Essentials: Machines, Creativity & Love | Dr. Lex Fridman

In this Huberman Lab Essentials episode, I discuss interoception, the brain’s ability to sense and interpret signals from the body, which shapes our sense of self and underlies vital functions like focus, sleep, healing and emotions. I explain how the body communicates different types of information to the brain, influencing processes like digestion, heart rate and immune function. I also describe practical tools such as breathwork to regulate alertness, strategies to support gut health and reduce sugar cravings, and awareness practices to enhance interoception. By understanding and applying these tools, you can strengthen the brain-body connection to improve mood, overall health and performance. Read the episode show notes at hubermanlab.com.

My guest is Dr. Mary-Frances O’Connor, PhD, Professor of Clinical Psychology and Psychiatry at the University of Arizona and a world expert on the science of grief and loss. We discuss what happens in the brain and body when we grieve, the role of dopamine and yearning in the grieving process, the health risks of getting stuck at particular stages of grief and how to move through loss while also deeply honoring the person, animal or thing that is no longer with us. Dr. O’Connor explains that grief involves cycling back and forth between protest and despair (often guilt and anger too) and explains science-supported ways to move through that process in the healthiest possible way. Everyone experiences grief and loss at some point. Dr. O’Connor provides valuable knowledge and tools to help you navigate grief under any circumstance.

My guest is Dr. Melissa Ilardo, Ph.D., professor of biomedical informatics at the University of Utah. We discuss the interplay between genes and behaviors, including how certain behaviors can improve resilience by changing gene and organ function, as well as natural selection events happening in humans today. We also discuss the immune system–related reasons people find the smells of potential mates attractive—or not. We explore how physical and psychological traits are passed from one generation to the next, and the specific behaviors that can influence gene expression to improve health and performance. Melissa explains her lab’s pioneering research on breath-hold training and how activation of the dive reflex through breath holding can significantly improve oxygen availability by changing spleen size and function. We also delve into the medical uses and ethics of gene editing to cure disease in both babies and adults. For those interested in genes and inheritance, human performance, immune system function, and natural selection, this episode illustrates the remarkable interplay between human nature and nurture.

My guest is Tom Segura, renowned comedian, writer, actor and director. We discuss the “how-to” of comedy writing and storytelling, and what the science of humor and the creative process reveal about human emotion and memory. We explore why surprise and the act of "saying the unspoken truth" activate the brain’s reward circuits, as well as the subconscious mechanisms that shape our sense of what is funny. The episode also examines the bi-directional influence between comedy and cultural standards. It will interest anyone curious about the science of humor, the art of performance and emotional contagion. Read the episode show notes at hubermanlab.com.
