In this Huberman Lab Essentials episode, I discuss the mechanisms through which deliberate heat exposure enhances both physical and mental health. I outline specific protocols for deliberate heat exposure, including recommended temperature ranges, frequency, timing, duration and sauna alternatives. In addition, I explain how to tailor your heat protocols to support your specific goals, such as increasing growth hormone, reducing cortisol or supporting cognitive health.
