Symptoms Of Raynaud's Disease

Skin Color Changes Due To Cold & Stress

With Raynaud's disease, the skin color changes to cold and stress due to reasons similar to why certain body parts become cold. The arteries in nonvital areas constrict to keep blood and oxygen supplied to areas needed to sustain life. The coldness and lack of blood also tend to cause the skin to change colors. In some cases, the skin will turn pale or white, and in other cases, the skin will turn blue or purple. The color change is, in part, due to a lack of warmth to the affected areas. The lack of oxygen to those areas also contributes to the color change. Usually, the natural color of the skin returns shortly after the cold or the stress is removed. If it takes a long time or persists, Raynaud's disease may have an underlying cause.
