Frostbite is a localized lesion caused by the direct action of the cold during exposure, of varied length, to temperatures below 32°F (0°C).

It is distinguished from chilblains and trench feet, which occur at temperatures above 32°F (0°C) in a humid environment, and “acrosyndromes” (peripheral vascular diseases), which are microcirculatory or rheumatic diseases.
