Extreme Cold (Hypothermia) 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. Hypothermia is most likely at very cold temperatures, but it can occur even at cool temperatures (above 40ï¿½F)
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.
Epidemiology: Varies widely depending on location and season. Estimates are difficult to quantify as hypothermia is often listed as a secondary diagnosis. 0.3/100,000 deaths from primary hypothermia. Extremes of age (young children and the elderly) are the most vulnerable to hypothermic injury. Adults have highest probability of being exposed to hypothermic conditions. Males more affected than females. In urban populations of the U.S., most cases of hypothermia are due to homelessness, mental illness, or illicit drug and/or alcohol use. Outdoor workers are at increased risk.
