When working or exercising outside in cold weather, be alert for warning signs of frostbite: numbness, loss of feeling or a stinging sensation. Frostbite is most common on exposed skin, such as cheeks, nose and ears, but it can also occur on hands and feet. If you think you may have frostbite, get out of the cold and slowly warm the affected area without rubbing. If numbness continues, seek emergency care.
