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.
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 often preceded by frostnip. [12] The symptoms of frostbite progress with prolonged exposure to cold. Historically, frostbite has been classified by degrees according to skin and sensation changes, similar to burn classifications. However, the degrees do not correspond to the amount of long term damage. [13]
As frigid air makes contact to exposed skin, it leads nerves and blood vessels just below the top layer of skin to freeze. Rain, snow and wind can cause the skin to cool faster and lead to frostbite.
frostbite and hypothermia 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 ...
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]
Non-freezing cold injuries (NFCI) is a class of tissue damage caused by sustained exposure to low temperature without actual freezing. [1] There are several forms of NFCI, and the common names may refer to the circumstances in which they commonly occur or were first described, such as trench foot, which was named after its association with trench warfare.
Frostbite in dogs is a serious condition. It occurs when the skin and underlying tissues are exposed to freezing or extremely cold temperatures for a prolonged period of time.
