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.
Cold and flu season always comes around when the weather starts to change. But does cold, wet weather actually make you sick?Not really, experts say. But cooler temperatures and dry winter air can ...
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.
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.
The mainstay of cold treatment is to manage the symptoms,” Dr. Agyemang says. She recommends cough suppressants and decongestants to help with coughing and a stuffy nose, common cold symptoms.
An experiment has shown cold acclimation minimizes the hunting reaction (reduced mean temperature of the digits and a prolonged time of cold exposure prior to initial vasodilation), thus putting the hand at a greater risk of cold injury when it is exposed to cold. [2]
