@susanna_soeberg: A head dunk in cold water is unnecessary for the physiological benefits of cold exposure. ❄️ Most of the adaptation happens through receptors on your skin, your core temperature drop, and your nervous system’s response — not through submerging your head. Head immersion increases heat loss dramatically, can trigger headaches, and adds stress without increasing the metabolic or brown fat benefits. You get the full effect by keeping your body in the water and your breathing steady — no head dunk required. I explain the physiology behind this in Episode 4 of The Reset Lab Podcast.
