In this episode, I discuss testosterone and estrogen hormones and how they impact the brain, body, and behavior 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. We discuss specific supplements and compounds that peer-reviewed studies illustrate can adjust testosterone and estrogen levels by changing their binding to other proteins, raising them directly, or changing other hormones released from the brain and pituitary. I discuss optimization in the normal reference ranges for these hormones, and I discuss pheromones, apnea, menstrual cycles, menopause and andropause.

In this episode, I discuss how hormones such as testosterone and estrogen and their derivatives impact the early development of the brain and body and their maturation. I review published data on environmental factors shown to powerfully alter hormone pathways in animals and humans and the effects of cannabis, alcohol and cell phones on testes, sperm, ovaries and hormones. I describe the predictable relationship between genes, beard growth and balding patterns, and the importance of estrogen for brain development in people of all chromosomal sexes. Finally, I discuss how the hormones we are exposed to in the womb shape the relative length of our finger digits, the sounds our ears make (yes you read that correctly), and how those correlate with people's self-reports of their sexual preferences. As always, basic information and tools are discussed. Read the full show notes for this episode at hubermanlab.com.

In this episode, I discuss the biology of emotions and moods in the context of relationships. I focus on the science of how early infant-caregiver attachment, combined with adolescence and puberty shape our adult patterns of attachment. I explain the three universal aspects of emotions, the reality of right-brain versus left-brain personalities, and how the roots of adult attachment are also grounded in specific aspects of puberty. I review what factors determine when puberty starts and ends, and the role of oxytocin and other chemicals in controlling how we perceive and remember others. As always, I refer to various practical tools including new tools for understanding and predicting our emotions before they occur, and neurochemicals that shape human connection.
