Doctors have developed a simple way in which people with Raynaud's disease can treat themselves at home, says Arthritis Today.

RD is a condition in which arteries in hands and feet go into spasms when subjected to cold temperatures.Doctors at the Army Research Institute of Environmental Medicine and the Lahey Clinic Medical Center in Massachusetts had a group of people with RD sit in a cold room with their hands in warm water. After 27 ten-minute sessions, the researchers found people's finger temperatures remained higher when they were exposed to cold and their RD symptoms were less frequent.
