When in a cold environment, most of your body's energy is used to keep your internal temperature warm. Over time, your body will begin to shift blood flow from your extremities (hands, feet, arms, and legs) and outer skin to the core (chest and abdomen). This allows exposed skin and the extremities to cool rapidly and increases the risk of frostbite and hypothermia. Combine this with cold water, and trench foot may also be a problem.

Hypothermia Hypothermia is an abnormal and dangerous condition in which the temperature of the body is below 95 degrees Fahrenheit (35 degrees Centigrade). Hypothermia is usually caused by prolonged exposure to cold. When more heat is lost than the body can generate, hypothermia can result. Common causes include:

Falling overboard from a boat into cold water

Being outside with an uncovered head in winter

Wearing wet clothing for a prolonged period of time in windy weather, heavy exertion, or poor fluid or food intake. This can also cause hypothermia even in above-freezing temperatures.

The onset of symptoms is usually slow; there is likely to be a gradual loss of mental acuity and physical ability. The person experiencing hypothermia, in fact, may be unaware that he or she is in a state that requires emergency medical treatment. Symptoms include:

Apathy or lethargy. Confusion. Drowsiness. Loss of coordination. Pale and cold skin. Shock Slowing of breathing. Slurred speech.
