Abstract:Frostbite or cold burn is the medical condition in which localized damage is caused to exposed skin and subcutaneous tissue due to freezing. Frostbite most likely involves body parts farthest from the heart and those with large exposed areas. At or below 0 °C (32 °F), blood vessels close to the skin start to constrict, and blood is shunted away from the extremities via the physiological feedback action of glomus bodies. This peripheral vasoconstriction helps to conserve core body temperature. In extreme cold, … Show more
