The Huberman Lab podcast is hosted by Andrew Huberman, Ph.D., a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioral sciences at Stanford School of Medicine. The podcast discusses neuroscience and science-based tools, including how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health, as well as existing and emerging tools for measuring and changing how our nervous system works. Huberman has made numerous significant contributions to the fields of brain development, brain function, and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills, and cognitive functioning. He is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award, given to the scientist making the most significant discoveries in the study of vision, in 2017. Work from the Huberman Laboratory at Stanford School of Medicine has been published in top journals, including Nature, Science, and Cell, and has been featured in TIME, BBC, Scientific American, Discover, and other top media outlets. In 2021, Dr. Huberman launched the Huberman Lab podcast. The podcast is frequently ranked in the top 10 of all podcasts globally and is often ranked #1 in the categories of Science, Education, and Health & Fitness.

Folge vom 03.05.2021Boost Your Energy & Immune System with Cortisol & AdrenalineThis episode I describe the biology of two essential hormones we all make: cortisol and adrenaline (also called epinephrine). Cortisol and adrenaline powerfully regulate our levels of energy, focus and immune system function. I describe various science-supported tools and practices to increase or decrease cortisol and/or adrenaline, depending on one's specific needs and goals. I also describe the biology of nootropics, and how cortisol and adrenaline can improve or degrade learning. Finally, I review the scientific data and tools for timing the release of these hormones to improve memory, energy and immune system function.

Folge vom 26.04.2021How to Control Your Metabolism by Thyroid & Growth HormoneThis episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.

Folge vom 19.04.2021How Hormones Control Hunger, Eating & SatietyThis episode I discuss how hormones from our gut, liver, pancreas and brain control our appetite--and the specific tools we can use to adjust those hormones in order to achieve specific goals. I explain the brain areas that control our desire to eat, and our desire to stop eating. I discuss a hormone we all can make that is regulated by UV-rays from sunlight that reduces our appetite. I also explain that when we eat controls our appetite and not the other way around (and how to leverage that fact). I describe how we are basically always eating until we reach a threshold level of fatty acids and amino acids in our gut and the factors that can alter that signaling and make us eat far more than we need. I also explain how insulin, glucose and glucagon work, why cholesterol is so key for ovary, adrenal, liver and testes function and how the ketogenic diet impacts glucose and thyroid levels. As always, I describe many tools: specific supplements, prescription compounds, specific types (and timing) of exercise to regulate hormones, specific timing and types of eating, ways to reduce sugar cravings by triggering release of the hormone CCK, and more. Note: A future episode will cover Thyroid hormone. Also, I mis-spoke when explaining POMC neurons. I said “P-M-O-C” but should have said “POMC”. Apologies. The name I gave for what POMC is, however, was correct: "proopiomelanocortin".

Folge vom 12.04.2021How to Optimize Testosterone & EstrogenIn 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.
