The Science of How to Optimize Testosterone & Estrogen | Huberman Lab Podcast #15

This episode I discuss the hormones testosterone and estrogen and how they impact the brain, body, and behavior at ages after puberty. I also discuss how various behaviors such as exercise (resistance and endurance training) and sex, or observing sex impact these hormones and their levels. I ask: “what specifically is it about such activities that impact testosterone and estrogen?“; the resounding theme is that when our nervous system is activated in particular ways it drives our endocrine system and vascular system to activate or repress certain hormone networks in predictable ways. I also discuss peer-reviewed studies and protocols addressing (at a mechanistic level) how light, cold and heat, and respiration (breathing) can positively or negatively impact testosterone and estrogen. And we discuss specific supplements and compounds that peer-reviewed studies illustrate can adjust testosterone and estrogen levels: by changing their binding to other proteins, by raising them directly, or by changing
