Stress: The Science of Chilling Out
Sep 24, 2026 · 40m
Summary
Hosts Wendy Zuckerman and Meryl Horn explore the science of stress, revealing that moderate adversity can build resilience while chronic stress disrupts cortisol systems. They debunk viral vagus nerve stimulators, noting that free methods like slow breathing and exercise offer stronger evidence for regulation. Experts explain how reframing stress as a "challenge" rather than a threat can improve performance and reduce anxiety. The episode concludes with findings that interacting with living animals, not just textures, effectively lowers stress levels.
