Allergic to cold weather?

Yes, it is possible to be allergic to the cold. In some people, cold temperatures trigger the release into the skin of histamines and other chemicals made by the immune system. The cause isn't clear. But some people appear to have overly sensitive histamine-containing skin cells.

Signs and symptoms of a "cold allergy" — also called cold urticaria — include:

• Skin redness
• Itching
• Hives (urticaria)
• Swelling

As much as possible, people with this condition should avoid exposure to cold air as well as cold water. For example, swimming in a cold lake could cause swelling over your whole body. If you think you have cold urticaria, consult your doctor. Treatment may include over-the-counter or prescription antihistamines taken before exposure to cold temperatures.
