Essentials: Benefits of Sauna & Deliberate Heat Exposure

In this Huberman Lab Essentials episode, I discuss the mechanisms through which deliberate heat exposure enhances both physical and mental health. I outline specific protocols for deliberate heat exposure, including recommended temperature ranges, frequency, timing, duration and sauna alternatives. In addition, I explain how to tailor your heat protocols to support your specific goals, such as increasing growth hormone, reducing cortisol or supporting cognitive health.

Dr. Alex Marson, MD, PhD, is a Senior Investigator at the Gladstone Institutes and a professor of medicine at the University of California, San Francisco. We discuss the biology of the immune system and cancer, and everyday choices that can increase or decrease your cancer risk, several of which are surprising but all of which are actionable. We also discuss immunotherapy, including how engineered T-cells can be used to defeat childhood and adult cancers. Dr. Marson explains CRISPR and gene editing to cure diseases, and we address the ethical questions surrounding gene editing in embryos, children and adults. This discussion is for anyone interested in avoiding cancer and/or seeking to understand the science and practical applications of immune- or gene-therapy. Read the show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, my guest is Dr. Charles Zuker, PhD, a professor of biochemistry, molecular biophysics and neuroscience at Columbia University and an Investigator with the Howard Hughes Medical Institute (HHMI). We explore taste perception and how the brain transforms chemical signals from food into distinct taste experiences. We discuss how these taste signals shape both conscious choices and unconscious behavior, as well as how food preferences can change over time. Additionally, we discuss gut–brain signaling and explain why sugar is especially powerful at driving cravings. Read the episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explore how different wavelengths of light affect the human body and how light exposure can improve sleep quality, mood and daytime alertness while supporting healthy hormone regulation. I also discuss the therapeutic use of ultraviolet and infrared/red light for a wide variety of benefits, including improved skin health and offsetting age-related vision loss. I explain the biological mechanisms behind these light-based therapies and offer practical tools that listeners can use to improve both their mental and physical well-being.

Dr. Tony Wyss-Coray, PhD, is a professor of neurology at Stanford School of Medicine and Director of the Phil and Penny Knight Initiative for Brain Resilience who is discovering factors present in young blood and in exercised blood that can improve brain, heart, and other organ health. We discuss how different organs age at different rates and how to accurately measure biological aging. We also discuss the specific proteins found in blood when we are young and that are increased by things such as exercise, sunlight exposure, short-term fasting, specific foods, and social connection that can significantly increase vitality, restore youthful functioning of the brain and body, and potentially increase lifespan.

Dr. Lauren Colenso-Semple, PhD, is an expert in the science of strength and muscle building and nutrition. She explains the most effective resistance and cardiovascular training programs for women and if and how those programs should differ from those followed by men. She explains program design options, exercise selection, sets, repetition ranges, rest periods, if you need to train to failure and much more. We discuss the relevance of menstrual cycles, (peri)menopause, birth control, body frame differences, as well as best practices for nutrition, hormone replacement and supplementation. Throughout the episode Dr. Lauren Colenso-Semple dispels common myths about women's fitness and nutrition such as the impact of fasting, cortisol, weight vests and more. This episode provides a masterclass in the best science-supported fitness and nutrition programs for women and for men.
