Skin cancer is the most common form of cancer in the country. Each year, more than 1 million people in the United States are diagnosed with it. And yet, when the sun’s out, we are so often drawn to it and run outside without taking the proper precautions.

It’s no secret that the sun’s rays can be harmful. Sunlight contains ultraviolet radiation, which can cause skin cancer. You don’t have become a hermit and hide from sunlight like a vampire. Cancer care nurse Josette Snyder, RN, MSN, AOCN, offers steps you can take to reduce your risk of skin damage from the sun — and skin cancer.
Sunscreen is an important part of sun protection and should be a staple in your medicine cabinet during the summer months. Look for a product that provides a sun protection factor (SPF) of 30 or higher, and is broad spectrum, which means it protects you from both UVA and UVB rays.
“About 30 minutes before you go outside, apply a thick coating – and be sure to reapply frequently, because all sunscreens break down in the sun after two to three hours,” explains Snyder. If you go in the water, reapply sunscreen after you dry off, even if it’s a water-resistant sunscreen. It’s a good rule of thumb to reapply sunscreen every two hours, even if it says “all day protection.”
Be sure to apply sunscreen to places in places often missed. These include your ears, the tops of your feet, and your scalp.
Stay in the shade
Avoid the sun’s rays, especially during the midday hours of 10 a.m. to 3 p.m., when the sun is highest and its rays are most direct. Ideally, seek shelter under an umbrella, tree or other shade before you need relief from its rays. If you’re in sunlight, keep an eye out for your skin turning pink or becoming sensitive. By this point, however, damage is already happening to your skin.
Ultraviolet rays still can reach you in the shade when you’re outside, so you still need to use sunscreen or wear protective clothing.
Cover your arms and legs
Long-sleeved shirts and long pants and skirts can protect you from UV rays. Although light-colored, loosely woven clothing is popular during the warm months, you may be surprised to learn that garments that are dark-colored or made from tightly woven fabric give more protection against the sun. The tightly woven fabric physically blocks the sun’s rays, while the dark color absorbs them. Also, wet clothing offers much less UV protection than dry.
“A typical T-shirt has a SPF rating lower than 15, so don’t rely solely on clothing – use other types of protection as well, such as sunscreen,” says Snyder.Several companies sell clothing with ultraviolet protection factor (UPF), a sun protective factor built into the clothing, which includes swimwear, T-shirts and hats.
Wear a hat
Choose a hat with a wide brim that goes all the way around your head to shade your face, ears and neck. A tightly woven fabric, such as canvas, is best, and a darker hat may offer more UV protection.Avoid straw hats with holes that let sunlight through. “If you wear a baseball cap, protect your ears and the back of your neck by wearing clothing that covers those areas, use a sunscreen with an SPF of at least 30, or stay in the shade,” Snyder says
Sunglasses not only protect your eyes from UV rays and reduce the risk of cataracts, but they also protect the tender skin around your eyes from sun exposure.
When you’re shopping for sunglasses, look for lenses that block UV rays, Snyder recommends Most sunglasses sold in the United States, regardless of cost, meet this standard. “Wrap-around sunglasses work best because they block UV rays that can come in from the side,” she notes.
Don’t use tanning beds
It’s widely known that tanning beds are linked to skin cancers, including melanoma – the deadliest type of skin cancer.
People who use tanning beds are 2.5 times more likely to develop squamous cell carcinoma and 1.5 times more likely to develop basal cell carcinoma. And it’s not just your skin that’s at risk: Exposure to the UV radiation that tanning beds emit also can cause cataracts and cancers of your eyes. Snyder says even occasional sunbed use almost triples your chances of developing melanoma. Young people — including teenagers — are especially sensitive to the UV rays that tanning beds emit.
If you really prefer the “healthy” glow of tanned skin, there are many sunless tanners and bronzers available that create that sun-kissed look without the risk of skin cancer. These are cosmetics applied to the skin like a cream or spray and can provide a temporary, artificial tan. The only color additive currently approved by FDA for this purpose is dihydroxyacetone (DHA).
“If you do use a sunless tanner, be sure to still apply sunscreen when going out in the sun as most sunless tanning products don’t contain sunscreen,” she says.
