Background
Hypothermia (hi-po-THUR-me-uh) is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. The term “hypo” refers to less, and “thermia” refers to temperature. Normally, the core body temperature is 98.6 degrees F. Hypothermia occurs as your body temperature passes below 95 F (35 C). When your body temperature drops, your heart, nervous system and other organs cannot work correctly. Left untreated, hypothermia can eventually lead to severe heart and respiratory failure, and in some cases, death. Hypothermia is most often caused by long term exposure to cold weather or or and unexpected immersion into in the face of a cold stressor. Hypothermia,

In the 1950s, Doctor Rosomoff demonstrated the positive effects of mild hypothermia in dogs, after incurring brain ischemia and traumatic brain injury.[3] In the 1980s, further animal studies indicated the ability of mild hypothermia to act as a general neuroprotectant following a blockage of blood flow to the brain. In 1999, following a skiing accident Anna Bågenholm's heart stopped for more than three hours and her body temperature dropped to 13.7C, prior to being resuscitated.[4] In addition to the animal studies and Anna Bågenholm's accident, two landmark human studies were published simultaneously in 2002 by the New England Journal of Medicine.[1] Both studies, one occurring in Europe and the other in Australia, demonstrated the positive effects of mild hypothermia applied following cardiac arrest.[2] Responding to this research, in 2003 the American Heart Association (AHA) and the International Liaison Committee on Resuscitation (ILCOR) endorsed the use of therapeutic hypothermia following cardiac arrest.[5] Currently, a growing percentage of hospitals around the world incorporate the AHA/ILCOR guidelines and include hypothermic therapies in their standard package of care for patients suffering from cardiac arrest.[1] Some researchers go so far as to contend that hypothermia represents a better neuroprotectant following a blockage of blood to the brain than any known drug.[1][6] Over this same period, a
