Denver SPF: Altitude Sun Lies Burning Lips?
By Franklin Everett ShawDon’t let the sunshine fool you; Denver’s altitude demands serious sun protection. Many underestimate the intensity of the sun at higher elevations, leading to painful sunburns and long-term skin damage. This isn’t just about vanity; it’s about health.
Denver, sitting at 5,280 feet (a mile high!), experiences significantly higher levels of UV radiation than lower-altitude locations. The thinner atmosphere filters less of the sun’s harmful rays. This means you’re exposed to more UV radiation, and you burn faster.
So, what SPF should you really be using in Denver? Forget the SPF 15 you might get away with at sea level.
The general recommendation is SPF 30 or higher. However, in Denver, I’d argue that SPF 50 is the minimum you should consider for daily use, especially during peak sunlight hours (10 AM to 4 PM).
Why SPF 50? It blocks approximately 98% of UVB rays, compared to SPF 30’s 97%. That 1% difference might seem small, but it adds up over time, especially when you’re exposed to intense UV radiation.
Think of it this way: imagine you’re hiking in Red Rocks Amphitheatre. The sun is beating down, reflecting off the red rocks. You’re sweating, and your sunscreen is likely wearing off. That extra protection from SPF 50 can make a significant difference in preventing a burn.
But SPF isn’t the only factor. You need to consider the type of sunscreen.
Broad-spectrum protection is crucial. This means the sunscreen protects against both UVA and UVB rays. UVA rays contribute to aging and skin cancer, while UVB rays are the primary cause of sunburn.
Look for sunscreens containing ingredients like zinc oxide, titanium dioxide, avobenzone, or ecamsule. These provide broad-spectrum protection. Mineral sunscreens (zinc oxide and titanium dioxide) are generally considered safer and more effective, especially for sensitive skin.
Now, let’s talk about application. Most people don’t apply enough sunscreen.
You should be using about one ounce (a shot glass full) to cover your entire body. Reapply every two hours, or more frequently if you’re sweating or swimming. Don’t forget often-missed areas like your ears, the back of your neck, and the tops of your feet.
A common mistake is applying sunscreen only when you’re actively in the sun. UV radiation is present even on cloudy days. Make sunscreen application a part of your daily routine, just like brushing your teeth.
What about specific product recommendations? You can find great options at local Denver pharmacies like Walgreens and CVS, as well as outdoor retailers like REI and Sports Authority (if you can still find one!).
For daily use, I recommend EltaMD UV Clear Broad-Spectrum SPF 46. It’s lightweight, oil-free, and contains niacinamide, which can help with redness and inflammation. It’s readily available at many dermatologists’ offices and some pharmacies in Denver.
For outdoor activities like hiking or skiing, consider a water-resistant and sweat-resistant sunscreen like Neutrogena Ultra Sheer Dry-Touch Sunscreen SPF 55. It’s affordable and widely available. Just remember to reapply frequently.
Don’t forget your lips! Lip balm with SPF is essential, especially in Denver’s dry climate.
Look for lip balms with an SPF of 30 or higher. Reapply frequently, especially after eating or drinking. A good option is Aquaphor Lip Repair with SPF 30.
Skiing in Colorado presents unique challenges. The altitude is even higher, and the snow reflects sunlight, increasing your exposure.
Use a high SPF sunscreen (50 or higher) and reapply frequently. Consider using a physical sunscreen (zinc oxide or titanium dioxide) as it provides a more robust barrier against the sun. Don’t forget to protect your lips and wear sunglasses or goggles to protect your eyes.
Hiking in the summer also requires extra precautions. The sun is intense, and you’re likely to be sweating.
Wear a hat and sunglasses, and seek shade whenever possible. Reapply sunscreen every two hours, or more frequently if you’re sweating. Consider wearing sun-protective clothing with a UPF (Ultraviolet Protection Factor) rating.
One often-overlooked aspect is the expiration date of your sunscreen. Sunscreen ingredients degrade over time, making them less effective. Check the expiration date on your sunscreen and discard it if it’s expired.
Storing your sunscreen properly is also important. Heat can degrade sunscreen ingredients. Store your sunscreen in a cool, dry place, away from direct sunlight. Don’t leave it in your car on a hot day.
Choosing the right SPF in Denver isn’t just about picking a number. It’s about understanding the unique challenges of high-altitude sun exposure and taking the necessary precautions to protect your skin. It’s about making informed choices and adopting a proactive approach to sun safety.
Remember, prevention is key. Sunburns are painful and increase your risk of skin cancer. Protect yourself and your loved ones by using sunscreen properly and consistently. Enjoy the beautiful Colorado sunshine, but do it safely.
