More than two million new cases of skin cancer are diagnosed each year, and the number is growing. Skin cancer is a major public health issue, and with proper precautions you can decrease your risk considerably. Hopefully this information on sun safety will help you, whether you are a Warfighter or dependent, stay safe during all outdoor activities!
Ultraviolet radiation (UVR) has been identified as the most important risk factor for both melanoma and non-melanoma skin cancer. Exposure to UVR weakens the skin’s elasticity and can result in sagging cheeks, deeper facial wrinkles, skin discoloration, burn, skin aging, photosensitivity, and cancer. Taking steps to safeguard yourself is crucial, especially when participating in outdoor activities or exercising.
Sweating increases the skin’s sensitivity to the sun’s rays, magnifying the risk of sunburn and skin damage. Athletes who practice outdoor sports have been found to be at increased risk for skin cancer. Remember—the weather does not have to be sunny and hot for you to get sun damage. Ultraviolet rays penetrate clouds, exposing you to 80% of the UVR. Even skiers and mountain climbers are at risk for sun exposure and skin cancer because of the stronger UVR at altitude.
Follow these precautions from the Occupational Safety and Health Administration (OSHA) whether training for the PRT, patrolling, road marching, or participating in a summer league softball game:
Avoid burning. Avoid sun tanning. Also, try to avoid sun exposure during midday (11 a.m. to 3 p.m.) when the rays are the strongest.
Seek shade. When possible, especially during midday, seek shade under a tree or tent.
Cover up. Wear protective clothing, including hats, long-sleeved shirts, and pants when going outdoors. Keep in mind protection decreases when clothes are wet.
Use extra caution near water, snow, and sand. Ultraviolet rays can reflect off of these surfaces, which can increase your chance of sun exposure and skin damage.
Apply sunscreen. Use water-resistant sunscreen and apply 15-30 minutes prior to sun exposure to allow for it to absorb. Also, reapply after swimming, sweating, or toweling off. Be sure to take a look at the new FDA regulations regarding sunscreens and their effectiveness.
Wear sunglasses. Protect your eyes when working, driving, participating in sports, taking a walk, or running an errand. Solar ultraviolet B radiation can cause an increased risk of cataracts and cancer of the skin around the eye without proper cover.
It’s always important to remember hydration when engaging in outdoor activities as well! HPRC has useful tips on hydration and the consumption of sports drinks and caffeine during exercise in the heat.
Your sunscreen has an expiration date—have you checked it lately? It’s meant to last up to about three years; after that, the active ingredients start to deteriorate, making it less effective and leaving you vulnerable to sunburn and sun damage. Ideally, you should be using your sunscreen often enough that a bottle doesn’t last through the summer. If that’s not the case, check the bottle you’re currently using—if it’s old, throw it out. If you buy sunscreen that has the expiration printed only on the box or wrapper, write the date somewhere on the bottle itself with a permanent marker. Practice safe sun this summer to keep you and your family healthy and happy!
It’s always a good idea to replace old sunscreen, but next summer you’ll have even more reason to do so. Sunscreen companies have until December 2012 to revise their labels to abide by FDA’s new guidelines. The new labels will prevent manufacturers from false advertising with respect to the level of protection they provide. Sunscreens also will have to go through FDA’s testing to determine their effectiveness.
The new guidelines are summarized below:
Broad-spectrum designation: Sunscreens will have to pass FDA’s broad-spectrum test to be labeled as such. This confirms the sunscreen protects against both ultraviolet A and B rays, both of which contribute to skin cancer and early skin aging.
Use claim: Only broad-spectrum sunscreens with an SPF of 15 or higher can claim to reduce skin cancer risk and early skin aging if used as directed. Sunscreens with SPFs between 2 and 14 can claim only to help prevent sunburn.
Waterproof, sweatproof, and sunblock claims: Sunscreens will no longer be able to claim they are waterproof, sweat-proof, or “sunblock,” since those claims over-exaggerate their effectiveness. No sunscreen is waterproof or sweat-proof without the proper reapplication. Also, sunscreens do not “block” the sun; they reduce the penetration of the ultraviolet rays.
Water-resistance claims: Any sunscreen with a “water-resistant” label must indicate whether it is effective for 40 or 80 minutes while swimming or sweating.
Drug facts: All sunscreens must include standard drug-facts information on the label.
