People who are trained in biofeedback can use this technique along with warming the hands or feet in water to help lessen the attack. In cold weather, people with Raynaud's phenomenon must pay particular attention to dressing. Several layers of loose clothing, socks, hats, and gloves or mittens are recommended. A hat is important because a great deal of body heat is lost through the scalp. Feet should be kept dry and warm.
Some people find it helpful to wear mittens and socks to bed during winter.
Chemical warmers, such as small heating pouches that can be placed in pockets, mittens, boots, or shoes, can give added protection during long periods outdoors. People who have secondary Raynaud's phenomenon should talk to their doctors before exercising outdoors in cold weather. People with Raynaud's phenomenon should also be aware that air conditioning can trigger attacks. Turning down the air conditioning or wearing a sweater may help prevent attacks. Some people find it helpful to use insulated drinking glasses and to put on gloves before handling frozen or refrigerated foods.
