As summer is coming to an end and winter is upon us, sunscreen use is just as important. Our exposure to the sun during winter months can increase significantly for most Coloradans and put us at an even higher risk for skin cancer, especially skiers and snowboarders. Colorado is known for its endless outdoor activities, higher elevation and being one of the sunniest states in the country.
When your skin is exposed to sun without protection, it is being introduced to two different ultraviolet (UV) rays, UVA and UVB. This is damaging to your superficial and the deep layers of your skin. Congruently leading to skin cancer, wrinkles, and dark spots. Due to the pure intensity of the sun at a higher altitude, especially the reflection off the snow, it can significantly increase your risk for skin cancer.
According to a research study completed at the Department of Dermatology at the New York University School of Medicine, it showed for every 1,000 feet you gain in elevation above sea level, the intensity of the sunrays increases up to 10%. Therefore, the higher the altitude, the quicker the person can develop a sunburn.
For example, the average complexion individual without skin protection in Vail would burn after only six minutes of sun exposure on a clear day. Research at Australasian College of Dermatologist has shown that the time spent around areas where sun reflects off snow and ice is 200% more harmful UV exposure than being at the beach.
Because of the increase in UV exposure in Colorado, especially at higher altitudes, we recommend finding a sunscreen that is at least 30 SPF or higher, water-soluble, and contains zinc oxide.
Other ways to protect your skin are to wear a wide-brim hat, SPF lip balm, along with clothing that contains UV protection. It is important to reapply sunscreen at least every two hours since increased UV rays, sweat, wind, and snow can decrease its effectiveness.
In addition, winter months can bring on dry skin which unfortunately is very common. The most common cause is due to low humidity in Colorado which in return causes your skin to lose water. Dry skin leads to additional symptoms such as itching, flaking, cracking and discomfort. Avoiding hot showers, baths and hot tubs is a suggested best practice. Focus on using mild cleansers and applying moisturizing creams or ointments that contain ingredients such as ceramides, glycerin, hyaluronic acid, and urea. It is important to apply these emollients at suggested intervals throughout the day.
Before you consider leaving your house whether it is sunny, overcast, rainy, warm, or cold day, be sure to add sunscreen to your daily routine. This will decrease your sun damage and in return decrease your risk for skin cancer. Melanoma, the worst skin cancer, is the fifth most diagnosed skin cancer for men in Colorado and the sixth for women.
We encourage individuals to get yearly skin exams to help detect, prevent, and treat skin cancer.
