Want to play it safe when enjoying fun-in-the-sun Scouting this summer? Here’s how to protect your body from harmful, cancer-causing UV rays.
Summer camp, high adventure trips, vacations at the beach — all offer exciting possibilities within the next few months. But though spending time outdoors is both healthy and refreshing, you can get too much of a good thing.
“We’re seeing an epidemic of skin cancers,” Dr. Rogers says. As a former volunteer Scouter, Dr. Rogers knows all about the benefits of outdoor exercise. “We don’t want people to stay in caves,” he says. “But they need to protect themselves. Every sunburn you avoid is good news.”
Most people realize they’re at risk on a sunny day at the beach, but what about those cool, cloudy days high in the mountains? Protect yourself there, too, Rogers recommends. The thinner air and glaring snow increase your risk of sunburn, even if there’s no sun in sight.
“It’s not just the sunlight coming down on you,” Dr. Rogers says. “It’s what’s reflected at you.” And because the strongest sunlight occurs between 10 A.M. and 4 P.M., be aware that those are the most dangerous times of the day.
In addition, some people with blue eyes, light skin, and light or red hair just face a greater risk.
UV-A and UV-B rays both cause sunburn, so you’ll notice when you’ve been overexposed. But UV-A rays are more insidious. “They penetrate more deeply,” says Dr. Rogers. “While they don’t cause immediate, visible damage, they cause long-term damage, including skin cancers.”
The American Academy of Dermatology recommends a SPF rating of at least 15. FDA regulations set
the maximum SPF rating at 30 (sun-screens above that can carry a rating of 30+). But don’t let a high SPF lull you into a false sense of security: Very few sunscreens provide all-day protection, and it’s always advisable to reapply sunscreen after exercise or swimming.
If you’re hoarding sunscreen from your trip to the Florida sea base five years ago, trash it. Sunscreens degrade over time, so it’s not only past the expiration date, it’s ineffective against UV-A rays.
You can also boost UV-A protection by using zinc oxide, titanium dioxide (the thick, white goop lifeguards wear on their nose), or the sunscreen avobenzone, which effectively blocks both UV-A and UV-B rays.
For maximum absorption, apply the recommended amount of sunscreen to dry skin 15 to 30 minutes before exposure. Ask someone to help apply it to hard-to-reach areas, and don’t overlook the back of your neck, your feet and toes, around your ears, and the backs of your knees. Also, choose a lip balm with the highest SPF you can find, especially if you are susceptible to cold sores, which can be exacerbated by exposure to the sun.
Desert dwellers dealing with blistering sun every day wear head-to-toe, loose-fitting robes that provide ventilation and shade. Follow their example by dressing in long pants and long sleeves. Choose clothing that moves easily without being so loose that it catches on rocks or branches.
To protect your face, neck, or ears, shade it with a hat with a wide brim (think Indiana Jones or a cowboy). An Australian-style, floppy brimmed bush hat or a Tilley hat make good picks, as does a Foreign Legion-style hat, with a visor in front and flap in back to protect your neck. Tilley hats also deliver maximum SPF protection besides shade. Experts don’t recommend baseball caps. No matter how you wear them, the brim only protects one side of your head.
Choose a light-colored hat that reflects more light and helps keep your head cool.
Medical evidence suggests that while long-term exposure to the sun can contribute to the formation of cataracts, short-term exposure is dangerous, too.
Look for glasses that fit snugly.
Mountaineering glasses have ventilated leather side flaps, which block light from coming in from the sides. In less severe environments, you can wear clip-on sunglasses over prescription eyewear, but at high altitudes, you need complete eye protection.
