Cold Acclimation

Meaning

Cold acclimation refers to the physiological process by which the human body adapts to repeated or chronic exposure to low ambient temperatures. This adaptation results in altered thermoregulatory mechanisms, enhancing the body’s capacity to maintain core temperature and conserve energy. From a hormonal perspective, it is a potent modulator of the sympathetic nervous system and the endocrine system. The long-term effects of this process extend beyond simple temperature regulation, impacting metabolic health and potentially longevity pathways.
