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.
Time of exposure to cold is more predictive of lasting injury than temperature the individual was exposed to. The classification system of grades, based on the tissue response to initial rewarming and other factors is designed to predict degree of longterm recovery.
According to Mayo Clinic, the common cold is usually viral and resolved within a week to 10 days. Here are some symptoms according to the organization: Runny or stuffy nose.
Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects , by heat or cold, or by venoms and biotoxins .
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.
"In cold water, far more people die in a short period of time, not because of hypothermia -- they die because they drown, either because the first thing that happens in cold water, especially if ...
The culprit: a blast of cold Arctic air. The weather event kicks off meteorological winter , which starts on Dec. 1. Of course, astronomical winter begins on Dec. 21, the winter solstice .
