Hormonal Health
Everything in the library on Hormonal Health — the protocols, the science, and what it feels like in practice.
Understanding the Impact of Cold Water Immersion on Testosterone Levels
The evidence on cold plunges and testosterone is sparse, the studies small, and the effect short-lived. What the data actually shows — and what it doesn't — is worth understanding before you build your recovery protocol around it.
Understanding Hormone Replacement and Ozone Therapy: A Path to Enhanced Wellbeing
Standard blood panels mark you as fine while you feel anything but. This is the case for hormone optimization — and how ozone therapy fits the same logic.
Insulin, Brown Fat & Ketones: The Science of Your Metabolic Engine
Insulin governs whether your body stores fat, silences brown fat, or burns it as heat. Dr. Benjamin Bikman explains the hormonal logic — and why ketones are the signal that shifts everything.
Understanding Kratom: Effects, Risks, and Individual Responses
Kratom binds the same receptor as morphine. Andrew Huberman walks through the science of why its addiction potential is real — and who is most at risk.
Mastering the Cold Plunge: Day Three of the Ultimate Human Challenge
Dr. Gabrielle Lyon answers the questions women have been asking — menstrual cycles, pregnancy, hot flashes — while Gary Brecka unpacks the circulatory science that makes cold immersion a precise longevity protocol.
Unlocking the Power of Cold Exposure: A Path to Enhanced Sexual Health
Cold exposure causes shrinkage in the moment — the adaptation that follows is what builds the vascular, neurochemical, and hormonal foundation for stronger sexual performance.
Unlocking the Benefits of Cold Exposure Therapy for Optimal Health
An engineering PhD built the world's first self-freezing ice bath to reclaim what modern comfort quietly erased — and the metabolic case for why deliberate cold may be the most efficient protocol available.
Understanding Male Sexual Health: Insights on Fertility and Testosterone
Male fertility is a shared responsibility — and sperm quality, testosterone, and erectile function are more connected to daily habits than most men realise. Dr. Michael Eisenberg clarifies what's actually declining, and why.
The Science of Temperature: Understanding Cold and Heat Exposure for Women
Cold exposure advice was built on male physiology. Dr. Stacy Sims defines the temperature thresholds — and the preference for heat — that produce genuine adaptation in women.
Period and Cold Exposure: Women's Considerations
Your menstrual cycle shapes cold tolerance — and cold exposure can ease the very symptoms that make the practice feel hardest. Two Wim Hof instructors on adapting your protocol, not abandoning it.
The Cold Truth: How Deliberate Cold Exposure Can Enhance Fertility and Hormonal Health
Cold exposure doesn't stimulate fertility directly — it removes the heat that quietly degrades it. Understanding that distinction clarifies exactly what a daily cold protocol can and cannot do for hormonal health.
The Optimal Recovery Protocol: Sauna vs. Cold Exposure for Women
Heat and cold are not interchangeable for women. Dr. Stacy Sims maps the temperatures, timing, and protocols that turn recovery into a hormonal and metabolic edge.
What Cold Exposure Does to Hormones, Stress, and Fertility | Dr. Tom Seager
Sarah Kleiner's cycle-timed cold protocol — pausing at ovulation, restoring leptin sensitivity, rebuilding mitochondrial function — produced the pregnancy two rounds of IVF could not.
This Sauna Protocol Annihilates Toxins - Bryan Johnson
Bryan Johnson measured toxins, microplastics, vascular growth, and fertility markers under one controlled variable: twenty minutes of dry sauna, every day. The data moved in ways the literature hadn't established.
Harnessing the Power of Infrared Sauna Therapy for Hormonal Balance and Longevity
Cortisol — not testosterone or estrogen — is the upstream gatekeeper of hormonal balance. Dr. Taz Bhatia explains the cascade, and the protocol that restores equilibrium from the root.
Unlocking the Power of Cold Exposure: A Natural Approach to Enhancing Erectile Function
Cold immersion isn't damaging your sexual health — it's training the mitochondrial and vascular machinery that performance depends on. An engineering professor explains the mechanism most men have never heard.
