Why You Should Wear Your Sunscreen this Winter

Many of us associate sunscreen with the long days of summer. But, according to the Skin Cancer Foundation, there’s good reason to think sunscreen especially when there’s snow in the forecast.

As it turns out, the sun emits UVB rays (which cause sunburn) and UVA rays (responsible for skin cancer) all year long. Plus, snow is highly reflective of UV radiation with fresh snow reflecting even more UV radiation than water. Add to that the fact that UV radiation increases by 5% with every thousand feet you rise above sea level. The higher the peaks you ski, board, or climb, the greater your exposure.

If you plan to spend time outdoors this winter, use these tips to protect yourself from damaging rays:

Wear protective clothing:

- Beanies, balaclavas, and earmuffs will keep you warm and protect your head and ears from UV exposure.

- For added protection, look for clothing with built-in ultraviolet protection (marketed as UPF).

Wear sunscreen:

- Always apply sunscreen at least 20 minutes before heading outside (Yes, even on cloudy days).

- Use a broad-spectrum, water-resistant product that’s at least SPF 30.

- Use a broad-spectrum, water-resistant SPF 30 (or higher) lip balm or zinc cream to protect your lips.

- Because snow and strong winds can wear away sunscreen and reduce its effectiveness, be sure to keep a small bottle with you in your pocket and reapply every two hours.

 A bonus of wearing sunscreen is that it helps prevent windburn.

And, because UV rays can increase your risk for cataracts, eye cancer, and photokeratitis, be sure to wear UV-protective goggles or sunglasses to prevent damage and snow blindness. Be sure to select sunglasses that provide 100% UV or UV400 protection, or block both UV-A and UV-B rays.  

If you do end up with a winter sunburn, take the same precautions you would in the summer to treat it and prevent further skin damage. This includes:

Stay indoors to avoid further exposure, or, if you must be outdoors, staying in the shade as much as possible.

Cool damaged skin using cold compresses or by taking a cool (not hot) bath.

Drink plenty of water to stay hydrated, as sunburn can dehydrate your body.

Apply moisturizers or aloe vera gel to provide relief and promote healing.
