Show Notes
In this Huberman Lab Essentials episode, my guest is Dr. Susanna Søberg, PhD, a metabolic scientist who trained at the University of Copenhagen and an expert in the effects of cold and heat exposure on human health. Dr. Søberg explains how brief, deliberate cold exposure improves insulin sensitivity, promotes metabolic health and physiological resilience. We also discuss the cold shock response and shivering, along with practical guidance on temperature, duration, and sequencing cold and heat exposure for optimal benefits.
