Denver Lasers: Altitude Hiding Sunburn Risk?
By Franklin Everett ShawThe sun feels different in Denver. It’s not just a feeling; it’s a reality. Living at a mile above sea level, or visiting for a ski trip, means you’re closer to the sun and its harmful ultraviolet (UV) rays. This isn’t just about avoiding a sunburn on your vacation; it’s about long-term skin health and preventing serious conditions.
Denver’s altitude presents a unique challenge. The atmosphere filters less UV radiation, increasing exposure by approximately 4-5% for every 1,000 feet of elevation. This means Denverites are exposed to roughly 20-25% more UV radiation than someone at sea level.
Sunscreen is your first line of defense, but not all sunscreens are created equal. Forget SPF 30; in Denver, SPF 50 or higher is non-negotiable. Look for broad-spectrum protection, meaning it shields against both UVA and UVB rays. Chemical sunscreens absorb UV radiation, while mineral sunscreens (containing zinc oxide or titanium dioxide) create a physical barrier. Mineral sunscreens are generally considered safer for sensitive skin and the environment.
Applying sunscreen correctly is crucial. Most people don’t use enough. Aim for about one ounce – enough to fill a shot glass – to cover your entire body. Don’t forget often-missed areas like your ears, the back of your neck, and the tops of your feet. Reapplication is key, especially when engaging in outdoor activities. Reapply every two hours, or immediately after swimming or sweating.
Consider this scenario: you’re hiking in Red Rocks Amphitheatre. The sun is beating down, and you’re sweating. You applied sunscreen before you left, but it’s been three hours. You’re now significantly increasing your risk of sunburn and long-term skin damage. Carry a travel-sized sunscreen and reapply at the trailhead.
Beyond sunscreen, protective clothing is essential. Look for clothing with an Ultraviolet Protection Factor (UPF) rating. UPF indicates how much UV radiation the fabric blocks. A UPF of 50 means the fabric blocks 98% of UV rays. Many outdoor retailers in Denver, like REI and Wilderness Exchange, carry a wide selection of UPF-rated clothing, from long-sleeved shirts and pants to hats and gloves.
Sunglasses are another critical piece of protective gear. The sun’s rays can damage your eyes, leading to cataracts and other vision problems. Choose sunglasses that block 100% of UVA and UVB rays. Wrap-around styles offer the best protection, as they prevent sunlight from entering from the sides. Look for sunglasses with an ANSI Z80.3 rating, which indicates they meet the American National Standards Institute’s requirements for UV protection.
Let’s say you’re skiing at Breckenridge. The sun is reflecting off the snow, intensifying UV exposure. You’re wearing sunglasses, but they don’t fit properly, leaving gaps around your eyes. This can lead to snow blindness, a painful condition caused by UV damage to the cornea. Invest in a good pair of ski goggles that fit snugly and offer 100% UV protection.
Even on cloudy days, UV radiation can penetrate the clouds. Don’t be fooled into thinking you don’t need protection. Up to 80% of the sun’s UV rays can pass through clouds. Make sunscreen and protective clothing a daily habit, regardless of the weather.
Recognizing sunburn is crucial, especially at high altitude where it can develop quickly. Symptoms include red, painful skin, blistering, and swelling. If you suspect you have a sunburn, get out of the sun immediately. Cool the affected area with a cold compress or a cool shower. Apply a moisturizer containing aloe vera to soothe the skin. Drink plenty of fluids to stay hydrated.
For severe sunburns, seek medical attention. Symptoms like fever, chills, nausea, and dizziness may indicate heatstroke or dehydration. A doctor can prescribe stronger pain relievers and topical creams to help with healing.
A common mistake is thinking that a base tan protects you from sunburn. A tan is a sign that your skin has already been damaged by UV radiation. It provides minimal protection, equivalent to an SPF of only 2-4. Don’t rely on a tan to shield you from the sun’s harmful rays.
Another pitfall is neglecting children’s skin. Children are more susceptible to sunburn and long-term skin damage because their skin is thinner and more delicate. Protect children with sunscreen, protective clothing, and hats. Teach them about sun safety from a young age.
Consider this: you’re visiting Denver with your family. You’re excited to explore the Denver Zoo, but you forget to apply sunscreen to your children. By the end of the day, they’re red and uncomfortable. This could have been easily avoided with a little planning and preparation.
Denver’s unique environment demands a proactive approach to sun protection. By understanding the increased UV exposure at high altitude, choosing the right sunscreen and protective gear, and practicing sun-safe habits, you can enjoy the city’s outdoor activities without compromising your skin health. Don’t let the beautiful Colorado sunshine become a source of long-term damage. Be smart, be prepared, and protect your skin.
