Denver Sunscreen: Altitude Lies Burning Lasers Fast?
By Franklin Everett ShawThe sun feels different in Denver. It’s not just the dry air; it’s a palpable intensity that seems to burn right through you. Many newcomers dismiss it, attributing any redness to a day of hiking or skiing. But that dismissal is a dangerous game, especially in a city where the sun’s rays pack a much stronger punch.
Denver’s high altitude is the culprit. The thinner atmosphere filters less UV radiation, meaning you’re exposed to significantly more harmful rays than at sea level. This increased exposure, coupled with the city’s often cloudless skies, creates a perfect storm for sun damage.
So, how do you navigate this sun-drenched reality and protect your skin effectively? It starts with understanding the science and making informed choices about sunscreen.
First, let’s talk SPF. SPF, or Sun Protection Factor, measures a sunscreen’s ability to filter UVB rays, the primary cause of sunburn. The American Academy of Dermatology recommends using a sunscreen with an SPF of 30 or higher. But in Denver, SPF 30 is the minimum, not the ideal.
Why? Because even SPF 30 only blocks about 97% of UVB rays. That remaining 3% can still cause significant damage, especially when amplified by Denver’s altitude. Consider bumping up to SPF 50, which blocks about 98% of UVB rays. That extra 1% makes a difference over time.
You can find plenty of SPF 30+ sunscreens at local retailers like King Soopers and Walgreens. But don’t just grab the first bottle you see. Pay attention to the ingredients.
There are two main types of sunscreen: mineral and chemical. Mineral sunscreens, containing zinc oxide and/or titanium dioxide, physically block UV rays. They’re generally considered safer for sensitive skin and the environment. Chemical sunscreens, on the other hand, absorb UV rays and convert them into heat.
In Denver, mineral sunscreens are often the better choice. The intense sun can sometimes cause chemical sunscreens to break down faster, reducing their effectiveness. Look for brands like EltaMD, Blue Lizard, or Thinksport, which are readily available and known for their quality mineral formulations.
But even the best sunscreen is useless if you don’t apply it correctly. This is where most people fail.
The biggest mistake? Not using enough. You need about one ounce – a shot glass full – to cover your entire body. Don’t skimp! Apply liberally and evenly.
Another common error is forgetting to reapply. Sunscreen needs to be reapplied every two hours, or more frequently if you’re swimming or sweating. Set a timer on your phone to remind you.
And don’t forget the often-neglected areas: ears, neck, tops of your feet, and even your scalp (especially if you have thinning hair). These areas are particularly vulnerable to sun damage.
Cloudy days are no excuse to skip sunscreen. UV rays can penetrate clouds, so you’re still at risk of sunburn and skin damage. In fact, on cloudy days, UV radiation can be more intense due to reflection off the clouds.
Winter sports in Colorado amplify the risk. Snow reflects up to 80% of UV radiation, effectively doubling your exposure. If you’re skiing, snowboarding, or even just walking around downtown Aspen, sunscreen is non-negotiable.
Consider using a lip balm with SPF as well. Your lips are particularly susceptible to sun damage.
Now, let’s address the elephant in the room: skin cancer. Denver’s high altitude and intense sun contribute to a higher risk of skin cancer. Regular sunscreen use is crucial for prevention.
But sunscreen is just one piece of the puzzle. Regular skin checks are also essential. Examine your skin monthly for any new or changing moles or spots. If you notice anything suspicious, see a dermatologist immediately.
Early detection is key to successful skin cancer treatment. Don’t delay.
One challenge specific to Denver is the dry air. Sunscreen can sometimes feel heavy or greasy on dry skin. Look for lightweight, hydrating formulas that won’t clog pores.
Another pitfall is relying solely on sunscreen. While sunscreen is essential, it’s not a foolproof shield. Wear protective clothing, such as long sleeves, hats, and sunglasses, whenever possible. Seek shade during peak sun hours (10 am to 4 pm).
Remember, sun protection is a year-round commitment in Denver. The sun doesn’t take a break, and neither should you. Make sunscreen a daily habit, just like brushing your teeth.
Don’t fall victim to the misconception that a little sun is good for you. While vitamin D is important, you can get it safely through diet or supplements. There’s no such thing as a “healthy tan.” A tan is a sign that your skin has been damaged by UV radiation.
Protecting your skin in Denver requires vigilance and knowledge. By understanding the risks, choosing the right sunscreen, and applying it correctly, you can enjoy the city’s sunshine without compromising your health.
So, next time you’re at King Soopers or Walgreens, take a few extra minutes to choose your sunscreen wisely. Your skin will thank you for it. And remember, prevention is always better than cure.
