Other cold-related injuries that can be present either alone or in combination with hypothermia include: Chilblains: condition caused by repeated exposure of skin to temperatures just above freezing. The cold causes damage to small blood vessels in the skin. This damage is permanent and the redness and itching will return with additional exposure.
"Assuming that everybody responds the same way to cold is extremely dangerous," said François Haman, a health science professor at the University of Ottawa in Canada who has studied cold exposure ...
Exposure to the cold causes your body to lose heat more quickly than it can produce heat, causing you to use up your heat stores and your body temperature to drop, according to the Centers for ...
Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).
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.
As with heat, cold exposure and immersion can trigger a psychological high, Haman says. “You actually feel good once you come out of the cold,” he tells Fortune .
It does not require exposure to cold to develop. Levamisole toxicity is a vasculitis that can appear similar to frostbite. [18] It is caused by contamination of cocaine by levamisole. Skin lesions can look similar those of frostbite, but do not require cold exposure to occur. People who have hypothermia often have frostbite as well. [10]
“Cold hands from benign causes are usually of a short duration, and easily reversible when the triggering condition such as stress or exposure to low temperature abates,” Ogunwale explains.
