Hypothermia (From Wikipedia, the free encyclopedia)
Hypothermia (from Greek ὑποθερμία) is a condition in which core temperature drops below the required temperature for normal metabolism and body functions which is defined as 35.0 C (95.0 F). Body temperature is usually maintained near a constant level of 36.537.5 C (97.799.5 F) through biologic homeostasis or thermoregulation. If exposed to cold and the internal mechanisms are unable to replenish the heat that is being lost, a drop in core temperature occurs. As body temperature decreases, characteristic symptoms occur such as shivering and mental confusion.
Hypothermia is the opposite of hyperthermia which is present in heat exhaustion and heat stroke. One of the lowest documented body temperatures from which anyone has recovered was 13.0 C (55.4 F) in a near-drowning incident involving a 7-year-old girl in Sweden in December 2010.[1]
