When it gets hot, most of us hide indoors with the AC cranked, the workouts moved inside, and the thermostat parked at 72°F all summer long. But humans evolved in the heat, and the new science says we can still use it to get stronger, healthier, and (maybe most surprisingly) happier. In this episode, Michael Easter sits down with two of the best people in the world on the subject of heat.

Ashley Paulson, the Badwater 135 course record holder (a 135 mile race through Death Valley), finished in 21 hours and 44 minutes, beating the old record by 2.5 hours. She shares what 120°F at 11 p.m. actually feels like and the mindset that lets her thrive in it.

Then Bill Gifford, author of Hot Wired: How the Hidden Power of Heat Makes Us Stronger, talks about how your body adapts in 4 to 5 sessions of sauna treatment. Michael closes with a hydration playbook and the 1960s WHO research that nailed the perfect summer drink.
