Abstract

Introduction Hypothermia is defined as a core temperature below 35°C. The body responds acutely to cold by increasing muscle tone, shivering, vasoconstriction, and behavioral changes. In addition, the hypothalamus increases TSH production causing an increased metabolic rate. In healthy patients, the body’s compensatory mechanisms are overwhelmed by exposure. Age, health, nutrition, intoxication and medications can interfere with adequate thermoregulation. The human body produces approximately 250 joules (60 kcal) per m2 of body surface area per hour.
