Essentials: The Biology of Aggression, Mating & Arousal | Dr. David Anderson

Dr. Natalie Crawford, MD, is a double board-certified OB-GYN and reproductive endocrinologist. We discuss how to improve hormone health at any age and the importance of fertility markers not just for pregnancy, but as a powerful window into overall health, vitality and longevity. We discuss hormone replacement therapy, egg freezing, IVF, and what biomarkers like AMH really indicate. Plus, how anti-inflammatory diets and specific supplements can be beneficial and the impact of microplastics and certain fragrances on hormones. We also discuss lesser-known factors that deplete male and female fertility, vitality and health. This conversation highlights how better understanding of hormones and your reproductive markers can empower better informed choices at every stage of life. Read the show notes at hubermanlab.com.

Dr. Dacher Keltner, PhD, is a professor of psychology at the University of California, Berkeley, and a leading expert on the science of emotions and human connection. We discuss the science of awe—what evokes it and how to access it. Dr. Keltner explains how awe helps us frame our experience of life and who we are both as individuals and collectively. We also discuss the role of humor in social bonding, dispel common myths about the biology of emotions and review the lesser-known factors that strengthen or inhibit relationships and communities.

In this Huberman Lab Essentials episode, my guest is Dr. Andy Galpin, PhD, Executive Director of the Human Performance Center at Parker University and an expert in building strength and muscle size (hypertrophy). We cover the core principles and protocols for building strength and muscle, including science-based guidance on reps, sets, frequency and rest intervals. We also discuss how breathing and mental focus can enhance training and how post-workout downregulation can speed recovery. Read the show notes at hubermanlab.com.

Dr. Marc Breedlove, PhD, is a professor of neuroscience at Michigan State University and an expert on how hormones shape brain development and sexual orientation. We discuss how prenatal testosterone impacts whether someone is romantically attracted to men or women later in life, and what correlates of sexual orientation — such as finger-length ratios — tell us about the role of hormones in brain and psychological development. We also discuss why the number of older brothers a male has biases sexual orientation. Throughout, we explain how nature and nurture interact to shape male-female differences, behavior, and romantic partner choice.

In this Huberman Lab Essentials episode, I explain how salt (sodium) affects mental and physical performance, as well as cellular health. I describe how the brain monitors sodium levels to regulate thirst and fluid balance, and why salt needs can vary depending on activity level, stress, blood pressure, and diet. I also explain how to determine the right sodium intake for your individual needs and discuss why some people may benefit from increasing salt and other electrolytes.
