In this Huberman Lab Essentials episode, I explain how specific hormones influence both energy levels and the immune system and discuss practical tools for increasing energy throughout the day and managing stress.

I discuss the mechanism through which cortisol and epinephrine (adrenaline) impact the brain and body and why it’s important to regulate their levels, considering factors like time of day or stress levels. I also cover the positive benefits of short-term stress and behavioral protocols to increase energy and enhance stress resilience. Additionally, I explain how to optimize hormone levels through tools like sunlight exposure, meal timing, and supplements such as ashwagandha.

Huberman Lab Essentials episodes are approximately 30 minutes long and focus on key science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will continue to be released every Monday.

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.

Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday.

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.

Huberman Lab Essentials episodes are approximately 30 minutes long and focus on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, while our full-length episodes will continue to be released every Monday.

This Huberman Lab Essentials is from the full-length Huberman Lab episode, “How Our Hormones Control Our Hunger, Eating & Satiety.”

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.

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.

In this episode, my guest is Pavel Tsatsouline, a world-renowned strength and conditioning coach, former military special forces training instructor, author, and founder of StrongFirst—an online school focused on “low-tech, high-concept” training to build strength for men and women of all fitness levels.

We discuss the most effective and efficient ways to build strength, endurance, and flexibility. We cover bodyweight-only, free-weight, and machine-based protocols and describe training splits and lesser-known but highly effective ways to train, especially for people with limited time.

We also discuss local versus systemic nervous system and muscle recovery, how to complete training sessions with increased energy, why training to “failure” is not advised, optimal rest-between-sets protocols to improve performance, and how to vary effort levels across each week and month to ensure regular progress. This episode brings you highly practical, science-supported, and real-world-tested training methods to build strength, endurance, and flexibility from one of the world’s top experts.

In this Huberman Lab Essentials episode, I discuss the biology of emotions and moods, focusing on how development and neurochemicals shape our feelings and relationships.

I describe how early infant bonds and puberty shape adult patterns of emotional connection. I explain that understanding emotions requires recognizing both internal states and external cues, along with strategies to enhance your emotional awareness. Additionally, I discuss the key elements of healthy emotional bonds and provide practical tools to deepen one’s understanding of emotions, leading to a richer emotional life.

Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday.
