O.3.4.1.2 At or below 0 °C (32 °F), the body automatically takes action to preserve its core temperature and to combat hypothermia. Blood vessels close to the skin start to constrict and blood is shifted away from the extremities. In extreme cold, or when the body is exposed to cold for long periods, this protective strategy can reduce blood flow in some areas of the body to dangerously low levels. This lack of blood can lead to the eventual freezing and death of skin tissue in the affected areas.The same factors that can lead to hypothermia (e.g. long exposure to cold; extreme cold; O.3.4.1.3 inadequate clothing; wet clothes; wind chill) can also contribute to frostbite, as can inadequate blood circulation caused by factors such as tightly fitting clothing, gloves or boots; cramped positions; fatigue; certain medications; smoking; alcohol use; or diseases that affect the blood vessels, such as diabetes and Raynaud’s disease.O.3.4.2Signs and symptomsO.3.4.2.1 General
