Denver Sunscreen Secrets: High Altitude Burns, Hidden Toxins.
By Franklin Everett ShawDenver, the Mile High City, boasts stunning mountain views and a vibrant outdoor culture. But lurking beneath the clear blue skies is a silent threat: intense ultraviolet (UV) radiation. Choosing the right sunscreen isn’t just a summer afterthought here; it’s a crucial daily defense against sun damage, and frankly, a potential lifesaver.
Forget the generic advice about “broad spectrum” and “reapplying every two hours.” We’re diving deep into the specifics of sunscreen in Denver, focusing on mineral-based options and why they’re often the superior choice, especially for those with sensitive skin or conditions like lupus.
Denver’s altitude significantly increases UV exposure. For every 1,000 feet above sea level, UV radiation increases by approximately 4-5%. At 5,280 feet, Denverites are exposed to roughly 20-25% more UV radiation than someone at sea level.
This means that the SPF (Sun Protection Factor) you might use effectively in, say, Miami, simply won’t cut it in Denver.
So, what SPF should you be reaching for?
The American Academy of Dermatology recommends SPF 30 or higher. In Denver, I’d argue that SPF 50 is the minimum you should consider, especially during peak sunlight hours (10 AM to 4 PM).
But SPF is just one piece of the puzzle. The type of sunscreen matters just as much, if not more.
Chemical sunscreens, which absorb UV radiation, contain ingredients like oxybenzone, avobenzone, octinoxate, and octisalate. These chemicals have been linked to hormone disruption and allergic reactions in some individuals.
Mineral sunscreens, on the other hand, use zinc oxide and/or titanium dioxide to physically block UV rays. These minerals are generally considered safer and gentler on the skin.
For individuals with sensitive skin, eczema, rosacea, or conditions like lupus, mineral sunscreens are often the preferred choice. Lupus, in particular, is often exacerbated by sun exposure, making effective and gentle sun protection paramount.
Why mineral over chemical in Denver?
First, the increased UV intensity demands a robust defense. Mineral sunscreens provide a physical barrier that’s less likely to break down under intense sunlight compared to some chemical formulations.
Second, the dry climate of Denver can further irritate sensitive skin. Chemical sunscreens can sometimes exacerbate this dryness, while mineral sunscreens tend to be more moisturizing.
Third, consider the potential for absorption. Chemical sunscreens are absorbed into the skin, which is how they work. Mineral sunscreens sit on top of the skin, creating a physical shield. This reduces the risk of systemic absorption of potentially harmful chemicals.
Choosing the right mineral sunscreen can be tricky. Look for products that contain at least 20% zinc oxide for optimal protection.
Avoid sunscreens with added fragrances, dyes, or preservatives, as these can irritate sensitive skin.
Read the ingredient list carefully. Even some “mineral” sunscreens contain small amounts of chemical filters.
Application is key. Don’t skimp!
Most people apply far too little sunscreen. You should use about one ounce (a shot glass full) to cover your entire body.
Apply sunscreen 15-30 minutes before sun exposure to allow it to bind to your skin.
Reapply every two hours, or more frequently if you’re swimming or sweating.
Don’t forget often-overlooked areas like your ears, the back of your neck, and the tops of your feet.
Consider using a sunscreen stick for easy application to the face and around the eyes.
Common mistakes?
- Relying solely on makeup with SPF. Makeup SPF is often too low and not applied thickly enough to provide adequate protection.
- Not reapplying frequently enough.
- Missing spots during application.
- Using expired sunscreen. Sunscreen degrades over time, so check the expiration date.
- Thinking that cloudy days mean you don’t need sunscreen. UV radiation can penetrate clouds.
Where to find good mineral sunscreens in Denver?
- Natural Grocers: This chain specializes in organic and natural products, including a wide selection of mineral sunscreens.
- Whole Foods Market: Another reliable source for mineral sunscreens, with knowledgeable staff who can help you choose the right product.
- Local pharmacies: Many local pharmacies, like Capitol Heights Pharmacy, are starting to stock more mineral sunscreen options. Ask your pharmacist for recommendations.
- REI: If you’re heading to the mountains for hiking or skiing, REI offers a variety of high-performance mineral sunscreens designed for outdoor activities.
Consider these specific scenarios:
- Skiing in Breckenridge: The altitude and reflective snow create extreme UV conditions. Use a high-SPF mineral sunscreen, lip balm with SPF, and wear sunglasses.
- Hiking in Red Rocks Amphitheatre: Apply sunscreen liberally before your hike and reapply frequently, especially if you’re sweating. Wear a wide-brimmed hat for added protection.
- Walking around downtown Denver: Even a short walk can expose you to significant UV radiation. Apply sunscreen to your face, neck, and hands every morning.
For individuals with lupus, consult with your dermatologist about the best sunscreen options for your specific needs. They may recommend specific brands or formulations.
Remember, sunscreen is just one part of sun protection. Wear protective clothing, seek shade during peak sunlight hours, and wear sunglasses to protect your eyes.
Living in Denver means embracing the outdoors, but it also means taking sun protection seriously. By choosing a mineral sunscreen, applying it correctly, and taking other sun-safe precautions, you can enjoy the Mile High City without compromising your health. Don’t treat it as an option, treat it as a necessity.
