Or, 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. Don't 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.
These procedures are not substitutes for proper medical care. Hypothermia is a medical emergency and frostbite should be evaluated by a health care provider. Knowing what to do is an important part of protecting your health and the health of others.
