What causes cold hands and feet?
Humans are tropical animals. We are adapted to a warm climate. When exposed to cold, the body tries to stay warm. If the body is cooling off, circulation decreases in the arms, legs, ears, and nose so that the rest of the core body can stay warm. When temperatures are below freezing, ice may form in these areas with less circulation.
- Nonfreezing cold injuries are also caused by cooling of the skin. In immersion injuries, the nerves and blood vessels are damaged after exposure to cold, wet conditions at or above freezing temperatures.
- Pernio is caused by exposure to cold for a long period of time without freezing or by very wet conditions.
- Raynaud’s phenomenon is an abnormal narrowing of the blood vessels that constrict with cooling of the fingers or toes.
- Cryoglobulins are proteins, which are normally dissolved in the blood, that become solids or gels when cold. Cryoglobulinemia is the condition associated with cryoglobulins in the blood, whereby cold exposure leads to bluish discoloration of the fingers or toes.
- The formation of hives in response to cold exposure of the skin is called cold urticarial
A list of diseases that cause cold hand and feet include:
- Raynaud”s Disease
- Buerger”s Disease
- Thyroid Disease
- Poor circulation
- Nervous system disorders

Diagnosis & Treatment

How is cold hands and feet diagnosed?
Frostbite is diagnosed by the way it looks, not by tests. There are no specific tests for other conditions caused by cold, except blood tests for cryoglobulins. As with frostbite, testing may be needed for other injuries or conditions.
If there are other injuries such as hypothermia (below normal body temperature) or possible broken bones, tests may be needed for the other injuries.
If the frostbite seems severe, a bone scan may be necessary. This is a painless procedure that shows the doctor which areas of the hands or feet still have circulation.
Other tests often done for frostbite include blood tests, especially tests of the tendency of the blood to clot, and X-rays.
How is cold hands and feet treated?
If you come to the emergency department and still have any white areas of frostbite, the doctor will begin rapid rewarming in water that is slightly above body temperature. The frozen parts are thawed until they are pink, which shows that the circulation has returned.
If the warmed area is only a little red, you may be allowed to go home with instructions about how to protect the injured area. If you have only clear blisters that go to the ends of the fingers and toes along with swelling and some pain, you may also be allowed to return home with instructions. If you have dark blisters, no swelling, or no circulation in the warmed area, you will be hospitalized.
In either case, you may be asked to take aspirin or ibuprofen (Advil), which may protect against further injury to the area from substances that are released from damaged cells. You may also be given other medications to help the circulation of blood and to assure good nutrition.
If you are hospitalized, the injured areas will be wrapped most of the time and elevated. Twice a day they will be unwrapped and placed in a whirlpool to remove bacteria and dead cells that build up on the surface of the skin. If frostbite is severe, it may be necessary to remove some of the dead areas by amputation.
