Frostbite

Frostbite is an injury to the body that is caused by freezing. Frostbite causes a loss of feeling and color in affected areas, and most often affects the nose, ears, cheeks, chin, fingers or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation.

At the first signs of redness or pain in any skin area, get out of the cold or protect any exposed skin. Any of the following signs may indicate frostbite: a white or grayish-yellow skin area, skin that feels unusually firm or waxy, or numbness. A victim is often unaware of frostbite until someone else points it out because the frozen tissues are numb.

If you detect symptoms of frostbite, seek medical care. If immediate medical care is not available, proceed as follows:

  • Get into a warm room as soon as possible.
  • Unless absolutely necessary, do not walk on frostbitten feet or toes; this increases the damage.
  • Immerse the affected area in warm, but not hot, water. The temperature should be comfortable to the touch for unaffected parts of the body. Alternatively, warm the affected area using body heat. For example, the heat of an armpit can be used to warm frostbitten fingers.
  • Do not rub the frostbitten area with snow or massage it at all. This can cause more damage.
  • Do not use a heating pad, heat lamp, or the heat of a stove, fireplace or radiator for warming. Affected areas are numb and can be easily burned.
