About White fingers
Turning white fingers is an indication that you are feeling very cold. But in some the white fingers are dramatic on exposure to cold. Normally when exposed to cold there is a slowing of blood flow to fingers and toes, as small arteries in the extremities narrow down reducing blood flow and preserving the core body temperature. Also known as ‘Raynaud’s Disease’, in people with white fingers the response is exaggerated for no particular known reason. The constriction, called vasospasm, can last from anywhere between a few minutes to several hours. Although the constriction happen in the fingers and toes, but at times the nose, ears and cheek can be affected too. In people with ‘Raynaud’s Disease’, stressful emotions can also trigger vasospasm.
