In this episode of the Huberman Lab Essentials podcast, Dr. Andrew Huberman interviews Dr. Craig Heller about the effects of cold exposure on the body, particularly in relation to athletic performance. Dr. Heller explains the body's response to cold showers and ice baths, emphasizing the adrenaline shock and vasoconstriction. He differentiates between the benefits for aerobic and anaerobic activities, noting that cooling can increase the body's capacity to absorb heat during aerobic exercise. They discuss the importance of glabrous skin (hairless skin on palms, soles, and face) as primary sites for heat loss due to specialized blood vessels. The conversation covers practical strategies for cooling, such as avoiding tight grips during cycling and the potential benefits of pouring water on the head to cool the brain. Dr. Heller also shares a story about an NFL player who significantly improved his performance using palm cooling technology developed by Arteria (CoolMitt).
