Why Seattle Runners Should Fear Utah Sunscreen

Ever felt like your skin was sizzling even on a cloudy day? That’s the Utah sun, and it’s a whole different beast than what Seattle runners are used to. Seattle’s gentle drizzle and perpetual overcast create a false sense of security.

Utah’s high altitude and dry air amplify the sun’s intensity, making sunscreen a non-negotiable part of your running gear. This isn’t just about avoiding a sunburn; it’s about long-term skin health and preventing premature aging.

Seattle runners, lulled by the Pacific Northwest’s milder UV index, often underestimate the power of the Utah sun. They might skip sunscreen altogether, apply it sparingly, or use a low SPF, thinking it’s enough.

This is a recipe for disaster in Utah.

The UV index in Salt Lake City, for example, can easily reach 8 or higher on a sunny summer day, even with some cloud cover. Seattle, on the other hand, rarely sees UV indexes that high.

So, what’s a Seattle runner to do when hitting the trails in Utah?

First, understand the difference between SPF numbers. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%.

While the difference seems small, that extra 1% can be significant in Utah’s intense sun.

I recommend a broad-spectrum sunscreen with an SPF of at least 50 for Utah runs.

Broad-spectrum means it protects against both UVA and UVB rays.

Don’t skimp on application. Most people only apply 25-50% of the recommended amount of sunscreen.

You need about one ounce (a shot glass full) to cover your entire body.

Pay special attention to exposed areas like your face, neck, ears, arms, and legs.

Reapply sunscreen every two hours, or more often if you’re sweating heavily.

This is crucial, especially during long runs.

Many Seattle runners make the mistake of applying sunscreen only once before their run.

This is not sufficient in Utah’s sun.

Consider using a sweat-resistant and water-resistant sunscreen.

These sunscreens are designed to stay on your skin even when you’re sweating.

Look for sunscreens that contain zinc oxide or titanium dioxide.

These are mineral sunscreens that are generally considered to be safer for your skin and the environment.

Avoid sunscreens that contain oxybenzone and octinoxate.

These chemicals can be harmful to coral reefs and may also have negative effects on human health.

Another common mistake is forgetting to protect your lips.

Use a lip balm with an SPF of at least 30.

The skin on your lips is very thin and susceptible to sun damage.

Wear sunglasses to protect your eyes from the sun’s harmful rays.

Choose sunglasses that block 100% of UVA and UVB rays.

A wide-brimmed hat can also provide extra protection for your face and neck.

Consider running during the early morning or late afternoon hours when the sun is less intense.

This can help reduce your exposure to UV radiation.

Even on cloudy days, UV rays can penetrate through the clouds.

Don’t be fooled by overcast skies.

Always wear sunscreen, even when it’s cloudy.

Here’s a step-by-step application strategy tailored for Utah’s unique conditions:

1. Apply sunscreen 15-30 minutes before heading out for your run. This allows the sunscreen to absorb into your skin.
2. Apply a generous amount of sunscreen to all exposed areas of your skin.
3. Don’t forget your ears, neck, and the back of your hands.
4. Reapply sunscreen every two hours, or more often if you’re sweating heavily.
5. Use a lip balm with SPF 30 or higher.
6. Wear sunglasses and a hat.

Let’s compare common sunscreen mistakes made by Seattle runners versus best practices for Utah:

• Seattle Mistake: Skipping sunscreen on cloudy days. Utah Best Practice: Always wear sunscreen, even on cloudy days.
• Seattle Mistake: Applying sunscreen only once before a run. Utah Best Practice: Reapply sunscreen every two hours, or more often if sweating.
• Seattle Mistake: Using a low SPF sunscreen. Utah Best Practice: Use a broad-spectrum sunscreen with an SPF of at least 50.
• Seattle Mistake: Forgetting to protect lips. Utah Best Practice: Use a lip balm with SPF 30 or higher.
• Seattle Mistake: Not using sweat-resistant sunscreen. Utah Best Practice: Use a sweat-resistant and water-resistant sunscreen.

Remember, protecting your skin is an investment in your long-term health.

Don’t let the Utah sun ruin your run.

Be proactive, be diligent, and enjoy the beautiful trails safely.

Think of sunscreen as essential as your running shoes when you’re in Utah.

It’s not an option; it’s a necessity.

So, Seattle runners, pack your sunscreen, apply it liberally, and get ready to experience the beauty of Utah’s trails, safely and responsibly.

Your skin will thank you.
