Dr. Elton Adams, a Great Falls, Montana, mountaineer and a physician who specializes in cold injuries, explains that upon exposure to cold, the body's initial response is to constrict the blood vessels near the skin, which directs more blood to the core, where it is needed for survival. Surface vessels re-dilate to flush warming blood into the hands and feet. Regardless of race, more women complain about cold sensitivity than men. That may be partly due to smaller body size, says Adams, but he points out that more women than men also suffer from Raynaud's disease. Don't smoke or chew tobacco.
Nicotine constricts the arteries in the extremities.
Avoid alcohol, which, contrary to folklore, actually acts to lower body temperature. Do see your doctor. Some prescription medications can improve circulation for Raynaud's patients by dilating blood vessels. Do wear gloves. He wears one pair or another nearly every day of the year.
