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.

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

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.

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.

In this episode, my guest is Dr. Ellen Langer, Ph.D., professor of psychology at Harvard University and the world’s leading researcher on the mind-body connection and the power our thinking has on our physical health. She explains how specific ways of framing and asking questions about the world shape our physical health and rate of aging. Dr. Langer also explains how our perception of time and control significantly impact our rate of physical healing, hormones, immune system, and longevity. She describes mindfulness as a way of framing life, not simply a meditation or other practice, and discusses data showing how to use one’s mind to overcome health challenges and achieve remarkable outcomes. Dr. Langer is a luminary and pioneer in researching the relationship between the mind and body with scientific rigor. Her work and our discussion are applicable to women and men of all ages and walks of life.

In this Huberman Lab Essentials episode, I explain the biological mechanism behind motivation and drive, as well as discuss practical tools for overcoming procrastination. 

I discuss the key role dopamine plays in driving cravings and motivating action. I explain how dopamine regulates the balance between pleasure and pain, and what happens when this system becomes dysregulated, leading to addiction. I discuss the role of molecules like serotonin, which help enhance the enjoyment of the present, and explain how to balance the drive for more while staying focused in the present. I also discuss the causes of procrastination and describe strategies to boost dopamine levels through behavioral approaches or supplements. 

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.

In this Huberman Lab Essentials episode, I explain how the different nutrients and foods we eat impact our emotions and overall mood.

I discuss how the mind-body connection shapes our food choices and cravings, highlighting the roles of key neurotransmitters like dopamine and serotonin in driving eating behaviors. I explain the biological mechanisms behind cravings for specific foods, such as sugar, and how psychological factors like belief effects can influence our perception of hunger. I also describe how certain nutrients, like omega-3 fatty acids, and a healthy gut microbiome are crucial in mood regulation and immune function.

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.

In this episode, my guest is Dr. Brian Keating, Ph.D., a cosmologist and professor of physics at the University of California, San Diego. We discuss the origins of the universe and how humans have used light and optics to understand where and how life on Earth emerged.

We explore how early humans charted the stars, sun, moon, and other celestial events to measure time and track seasons, as well as how stargazing continues to connect us to a shared ancient experience. Additionally, we examine the scientific process, the practical and ethical challenges of pursuing groundbreaking discoveries, and the emotional toll of striving for recognition in one’s profession.

Finally, we discuss whether astrology has any scientific validity and consider the possibility of life beyond Earth.
