Release of Norepinephrine
Cold water therapy, or cryotherapy, is linked to the release of norepinephrine, a neurotransmitter and hormone. Studies, such as one in the "Journal of Clinical Endocrinology & Metabolism" in 2001, have connected exposure to cold with increased norepinephrine levels, indicating activation of the sympathetic nervous system. This activation leads to heightened circulating norepinephrine, with its role in vasoconstriction redirecting blood flow during cold exposure. This process may contribute to improved mood, increased alertness, and potential metabolic effects.
