Taos Tourists: Altitude Sun Lies About SPF?
By Franklin Everett ShawThe crisp mountain air bites at your cheeks, a stark contrast to the sun blazing down from a seemingly cloudless sky. You’re in Taos, New Mexico, a land of stunning vistas and deceptively potent UV radiation. That “high-altitude glow” you’re chasing could quickly turn into a painful burn if you’re not careful. Forget what you think you know about SPF; up here, the rules are different.
The sun in Taos doesn’t play around. At an elevation of nearly 7,000 feet, the atmosphere is thinner, filtering out less of the sun’s harmful ultraviolet (UV) rays. This means you’re exposed to significantly more UV radiation than you would be at sea level.
SPF, or Sun Protection Factor, is a measure of how well a sunscreen protects you from UVB rays, the primary cause of sunburn. It’s not a linear scale. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%.
Many tourists mistakenly believe that a higher SPF allows them to stay in the sun longer without reapplying. This is a dangerous misconception. SPF primarily indicates the amount of UVB protection, not the duration.
In Taos, the intensity of UV radiation is so high that even a high SPF sunscreen can be overwhelmed if not applied correctly and reapplied frequently. Think of it like this: SPF is your shield, but the sun in Taos is wielding a laser.
So, what’s the right approach? Let’s break it down.
First, choose the right SPF. While SPF 30 is often recommended as a baseline, in Taos, you should start with SPF 50 or higher, especially if you have fair skin or are planning to spend extended periods outdoors. Don’t skimp.
Second, apply generously. Most people don’t use enough sunscreen. You should aim for about one ounce (a shot glass full) to cover your entire body. Don’t forget often-missed areas like your ears, the back of your neck, and the tops of your feet.
Third, reapply religiously. Sunscreen needs to be reapplied every two hours, or more frequently if you’re sweating or swimming. Set a timer on your phone to remind you. This is non-negotiable in Taos.
Fourth, consider the reflective surfaces. Snow, in particular, reflects UV radiation, effectively doubling your exposure. If you’re skiing or snowboarding, be extra vigilant about sunscreen application and wear protective clothing.
Fifth, don’t rely solely on sunscreen. Protective clothing, such as long sleeves, pants, and wide-brimmed hats, can significantly reduce your sun exposure. Sunglasses are also essential to protect your eyes from UV damage.
Sixth, understand the UV Index. Check the daily UV Index forecast. When the UV Index is high (7 or above), take extra precautions, even if it’s cloudy. Clouds don’t block all UV radiation.
Let’s consider a real-world scenario: You’re planning a day of hiking in the Taos Ski Valley during the summer. The UV Index is predicted to be 9. You apply SPF 30 sunscreen in the morning, thinking it will be sufficient. By midday, you’re already feeling the burn.
What went wrong? Several things. You chose an insufficient SPF, didn’t apply enough sunscreen, and didn’t reapply frequently enough. You also didn’t wear protective clothing or sunglasses.
A better approach would have been to start with SPF 50 or higher, apply a generous amount of sunscreen 30 minutes before heading out, reapply every two hours, wear a long-sleeved shirt and pants, a wide-brimmed hat, and sunglasses.
Another common pitfall is assuming that sunscreen applied in the morning will last all day. Sunscreen degrades over time, especially when exposed to sunlight and sweat. Reapplication is crucial.
Many people also underestimate the importance of lip balm with SPF. Lips are particularly vulnerable to sun damage.
Here’s a step-by-step guide to effective sun protection in Taos:
- Check the UV Index forecast.
- Choose an SPF 50 or higher sunscreen.
- Apply generously 30 minutes before sun exposure.
- Wear protective clothing, a hat, and sunglasses.
- Reapply sunscreen every two hours, or more frequently if sweating or swimming.
- Use lip balm with SPF.
- Seek shade during peak sun hours (10 AM to 4 PM).
Don’t let the intense sun of Taos ruin your vacation. By understanding the unique challenges of high-altitude sun exposure and taking the necessary precautions, you can enjoy the beauty of this region safely and responsibly. Remember, prevention is always better than cure when it comes to sun damage.
