From deep-powder ski days to sun-kissed snowshoe treks, our snowy winter wonderland may be sparkling on the outside—but on the inside, it’s sucking the life out of us. Cold temperatures, low humidity, and harsh wind all rob the skin of moisture. Give it a break: It’s only half a millimeter at its thinnest point, yet it protects us from damage and infection. Let’s spare a moment for the body’s largest organ—the skin.
Cover Thyself
The sun may be farther away in wintertime, but it’s out there. As we go higher, there is less atmosphere to filter the its UV rays, creating greater risk of serious sunburn. At an altitude of 5,000 feet—where most ski resorts are—there is 20 percent more UV radiation than at sea level. Snow also reflects 85 percent of the sun’s harmful UV rays, bouncing back off the ground and burning skiers and snowboarders under the chin and nose.
Time to cover up. Hats, neck gaiters, balaclavas, wraparound glasses, and goggles are the best way of blocking out the sun. Use a broad-spectrum sunscreen of at least SPF 30 that blocks both UVA and UVB. Look for at least 4–5 percent zinc oxide (also called micronized zinc), or titanium dioxide, or Parsol 1789 (also called avobenzone) among the list of active ingredients. Wear complete sunblock on sun-sensitive areas like nose, ears, and lips. Apply before you go outside, and remember, sunscreens have a shelf life: Check the date on the package.
Keep Moist
Indoors, you may be shielded from the sun, but artificially heated winter air is still a killer. If you thought moisturizers keep you hydrated, think again. All they really do is lock in the skin’s own moisture to prevent dryness and cracking. The more oil a moisturizer contains, the more effectively it protects against moisture loss. Moisturizers that come in ointment form contain the most oil, forming a thick protective layer on the skin.
Use a Humidifier
Closed windows and indoor heating draw the moisture out of the air. Humidifiers do a good job of putting it back, keeping skin and nasal passages from drying out. In hotels, fill the bath with hot water and leave overnight.
Pucker Up
The skin on the lips is more delicate, so it retains less moisture and tends to dry out more quickly than other areas. Licking your lips only dries them out and contributes to chapping. Use lip balm with waxes or lanolin to seal in moisture. It should also contain SPF.
Go Bare
Metal jewelry in severe temperatures is a no-no. Leave your pierced earrings at home. Cold metal posts will make you feel colder than you need to.
Drink Water
Exercise, dry air, and alcohol all sap the body of water reserves that are essential for healthy functioning. Altitudes greater than 8,000 feet may trigger increased urination and more rapid breathing, which also use up more of your fluid reserves. Combine just a few of those factors—think soaking in the hot tub with a few beers after skiing—and voilà, a recipe for dehydration. Around 2 liters of water a day is recommended, but if you’re working hard on the trails, you’ll need much more. Solution: Strap on a low-profile hydration pack, like The North Face Dogfish with a 70-ounce water reservoir.
