Essentials: Cold & Heat Exposure for Metabolic Health | Dr. Susanna Søberg

In this Huberman Lab Essentials episode, Dr. Susanna Søberg, a metabolic scientist, explains how deliberate cold and heat exposure improve metabolic health. She discusses brown fat activation, insulin sensitivity, and physiological resilience. Key topics include the cold shock response, shivering, the after-drop effect, and practical protocols for minimum effective doses of cold and heat. The Søberg Principle (ending with cold) is highlighted as a method to sustain metabolic benefits.
