Aspen's Secret Killer: Sunscreen Isn't Enough
By Franklin Everett ShawAre you slathering on sunscreen and thinking you’re invincible against the Colorado sun? Think again. Denver’s mile-high altitude, combined with the state’s notoriously dry air, creates a UV radiation gauntlet that most people, even seasoned outdoor enthusiasts, underestimate. Mineral sunscreens, while a good starting point, often fall short in providing adequate protection in the Rockies.
Let’s be blunt: relying solely on mineral sunscreen in Denver is a recipe for sunburn, premature aging, and increased skin cancer risk.
The problem isn’t necessarily the sunscreen itself, but how it’s used and the environmental factors at play. Mineral sunscreens, containing zinc oxide and titanium dioxide, work by creating a physical barrier that reflects UV rays. This is generally safer than chemical sunscreens, which absorb UV radiation. However, at higher altitudes, the atmosphere is thinner, meaning less UV radiation is absorbed before it reaches your skin.
Denver receives significantly more intense UV radiation than cities at sea level.
Furthermore, the dry Colorado air can dehydrate your skin, compromising its natural protective barrier. This makes you even more vulnerable to sun damage. Mineral sunscreens can also dry out the skin, exacerbating the problem.
So, what’s a sun-conscious Denverite to do?
First, understand that SPF is not a linear scale. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The difference may seem small, but in intense UV environments, that extra 1% can be crucial. Don’t skimp on the SPF.
Second, application is key. Most people don’t apply enough sunscreen. You need about one ounce (a shot glass full) to cover your entire body. Reapply every two hours, or immediately after swimming or sweating. Don’t forget often-missed areas like your ears, the back of your neck, and the tops of your feet.
Third, mineral sunscreens can leave a white cast, especially on darker skin tones. This often leads people to apply less sunscreen than they need. Look for tinted mineral sunscreens or those with micronized zinc oxide and titanium dioxide, which are less likely to leave a visible residue.
But sunscreen alone isn’t enough. You need a multi-pronged approach.
Let’s talk about clothing. Not all clothing is created equal when it comes to sun protection. Look for clothing with an Ultraviolet Protection Factor (UPF) rating. UPF measures how much UV radiation can penetrate the fabric. A UPF of 50 means that only 1/50th of the sun’s UV radiation can pass through the fabric.
Several brands offer excellent UPF clothing options. For example, Coolibar and Patagonia (with a store in Boulder) both have a wide range of UPF-rated shirts, pants, and hats. Look for tightly woven fabrics and darker colors, as they tend to offer better protection.
Consider a wide-brimmed hat. A baseball cap only protects your forehead and nose. A wide-brimmed hat will shield your face, ears, and neck.
Sunglasses are also essential. Choose sunglasses that block 100% of UVA and UVB rays. Wrap-around styles offer the best protection.
Timing is also crucial. The sun’s rays are strongest between 10 a.m. and 4 p.m. Try to avoid prolonged sun exposure during these peak hours. If you must be outside, seek shade whenever possible.
Now, let’s delve into the often-overlooked aspect of sun protection: nutrition.
What you eat can significantly impact your skin’s ability to withstand sun damage. A diet rich in antioxidants can help neutralize free radicals produced by UV radiation.
Focus on foods high in vitamins C and E, beta-carotene, and selenium. Good sources include berries, leafy greens, nuts, seeds, and fatty fish.
Specifically, consider incorporating these into your Denver diet:
- Colorado Peaches: Rich in Vitamin C and antioxidants.
- Kale: Abundant in vitamins A, C, and K, as well as antioxidants.
- Wild-Caught Salmon: Provides omega-3 fatty acids and selenium, which can help protect against sun damage.
Hydration is also critical. The dry Colorado air can quickly dehydrate you, making your skin more vulnerable to sun damage. Drink plenty of water throughout the day. Consider adding electrolytes to your water, especially if you’re active.
Don’t wait until you’re thirsty to drink. Carry a water bottle with you and sip on it regularly.
A common mistake is thinking that you’re protected on cloudy days. Clouds don’t block UV radiation. In fact, they can even amplify it by reflecting the rays. You still need to wear sunscreen and take other precautions on cloudy days.
Another pitfall is relying on sunscreen alone. As we’ve established, sunscreen is just one piece of the puzzle. You need a comprehensive approach that includes clothing, timing, and nutrition.
Finally, don’t forget about your lips. Lips are particularly vulnerable to sun damage. Use a lip balm with an SPF of at least 30.
Protecting yourself from the intense Colorado sun requires a proactive and multi-faceted approach. Don’t rely solely on mineral sunscreen. Supplement it with UPF clothing, strategic timing, and a diet rich in antioxidants and hydration. By taking these steps, you can enjoy the beauty of Colorado without sacrificing your skin’s health. Remember, prevention is always better than cure.
