In this episode of Everyday Health Stories, Anna and Dr. Reddy expand on the brain-focused benefits of sauna therapy explored in the previous episode, diving into the powerful, full-body effects of consistent heat exposure. They explain how sauna use not only lowers the risk of cardiovascular disease but also improves blood flow, enhances immune response by increasing white blood cell production, supports muscle repair through elevated growth hormone levels, and boosts metabolic health by improving insulin sensitivity and reducing inflammation. At the cellular level, heat activates protective heat shock proteins that stabilize damaged proteins, reduce oxidative stress, and promote overall longevity. The conversation is enriched by the story of British adventurer Ben Fogle, who credits his personal sauna practice with helping him recover from physically and mentally grueling expeditions. With insights into both traditional and infrared saunas, including Japan’s therapeutic Waon therapy, this episode presents sauna use as a time-tested, evidence-based, and remarkably accessible tool for total-body healing and resilience—one that can benefit almost anyone, from elite athletes to individuals managing chronic conditions.
