Frostbite is a tissue injury induced by exposure to cold. Frost bite happens when a person is exposed to extreme cold leading to damage of the skin and the underlying tissue. Any part of the body may be affected by frostbite but it usually occurs in the nose, ears, fingers and toes.

When the temperature reaches zero or below, the blood vessels located close to the skin start to constrict to decrease the blood flowing throw them which in turn will lead to decrease heat loss and preserve core body temperature (see regulation of body temperature). When the skin and the underlying tissues are exposed to prolonged cold or extreme cold, the flow of blood to the affected areas will be greatly reduced leading to damage to these areas which may be permanent leading to tissue death and amputation in severe cases.

The risk of frostbite increases in the following:
