Hypothermia is a medical condition characterized by an abnormally low core body temperature. When the body loses heat faster than it can generate it, the core temperature drops below normal physiological ranges, leading to systemic metabolic and enzymatic disruptions. The severity of the condition is determined by the degree of hypothermia, typically categorized by the measured temperature range. Treatment involves rewarming strategies, which can be physical, chemical, or circulatory, aiming to restore core temperature to a safe range while mitigating cardiac and neurological complications associated with prolonged cold exposure.
