Know the signs: frostbite & hypothermia
Warning sings of hypothermia, an abnormally low body temperature, include shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness. The health department says if you detect these symptoms in a person, get them into a warm room and remove any wet clothing. Warm the center of the body first with an electric blanket, if possible. If not, use skin-to-skin contact under loose, dry layers of blankets, clothes, towels, or sheets. A warm beverage can help increase body temperature, but do not use anything alcoholic.
Warning signs of frostbite, an injury to the body caused by freezing, include redness or pain in any skin area, white or grayish-yellow skin, skin that feels unusually firm or waxy, and numbness. If you discover someone displaying these symptoms, get the victim into a warm room and immerse the affected area in warm – not hot – water. Do not rub the frostbitten area or massage it, as this may cause more damage. Do not use a heating pad, heat lamp, or the heat of a stove, fireplace, or radiator for warming, as frostbitten areas are numb and can be easily burned.
In both cases, seek medical attention immediately.
