Do you dread shaking hands with people because your hands are always cold? Have your fingers or toes ever turned white or blue? If so, you may have a disorder known as Raynaud’s (ray-NOHZ).

According to the Raynaud’s Association, Raynaud’s is a disorder that affects about 5-10% of the U.S. population and is more common in women than in men. Raynaud’s causes vasospasms, a narrowing of the blood vessels in response to cold temperatures or stress.
