Cold Injury

Cold injury (pronounced: /koʊld ˈɪndʒəri/) is a type of tissue damage caused by exposure to extreme cold temperatures. The term encompasses a range of conditions including frostbite, hypothermia, and non-freezing cold injury.

Etymology

The term "cold injury" is derived from the English words "cold", meaning low temperature, and "injury", meaning harm or damage.

Types of Cold Injury

Frostbite (pronounced: /ˈfrɔːstbaɪt/): This is the most severe form of cold injury, where the skin and underlying tissues freeze. It typically affects extremities like the fingers, toes, nose, ears, cheeks, and chin.

Hypothermia (pronounced: /ˌhaɪpərˈθɜːrmɪə/): This is a potentially dangerous drop in body temperature, usually caused by prolonged exposure to cold temperatures.

Non-freezing cold injury (pronounced: /nɒnˈfriːzɪŋ koʊld ˈɪndʒəri/): This includes conditions like trench foot and chilblains, which are caused by prolonged exposure to cold, wet conditions above freezing point.

Related Terms

Chilblains (pronounced: /ˈtʃɪlbleɪnz/): These are the painful inflammation of small blood vessels in your skin that occur in response to repeated exposure to cold but not freezing air.

Trench foot (pronounced: /trɛntʃ fʊt/): This is a non-freezing cold injury that occurs when feet are cold and wet for a long period of time.

Frostnip (pronounced: /ˈfrɔːstnɪp/): This is a mild form of frostbite, where only the skin freezes.
