Taos Tans: Altitude Lies Hiding Winter Harm?
By Franklin Everett ShawThe sun feels different in Taos. It’s not just the crisp mountain air; it’s a sharper, more intense light that seems to penetrate deeper. This isn’t your average beach vacation sun; it’s a high-altitude solar assault, and understanding how to defend against it is crucial for anyone living in or visiting this beautiful New Mexico town.
Taos, nestled in the Sangre de Cristo Mountains, sits at an elevation of nearly 7,000 feet. This altitude significantly reduces the atmosphere’s filtering effect on ultraviolet (UV) radiation.
UV exposure increases by approximately 4% to 5% for every 1,000 feet of elevation gain. That means Taos residents and visitors are exposed to roughly 28% to 35% more UV radiation than someone at sea level.
But the altitude is only half the battle. Snow, a common sight in Taos during the winter months, reflects up to 80% of UV radiation. This effectively doubles your exposure, hitting you from above and below.
So, what does this mean for your sunscreen? That SPF 30 you rely on at the beach might not cut it in Taos.
Let’s break down the science. SPF, or Sun Protection Factor, measures how long it takes for UVB radiation to redden skin with sunscreen compared to without sunscreen. An SPF of 30 blocks approximately 97% of UVB rays.
However, this protection is based on laboratory conditions, which don’t account for the increased intensity of UV radiation at high altitudes or the reflective properties of snow. In Taos, you need to think about SPF not just as a percentage blocker, but as a time extender.
Imagine your skin typically burns after 10 minutes of sun exposure without protection. An SPF 30 sunscreen should theoretically extend that to 300 minutes (10 minutes x 30 SPF). But because of the increased UV intensity in Taos, that 300 minutes could be significantly reduced, perhaps to 200 minutes or even less.
Therefore, a higher SPF is essential. Aim for SPF 50 or higher, especially during peak sunlight hours (10 AM to 4 PM) and on snowy days.
Don’t skimp on application. Most people don’t apply enough sunscreen. You should use about one ounce (a shot glass full) to cover your entire body.
Reapplication is also critical. Sunscreen effectiveness decreases over time, especially when sweating or participating in winter sports. Reapply every two hours, or more frequently if you’re active.
Choose a broad-spectrum sunscreen. This means it protects against both UVA and UVB rays. UVA rays contribute to premature aging and skin cancer, while UVB rays are the primary cause of sunburn.
Look for sunscreens containing zinc oxide or titanium dioxide. These mineral sunscreens are generally considered safer and more effective than chemical sunscreens.
Beyond sunscreen, protective clothing is your next line of defense. Long sleeves, pants, and wide-brimmed hats can significantly reduce UV exposure.
Consider investing in clothing with a UPF (Ultraviolet Protection Factor) rating. UPF indicates how much UV radiation can penetrate the fabric. A UPF of 50 allows only 1/50th of the sun’s UV rays to pass through.
Sunglasses are non-negotiable. The sun’s glare off the snow can cause serious eye damage, including cataracts and photokeratitis (snow blindness). Choose sunglasses that block 100% of UVA and UVB rays.
Don’t forget your lips! Lips are particularly vulnerable to sun damage. Use a lip balm with an SPF of 30 or higher.
Even on cloudy days, UV radiation can penetrate clouds. Don’t let overcast skies lull you into a false sense of security.
A common mistake is thinking that you’re protected inside a car or near a window. Glass blocks UVB rays but allows UVA rays to pass through.
Another pitfall is neglecting areas like the ears, neck, and the backs of your hands. These areas are often overlooked during sunscreen application.
Acclimatization to the altitude doesn’t equal acclimatization to the sun. Your body may adjust to the lower oxygen levels, but it won’t develop a natural resistance to UV radiation.
Consider the time of year. While sun protection is crucial year-round, it’s especially important during the winter months in Taos due to the snow’s reflective properties.
Think about your activities. Skiing, snowboarding, and other winter sports increase your exposure to UV radiation due to the altitude and snow reflection.
Children are more susceptible to sun damage than adults. Their skin is thinner and more delicate. Take extra precautions to protect children from the sun.
Regular skin checks are essential. Monitor your skin for any new moles or changes in existing moles. Consult a dermatologist if you have any concerns.
Living in or visiting Taos offers unparalleled opportunities for outdoor recreation. But it also demands a heightened awareness of sun safety.
By understanding the increased UV exposure at high altitudes and taking appropriate precautions, you can enjoy the beauty of Taos without compromising your health. Remember, consistent and diligent sun protection is the key to preventing sun damage and maintaining healthy skin for years to come.
