In this Huberman Lab Essentials episode, I discuss the critical role of temperature regulation in optimizing athletic and physical performance. I explain why overheating can hinder performance and endurance and how techniques like palmar cooling can help extend physical effort by aiding temperature regulation. I also highlight how specific body areas, such as the palms and face, are key targets for regulating temperature, allowing heat to dissipate efficiently. Lastly, I discuss how temperature can support training recovery while cautioning that extreme cold, such as ice baths immediately after training, can block adaptations.
