Protect skin. Exposure to harsh weather can quickly dry and chap your skin, so any time you'll be outdoors, especially for extended periods of time, be sure to cover up exposed areas. Keep an extra set of gloves and a scarf in your vehicle so you're prepared for unexpected time outdoors, whether from an accident or impromptu stop at a local park for some fresh air and exercise.
Wear sunscreen. Winter sun rays are just as strong as summer rays, even if you don't feel their heat quite as much. In fact, snow burns that result from sun reflecting off the snow can be even more dangerous than regular sunburns. Protect your skin from burning and drying out by using sunscreen with an SPF of at least 15 any time you venture outdoors.
