The skin plays an important role in thermoregulation and there is ample evidence that a cold environment can be a threat to the skin, because of the low human capacity for physiologic adaptation to cold and due to prominent seasonal changes, physiological, behavioral and other environmental factors. Usually, there is no serious skin damage until tissue freezing occurs. Frostnip is the mildest form of cold injury, whereas chilblains represent a more severe condition due to prolonged exposure to nonfreezing temperature and humidity. Trench foot, also known as immersion foot, occurs when the feet are wet, but not freezing, for long periods of time. Frostbite, the most serious peripheral cold injury, results in tissue necrosis, and usually occurs after exposure to freezing temperatures. The risk factors are represented by advanced age, substance abuse, mental impairment and injury. The main treatment recommendations include methods of rewarming, NSAIDs and use of topical corticosteroids.
