Hypothermia
Hypothermia refers to an unintentional decrease in body temperature to below 95 F (35 C). It is a dangerous and potentially fatal condition but one which can be avoided with proper precautions. Although hypothermia can occur at temperatures above freezing, it is of most concern to the elderly and those with chronic diseases such as diabetes, when temperatures are near or below freezing (32 F, 0 C). For travelers coming to Utah, steps taken before leaving home can help prevent hypothermia. Plan to bring appropriate winter clothing, including extra protection for the hands, feet and the head. Bring clothes made of proper insulating materials: wool, polypropylene, treated polyester, down, etc. Cotton should be avoided. Plan to use a layering technique so clothing can be added to prevent chilling. See our winter dress page for layering suggestions. Many prescription drugs, including phenothiazines, tricyclic antidepressants, benzodiazepines and barbiturates, can predispose people to hypothermia. Your physician should be consulted at least several weeks before you leave home so that recommended changes can be made, if necessary. Once in Utah, there are several things one can do to prevent hypothermia. Dress properly for the conditions, as previously described, and move around as much as possible. Eating and digestion produce body heat. In cold weather, meals should be regular and snacks should be eaten frequently. Alcohol should be avoided because it lowers blood sugar levels and increases heat loss by dilating small blood vessels in the skin. |
