Why Heat Makes You Stronger (Backed by Science) | A Conversation with Bill Gifford, author of "Hotwired: How the Hidden Power of Heat Makes Us Stronger" | Sauna Talk Episode 129

In this episode of Sauna Talk, Glenn sits down with Bill Gifford, author of Hotwired: How the Hidden Power of Heat Makes Us Stronger, for a wide-ranging conversation on sauna, heat adaptation, and the connection between physical challenge and mental well-being. Bill shares how his journey into heat began through personal stress, scientific curiosity, and his reporting on the powerful effects of sauna and thermal exposure. Together, Glenn and Bill explore the famous Finnish sauna research of Dr. Jari Laukkanen, the role of heat in cardiovascular and mental health, and the way sauna can act as both a physiological reset and a social connector. They also dive into Bill's experience training for the brutal Hotter Than Hell 100, what heat adaptation teaches us about resilience, and why sauna offers something much bigger than simple recovery. From neurotransmitters and stress relief to friendship, veterans' healing, and the culture of bathing, this episode shows how heat can make us stronger in body, mind, and spirit.
