Frostbite ii an important health hazard each winter in most parts of the country.
Today’s Health, the magazine of the American Medical Association, reports that true frostbite means that the tissues are frozen. Crystals of ice form between the cells. Nerves, muscles and blood vessel tissues are most susceptible.
Frostbite can happen before you know it, and it isn’t necessary for the temperature to be excessively low. The wind plays an important role. The chilling effect of air at 20 degrees moving at 45 miles an hour is the same as 40below-zero air on a still day.
One of the dangers of frostbite is that you often don’t feel it. First thing you know is that someone else notices that your ear or nose is turning white. The frozen part becomes hard to touch and loses feeling. Many sports leaders advocate a buddy system for outdoor winter sports: two persons are paired off, each watching the other for signs of frostbite.
To prevent frostbite, first be certain that you sme properly dressed for the temperature. Avoid overexertion and excessive perspiration. Avoid contact of bare flesh with cold metal. Don’t drink alcohol or smoke.
In first aid for frostbite, forget the old saw about rubbing
