What is a common sign of frostbite?

A common sign of frostbite is white, waxy skin. This occurs because the extreme cold causes blood vessels to constrict, reducing blood flow to the affected area. As the skin loses warmth and moisture, it can become pale or white and may appear waxy. This change in skin color is particularly indicative of frostbite and serves as an important cue for recognizing the severity of the condition. Typically, frostbite can affect fingers, toes, the nose, and ears, where the skin might display this characteristic appearance. Recognizing this sign allows for timely intervention to prevent further tissue damage and complications.
