What Is Raynaud's Phenomenon?
Raynaud’s, sometimes referred to as Raynaud’s disease, syndrome or phenomenon, is a condition that causes a disruption in circulation to the hands. It is a relatively rare condition that affects the arteries that deliver blood throughout the body.
While you may be actively anticipating the cooler weather’s arrival, for some people, that cold weather leads to pain and circulatory distress. The body reacts to cold weather by adjusting blood flow. In some cases, that process malfunctions, and blood vessels constrict so much that they begin to spasm. This is known as vasospasm. When vasospasm occurs in the hands and feet due to exposure to cold, it is often due to a condition known as Raynaud’s disease.
