Want to know more about risks of the winter?

Cancer and aging

Even in the winter and on cloudy days, it’s important to guard your skin against cancer and aging.

Harmful ultraviolet (UV) rays are present year-around. They can even filter through dark cloud coverage to reach your skin.

Some studies even show an effect called cloud enhancement of UV radiation. The sun’s beams reflect off the sides of clouds causing radiation to be more focused and dangerous.

The primary cause of skin cancer is too much sun exposure.

5,4 million basal and squamous cell skin cancer are diagnosed each year.


The good news: It’s one of the easiest to prevent, including the most serious form, malignant melanoma. Other more common types of skin cancer, such as basal cell and squamous cell carcinomas, are treatable if found early.

Wear sunscreen year-around to lower your chances of getting skin cancer,”.

Winter protection

During winter, the Earth’s Northern Hemisphere points away from the sun, and the atmosphere blocks some of the sun’s harmful UV rays. Temperatures drop as the sun’s rays are further away.

But harmful ultraviolet (UV) rays are present year-around. And snow reflects up to 80% of the sun’s rays

Higher altitude means higher risk

The risk for sunburn is higher because the thinner atmosphere doesn’t block as many of the sun’s harmful rays.

Just one blistering sunburn increases your skin cancer risk and should be reported to your doctor. Five or more sunburns doubles your risk for melanoma.

Sunscreen protection

Wear sunscreen that’s at least SPF 30, broad spectrum to block both UVA and UVB rays, and water resistant.

Apply sunscreen liberally to dry skin 30 minutes before going outdoors.

Pay extra attention to face, ears, hands and arms.

Reapply sunscreen every two hours or immediately after swimming or sweating.

“Applying sunscreen regularly decreases the number of sunburns you get,”
