In cold weather, a winter scarf can warm more than just your neck. Wrapped around the nose and mouth, a scarf provides cover to help prevent chapped lips, runny noses and numb cheeks. When you're in the snow, wrapping a scarf over the nose and mouth helps prevent frostbite and sunburn. If you have asthma, extra protection from the scarf is a smart way to prevent an attack triggered by the cold air. In warmer months, a lightweight scarf covering the mouth and nose also helps stop the spread of germs from airborne viruses.
