Deep dives
Deliberate cold and heat exposure can enhance human metabolism
Dr. Susanna Soberg's research focuses on the effects of deliberate cold and heat exposure on metabolism. Her studies have shown that exposing oneself to cold or heat can activate brown fat, increase metabolism, and improve insulin sensitivity. Deliberate cold exposure, such as cold showers or immersions, triggers a cold shock response, activating the sympathetic nervous system and releasing neurotransmitters like dopamine and norepinephrine. The activation of brown fat not only helps generate heat and increase metabolism but also has long-term benefits like lower blood pressure and improved insulin sensitivity.
