Frostbite is an injury to the body caused by freezing.
Most often, frostbite affects the nose, ears, cheeks, chin, fingers, or toes, and can permanently damage the body, even leading to amputation in severe cases. The risk of frostbite is increased in persons with reduced blood circulation, those with constriction of blood flow because of gloves or boots that are too tight, and in persons not dressed for extremely cold temperatures. Exposed hands and feet are the most vulnerable. The following are the most common symptoms of frostbite. However, each individual may experience symptoms differently.
