Fingers that change color when exposed to cold temperatures or stress are a sign of cyanosis, a bluish discoloration of the skin and mucous membranes due to lack of oxygen.

Avoid exposure to cold. Avoid wearing mittens or gloves while outdoors or when handling cold or frozen foods. Prevent chills that may follow any active recreational sport, wear roomy shoes and wool socks, and never go barefoot outdoors.

Raynaud’s phenomenon is a disorder that causes the blood vessels in the hands and feet to become narrower, thus decreasing blood flow. When this happens, parts of the body, usually the fingers and toes, become cold and numb, and change color (usually turning white or blue). Often, an attack or episode of these occurs from exposure to cold or stress.

Doctors do not know exactly why some people develop Raynaud’s phenomenon, but they understand that attacks often occur when people with this disorder are exposed to cold or are stressed.
