On episode 740 of the 40+ Fitness podcast, we dive into the fascinating world of heat and its effects on health and fitness with renowned science journalist Bill Gifford, author of Hot Wired: How the Hidden Power of Heat Makes Us Stronger.
Together, we explore how heat is both a risk and a remarkable tool for healing and performance. From the dangers of heat exhaustion and heat stroke to the powerful health benefits of sauna, hot tubs, and other heat-based modalities, Bill shares the latest research and practical insights.
You'll learn why sweating is a sign of good health, how heat adaptation works, and how heat-based recovery can improve longevity and brain health. We'll also bust some myths about cold exposure, discuss the social aspects of sauna culture, and reveal simple strategies for embracing discomfort to become the healthiest, fittest, and happiest version of yourself.
