Wear cotton and wool. Wool provides excellent insulation while allowing the skin to breathe. Natural cotton is kind to skin. When worn under a layer of wool, cotton can keep you warm and comfy. Keep the air in your home moist.
Some people use humidifiers in the winter.
Hot water tends to rob the skin of moisture. This helps to retain the moisture from the bath or shower. Perfumed lotions are less effective than those without perfume. Don't use soap or lotions that contain alcohol. Alcohol dries the skin.
