Frostbite is dangerous and can often happen quickly, depending on both the temperature and wind chill factor. Here’s how to know if it’s frostbite and how to treat it.
Frostbite is a skin injury that occurs when someone is exposed to extremely low temperatures, causing the freezing of the skin or other tissues, [1] commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. [6] Most often, frostbite occurs in the hands and feet.
Just as heat stroke has the first stage of heat exhaustion, frostbite has a first stage called "frostnip," which occurs when skin is exposed to the cold, usually when temperatures are.

Affected skin becomes numb, turns white or blue, and develops blisters. [1] Frostnip is a superficial skin injury that won't freeze the skin or cause long-term damage. [8] Frostbite involves freezing of fluids inside and outside of cells that results in cell breakdown, electrolyte imbalances, and inflammation. [8]
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
Forecasters say the risk of developing frostbite and hypothermia increases as the wind chill temperature falls. Hypothermia occurs when the body’s stored energy is used up, causing its ...
Autoamputation could be the result of severe cases of certain chronic wounds, such as frostbite. These chronic wounds might be due to some vascular and pathogenic conditions [4] like Buerger disease or Reynaud's phenomenon. Also, uncontrolled diabetes can predispose one to autoamputation. [4] However, autoamputation has been described as ...
