Hypothermia is a condition in which an organism's temperature drops below that required for normal metabolism and body functions. In warm-blooded animals, core body temperature is maintained near a constant level through biologic homeostasis or thermoregulation. However, when the body is exposed to cold, its internal mechanisms may be unable to replenish the heat that is being lost to the organism's surroundings. Extended exposure leads to death....

Hypothermia is a condition in which an organism's temperature drops below that required for normal metabolism and body functions. In warm-blooded animals, core body temperature is maintained near a constant level through biologic homeostasis or thermoregulation. However, when the body is exposed to cold, its internal mechanisms may be unable to replenish the heat that is being lost to the organism's surroundings. Extended exposure leads to death.
Hypothermia is the opposite of hyperthermia which is present in heat exhaustion and heat stroke.
Hypothermia is defined as any body temperature below 35.0 °C (95.0 °F). It is subdivided into four different degrees, mild around 32–35 °C (90–95 °F); moderate, 28–32 °C (82–90 °F); severe, 20–28 °C (68–82 °F); and profound at less than 20 °C (68 °F). This is in contrast with hyperthermia or fever which is defined as a rectal temperature of greater than 37.8 °C (100.0 °F). Other cold-related injuries that can either present alone or in combination...
