Hypothermia means low heat; it is the condition of an abnormally low body temperature. It occurs when the body is exposed to severe cold, and loses heat faster than it can be replaced. As a result, the core body temperature drops below 95ºF, and it affects the brain, heart, lungs, and other vital organs. Older
people are more susceptible to hypothermia because they do not tolerate cold as well as younger adults.

Hypothermia can be caused by exposure to cold air or water. Certain health problems, such as diabetes, can make hypothermia more likely. Often, an older adult will have no feeling that he or she is cold. Be alert for symptoms such as: shivering; slow, slurred and incoherent speech; memory lapses, disorientation, and poor judgment; mottled or pale skin; weakness, fatigue, and drowsiness; a weak irregular pulse, with a depressed respiratory rate; and lethargy.

Hypothermia can occur even in temperatures well above freezing–even indoors; it can range in severity from mild to life-threatening. The presence of wind and water can speed cooling–and increase the risk of hypothermia. 1. Make sure that you wear layers of warm clothing in cool or cold weather. Do this even if you don’t feel cold. 2. Dress properly when you go outside (wear a sweater, hat, scarf, gloves, and warm socks when going out in the cold). 3. Set the thermostat no lower than 68ºF–higher if your health care provider advises it. 4. Keep an eye on your exact body temperature by having a clinical thermometer with you. Death can occur if the body temperature falls below 93.2ºF. Get emergency help if you suspect hypothermia.

Like the heat, the cold can cause special concerns for older people. The body’s ability to maintain a constant internal temperature decreases with age. If you would like to engage in any outdoor activity, avoid prolonged exposure to cold weather. Adopt these habits: drink plenty of fluids; eat regularly; and avoid alcohol, cigarettes and caffeine.
