**Santa Fe's SPF: Altitude Lies Burning Summer Lasers?**
By Franklin Everett ShawThe sun in Santa Fe feels different. It’s not just a feeling; it’s a reality backed by science. Many visitors and new residents quickly learn this lesson the hard way, often with a painful sunburn as their souvenir. But understanding why Santa Fe’s sun is so intense and how to protect yourself can make all the difference in enjoying this beautiful city without risking your health.
Santa Fe, New Mexico, sits at an elevation of approximately 7,200 feet (2,194 meters) above sea level. This high altitude is the primary reason the sun feels so much stronger. The atmosphere acts as a filter, absorbing a portion of the sun’s harmful ultraviolet (UV) radiation. At higher altitudes, there’s less atmosphere to filter out these rays.
For every 1,000 feet of elevation gain, UV radiation increases by approximately 4-5%. This means that in Santa Fe, you’re exposed to roughly 25-35% more UV radiation than you would be at sea level. That’s a significant difference!
The thinner atmosphere also means that the sun’s rays travel a shorter distance to reach you. This shorter path results in less scattering and absorption of UV radiation, leading to a more direct and intense exposure.
Beyond altitude, Santa Fe’s dry climate contributes to the intensity of the sun. Humidity can absorb some UV radiation, but the arid conditions in Santa Fe mean there’s less moisture in the air to provide this natural protection.
The sun’s rays also reflect off surfaces like snow, water, and even sand. While Santa Fe isn’t known for its beaches, the light-colored adobe buildings and surrounding desert landscape can reflect a significant amount of UV radiation, increasing your overall exposure.
So, what can you do to protect yourself from Santa Fe’s intense sun? The answer lies in a combination of smart habits and the right products.
First and foremost, sunscreen is non-negotiable. But not just any sunscreen will do. You need a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum means it protects against both UVA and UVB rays.
SPF, or Sun Protection Factor, measures how well a sunscreen protects you from UVB rays, which are the primary cause of sunburn. However, UVA rays also contribute to skin damage, including premature aging and skin cancer.
Look for sunscreens that contain ingredients like zinc oxide or titanium dioxide. These are mineral sunscreens that create a physical barrier on your skin, reflecting UV rays away. They are also generally considered safer for sensitive skin and the environment.
Chemical sunscreens, on the other hand, absorb UV radiation. Common chemical sunscreen ingredients include avobenzone, octinoxate, and oxybenzone. While effective, some of these ingredients have been linked to hormone disruption and coral reef damage.
Regardless of the type of sunscreen you choose, application is key. Apply sunscreen liberally at least 15-30 minutes before sun exposure. Don’t skimp! Most people don’t use enough sunscreen, which significantly reduces its effectiveness.
A good rule of thumb is to use about one ounce (a shot glass full) of sunscreen to cover your entire body. Pay attention to often-missed areas like your ears, neck, and the tops of your feet.
Reapplication is just as important as the initial application. Sunscreen wears off over time, especially if you’re sweating or swimming. Reapply sunscreen every two hours, or immediately after swimming or excessive sweating.
Finding the right sunscreen in Santa Fe is relatively easy. Major drugstores like Walgreens and CVS, as well as grocery stores like Albertsons and Trader Joe’s, carry a wide variety of sunscreens. Local health food stores like La Montanita Co-op also offer a selection of natural and mineral-based sunscreens.
Some specific sunscreen brands readily available in Santa Fe that are worth considering include:
- EltaMD UV Clear Broad-Spectrum SPF 46: This is a popular choice among dermatologists and is known for being gentle on sensitive skin. It’s available at many local skincare clinics and some drugstores.
- Blue Lizard Australian Sunscreen: This brand is known for its mineral-based formulas and is readily available at most drugstores. The bottle even changes color in UV light, reminding you to reapply.
- Thinksport Safe Sunscreen SPF 50+: This is another mineral-based option that’s popular for its water resistance and reef-friendly formula. You can find it at many health food stores and some drugstores.
Beyond sunscreen, protective clothing is another essential tool in your sun protection arsenal. Wear long sleeves, pants, and a wide-brimmed hat whenever possible.
Look for clothing with a UPF (Ultraviolet Protection Factor) rating. UPF indicates how much UV radiation the fabric blocks. A UPF of 50 means that the fabric blocks 98% of UV rays.
Sunglasses are also crucial for protecting your eyes from sun damage. Choose sunglasses that block 100% of UVA and UVB rays.
Even on cloudy days, UV radiation can penetrate through the clouds. Don’t be fooled into thinking you don’t need sun protection just because the sun isn’t shining brightly.
Timing is also important. The sun’s rays are strongest between 10 a.m. and 4 p.m. Try to limit your sun exposure during these peak hours. If you must be outside, seek shade whenever possible.
Staying hydrated is also important for skin health. Drink plenty of water throughout the day to keep your skin hydrated and healthy.
Adapting your skincare routine to Santa Fe’s climate is also essential. The dry air can quickly dehydrate your skin, making it more susceptible to sun damage.
Use a gentle cleanser and a rich moisturizer to keep your skin hydrated. Consider adding a hydrating serum or facial oil to your routine.
Exfoliating regularly can help remove dead skin cells and improve the absorption of your moisturizer. However, be careful not to over-exfoliate, as this can irritate your skin and make it more sensitive to the sun.
Finally, be aware of medications that can increase your sun sensitivity. Certain antibiotics, acne medications, and other drugs can make your skin more likely to burn. Talk to your doctor or pharmacist about any medications you’re taking and whether they can increase your sun sensitivity.
Living in or visiting Santa Fe is a wonderful experience. The city’s unique culture, stunning landscapes, and vibrant art scene are truly captivating. But it’s important to remember that the sun in Santa Fe is not to be taken lightly. By understanding the risks and taking the necessary precautions, you can enjoy all that Santa Fe has to offer without compromising your health. Remember, protecting your skin is an investment in your long-term well-being.
