after a session I was like I just ran up the stairs I mean it's just amazing um so it's it's the benefit of all of the different wavelengths working together to decrease inflammation and to speed up Muscle Recovery um it's it's really very very therapeutic so that would just be the one thing if there's people who are listening who are um going through

64:00

get up to $ 600 off um which is you know again we're all about making a difference in this world and you can't do that unless you you know take some risks and offer things and and increase access as much as possible which is what we try to do at sunlight and so however we can help support you know the community to be a healthier place um is what makes us tick and fills our bucket so awesome happy to work with you is there a time limit on that or is that just something that you're willing to extend it's something that we're willing to extend there's no time limit on that yes wonderful yeah they just the the key factor in that is you okay well

66:00

Infrared vs. Traditional: The Mechanism Matters

Traditional saunas heat the air around you. You sweat because your environment is hot. Infrared saunas work differently—they emit wavelengths that penetrate tissue directly, raising your core temperature without requiring extreme ambient heat. The result is a deeper, more sustained physiological response at lower temperatures.

The distinction matters because the depth of tissue penetration determines what gets activated. Infrared wavelengths—particularly far-infrared—reach deeper into muscle and connective tissue, triggering heat shock protein production and mitochondrial adaptation. Your body responds as if it has been stressed, and that stress builds resilience.

"The benefit isn't just sweating—it's the cellular response to controlled thermal stress."

Detoxification Through Sweat: What the Research Shows

Sweating eliminates waste. The question is what kind of waste and how effectively. Research on infrared sauna use shows measurable excretion of heavy metals, BPA, and other lipophilic toxins through sweat—substances that traditional detoxification pathways (liver, kidneys) process more slowly.

This isn't about cleanses or magic cures. It's about providing an additional route for elimination. Infrared heat mobilizes stored toxins from adipose tissue, and sustained sweating moves them out. The protocol matters: consistency, duration, and post-session hydration all influence the outcome. You don't detox in one session. You build detoxification capacity over weeks and months.

Cardiovascular Adaptation: Training Without Movement

Heat exposure produces a cardiovascular load similar to moderate exercise. Your heart rate elevates, blood vessels dilate, and plasma volume increases. Over time, this adaptation improves endothelial function and cardiovascular efficiency.

Studies in Finland—where sauna use is deeply integrated into daily life—show strong correlations between frequent sauna sessions and reduced cardiovascular mortality. The mechanism runs through improved circulation, lower arterial stiffness, and enhanced autonomic balance. The sauna trains the cardiovascular system the way running trains the muscles.

Heat Shock Proteins: The Cellular Stress Response

When your body temperature rises, cells produce heat shock proteins—molecular chaperones that repair damaged proteins and protect against oxidative stress. This response is hormetic: a controlled stressor that makes cells more resilient.

Heat shock protein activation is one reason why regular sauna users report better recovery, reduced inflammation, and improved immune function. The body adapts to the challenge, and that adaptation carries over into other areas of life. The sauna becomes a training ground for cellular resilience.

Practical Takeaways

  1. Start with 20-30 minutes at moderate heat (120-140°F for infrared), 3-4 times per week. Build tolerance gradually.

  2. Hydrate before, during, and after. Heat stress depletes electrolytes—replenish with mineral-rich water or electrolyte solutions.

  3. Combine with cold exposure for contrast therapy—alternating heat and cold maximizes vascular training and recovery benefits.
