The Science & Health Benefits of Deliberate Heat Exposure

My guest is Dr. John Kruse, M.D., Ph.D., a psychiatrist specializing in treating people with attention-deficit/hyperactivity disorder (ADHD). We discuss the many stimulant and nonstimulant ADHD medications available, covering both their potential benefits and risks. We also explore behavioral approaches to managing ADHD, the key role of maintaining a consistent sleep-wake schedule, and the impact of exercise, fish oil supplementation, and video games on ADHD. Additionally, we examine the genetic and environmental factors contributing to the rise in adult and child ADHD diagnoses and offer various options to consider if you or someone you know is struggling with focus.

In this Huberman Lab Essentials episode, I explain how two key hormones control metabolism and discuss tools to enhance their levels to improve metabolic health. I discuss the pathways through which the brain and body interact to produce thyroid hormone and growth hormone, and how these hormones influence essential processes like tissue growth and repair, body composition, and energy production. I explain how thyroid hormone levels are influenced by key nutrients, such as iodine, selenium, and L-tyrosine. I also explain how practices such as exercise, sleep, meditation and sauna can offset age-related declines in growth hormone, to optimize overall hormone health and metabolism.

My guest is Dr. Richard Schwartz, Ph.D., therapist, author, and founder of Internal Family Systems (IFS) therapy. We discuss how IFS views the mind as a collection of parts, each shaped by different life experiences—both good and bad, including trauma. To demonstrate how IFS works, Dr. Schwartz guides Dr. Huberman and you, the listener, through an example IFS session. We also explore how IFS and body awareness can help break harmful thought and behavior patterns, promote emotional healing, and build healthier relationships.

In this Huberman Lab Essentials episode, I explain how hormones regulate hunger, appetite and feelings of satiety (fullness), along with strategies to help control appetite. I describe how the body senses nutrient levels and how the brain processes these signals to stimulate hunger or suppress appetite. I also discuss how certain foods can help curb hunger, while processed foods and emulsifiers can interfere with satiety signals, leading to overeating. Additionally, I cover how lifestyle factors such as exercise and meal timing regulate blood glucose levels, which in turn impact hunger and appetite.

In this Huberman Lab Essentials episode, I explain how to optimize hormones—particularly testosterone, estrogen, and related sex steroids—to enhance fertility and overall well-being. I discuss the sources of testosterone and estrogen and how their levels fluctuate with age in both males and females. I also cover how behaviors such as exercise, cold and heat exposure, light exposure, illness, and breathing patterns affect hormones. Additionally, I examine specific supplements and replacement therapies, highlighting important precautions to consider when adjusting hormone levels.

My guest is Dr. Michael Platt, Ph.D., a professor of neuroscience and psychology at the University of Pennsylvania. We discuss how factors such as hormonal or social status influence what we value, how we make decisions, and even our perceptions across a range of areas, from who and what we find attractive to our political affiliations. We also discuss how humans evaluate and shift power in relationships and form hierarchies in groups. Dr. Platt also shares new science-based tools for improving focus, creativity, and attention.

In this Huberman Lab Essentials episode, I explain the crucial role hormones play in shaping the sexual development of both the brain and body. I discuss how biological masculinization and feminization depend on factors such as genetics, hormone ratios, and receptor availability. I also explore how hormones like testosterone, estrogen, and other steroid hormones influence sexual characteristics and brain development. Additionally, I examine the impact of environmental factors—such as herbicides like atrazine, cannabis, alcohol, and even cell phones—on hormone function and reproductive health.
