**Denver Trackers: Altitude Lies Burning Summer Skin?**

Have you ever felt like you’re aging faster than your friends who live at sea level? Or maybe you’ve noticed your skin getting drier and more irritated, even with your usual skincare routine? If you’re a Denver resident, you’re not imagining things. The Mile High City’s altitude presents unique challenges to our skin and overall health, especially during the summer months. Let’s dive into how to protect yourself.

Denver’s high altitude means increased exposure to ultraviolet (UV) radiation. The atmosphere is thinner, filtering less of the sun’s harmful rays. This is compounded by the fact that snow, common even in early summer in the mountains west of Denver, reflects up to 80% of UV radiation, effectively doubling your exposure.

So, what can you do? Sunscreen is your first line of defense, but not all sunscreens are created equal. For Denver’s intense sun, you need a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum means it protects against both UVA and UVB rays.

• UVB rays are primarily responsible for sunburn.
• UVA rays penetrate deeper into the skin, contributing to premature aging and skin cancer.

Look for sunscreens containing zinc oxide or titanium dioxide. These are mineral sunscreens that create a physical barrier against the sun, and are generally considered safer for sensitive skin. Chemical sunscreens absorb UV rays, and while effective, can sometimes cause irritation.

A common mistake is not applying enough sunscreen. You should use about one ounce (a shot glass full) to cover your entire body. Don’t forget often-missed spots like your ears, the back of your neck, and the tops of your feet, especially if you’re wearing sandals while strolling along South Pearl Street. Reapply every two hours, or immediately after swimming or sweating. If you’re hiking near Red Rocks Amphitheatre, reapplication is crucial, even on cloudy days.

Consider a sunscreen specifically formulated for sports or outdoor activities. These are often water-resistant and sweat-resistant, providing longer-lasting protection. Brands like EltaMD and La Roche-Posay offer excellent options. Don’t skimp on the lip balm either. Choose one with an SPF of 30 or higher to protect your lips from sun damage.

Beyond sunscreen, protective clothing is essential. Wear wide-brimmed hats to shield your face and neck. Sunglasses are also a must to protect your eyes from UV radiation, which can lead to cataracts and macular degeneration. Look for sunglasses that block 99-100% of UVA and UVB rays.

The dry air in Denver is another significant challenge. The low humidity can quickly dehydrate your skin, leading to dryness, itching, and even eczema flare-ups. Combat this by drinking plenty of water throughout the day. A good rule of thumb is to drink half your body weight in ounces of water daily.

Carry a reusable water bottle with you and sip on it regularly. Avoid sugary drinks and excessive caffeine, as these can actually dehydrate you. Consider investing in a humidifier for your home, especially for your bedroom. This will add moisture to the air, helping to keep your skin hydrated while you sleep.

Moisturizing is also crucial. Choose a rich, emollient moisturizer that contains ingredients like hyaluronic acid, ceramides, and shea butter. Hyaluronic acid attracts and retains moisture, while ceramides help to repair the skin’s barrier function. Apply moisturizer immediately after showering or bathing to lock in moisture.

Avoid hot showers and baths, as these can strip your skin of its natural oils. Use lukewarm water and a gentle, fragrance-free cleanser. Consider using a hydrating face mask once or twice a week to give your skin an extra boost of moisture.

Altitude sickness can also manifest as skin issues. The lower oxygen levels at high altitude can lead to increased inflammation and oxidative stress, which can exacerbate existing skin conditions like acne and rosacea. If you’re visiting Denver from a lower altitude, give your body time to adjust before engaging in strenuous activities.

If you experience symptoms of altitude sickness, such as headache, nausea, or fatigue, seek medical attention. Certain medications can help to alleviate these symptoms.

Pay attention to any changes in your skin. If you notice any new moles, changes in existing moles, or persistent sores that don’t heal, see a dermatologist immediately. Early detection is key to treating skin cancer effectively.

Denver’s unique environment demands a proactive approach to skincare. By understanding the challenges of high altitude and implementing these strategies, you can protect your skin and enjoy all that the Mile High City has to offer. Remember, consistency is key. Make sunscreen application, hydration, and moisturizing a part of your daily routine, and your skin will thank you.
