When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Prolonged exposure to cold will eventually use up your body's stored energy. The result is hypothermia, or abnormally low body temperature. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is happening and won't be able to do anything about it.
Symptoms in Adults: shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness
Treatment: Treatment of mild hypothermia includes getting out of the cold or wet environment, using warm blankets, heaters, and hot water bottles. Moderate to severe hypothermia generally is treated in the hospital, where doctors can use special techniques to warm the core body temperature.
