The days are longer, the nights are shorter and the air fills with possibility in the summer!

Whatever adventures lie ahead, whether you’re at home or away, always remember to protect your skin—and not just when you’re at the pool or beach. The UV rays don’t care whether you’re playing golf, walking to the grocery store or working outside: according to the Centers for Disease Control and Prevention, overexposure to the sun over the years can lead to cancer, premature aging of the skin, age spots and wrinkles. For health purposes—and to help yourself age more gracefully—read on for more do’s and don’ts when it comes to sun safety.

1. Do slather on the sunscreen.

Make sure it’s broad spectrum sunscreen that blocks UVA as well as UVB rays, and has an SPF of at least 15 or higher, per the CDC. And be sure and put it on before you go outside for the best possible protection.

2. Do avoid the sun as much as you can.

UV rays are strongest between 10 a.m. and 4 p.m., according to the American Cancer Society. If you’re able to, plan on avoiding the sun during those hours and instead schedule outdoor activities in the morning and evening to best protect your skin. When you are outside, try and stay in the shade when possible. And in addition to a broad-brimmed hat and sunglasses, wear clothing that can protect your skin. The CDC says that dark clothes made from tightly woven fabric offer the best protection. Of course, on the hottest of days that might not sound enticing, but it’s at least something to keep in mind!

3. Do protect babies from the sun.

If you have an infant, avoid spending time with them in direct sunlight until they’re at least six months old, suggests the FDA and American Academy of Pediatrics. In the meantime, consider clothing, hats, umbrellas, stroller shades, a pop-up tent, or whatever makes sense to shield the child’s skin. And when your baby reaches six months of age, talk with your pediatrician about what type of sunscreen to use, and how much sun is too much.

4. Do pay attention to the expiration date on your sunscreen.

Did you know the Food and Drug Administration (FDA) regulates sunscreen? That means there are some rules applied to sun-protection products, and one of those rules is that sunscreen must retain its original strength for at least three years. When you purchase it, see if the bottle has an expiration date. If not, add three years to the date of purchase and write it in marker on the bottle.

5. Do make an appointment with a dermatologist for a skin cancer screening.

Skin cancer is the most common kind of cancer in the United States, according to the Cleveland Clinic. A dermatologist is trained to spot cancer early, and that could help with treatment. When you make an appointment for a skin cancer screening, a dermatologist will examine you from head to toe (and even between your toes) looking for anything suspicious. The Cleveland Clinic recommends annual screenings for anyone who has had: a history of melanoma, skin cancer or precancerous spots; an immediate family member with a history of melanoma; lots of moles or atypical moles; significant sun exposure, a history of blistering sun burns or used tanning beds; received an organ via transplant.

6. Do know the signs of heat stroke.

Summertime heat is a risk to always keep in mind, whether you’re playing tennis, gardening or just lounging with a book outside. The warning signs of heat stroke are varied, and should always be taken seriously. The CDC lists those signs as high body temperature; red, hot, dry or damp skin; fast, strong pulse; headache; dizziness; nausea; confusion and passing out. If you suspect someone is suffering from heat stroke, call 911 and move them out of the sun to a cooler place. Cover them with cool towels, or run a cool bath. It sounds counterintuitive, but don’t give them water to drink as you wait for medical help.  

7. Don’t forget to reapply sunscreen.

There’s no one-and-done when it comes to slathering on sunscreen—even if your sunscreen is waterproof. The American Academy of Dermatology Association (AAD) says when you’re outdoors, you should reapply sunscreen every two hours; more frequently if you’re sweating, swimming or getting wet.

8. Don’t assume your skin tone will protect you.

While people with more melanin in their skin might not burn as easily, they can still get sun damage and skin cancer. According to AAD, everyone should take action and protect their skin, regardless of color.

9. Don’t let the clouds fool you.

UV rays can find you through the clouds. Protect your skin, even when on those dreary, gray days. If you’re going outside, always put on sunscreen.

10. Don’t neglect your lips (and other parts).

Lips can burn, too! Use a balm or lipstick with sunscreen in it. And, while we’re at it, don’t forget other often-forgotten body parts, like your ears, your feet, your neck, your hands and the top of your head.

11. Don’t use tanning beds or sunlamps.

Tanning beds and sunlamps rely on UV rays, which could damage and age your skin, and even lead to cancer.

12. Don’t hesitate to talk to your doctor about any changes in your skin.

Skin cancer can take a number of appearances, some of which are subtle. According to AAD, it could be a changing or irregular looking mole, a dome-shaped growth, a scaly patch of skin, a sore that won’t heal or keeps returning, or a black or brown streak under a fingernail or toenail. If you’re worried about something you see on your skin—especially something that changes, differs from others, itches or bleeds—make an appointment with a dermatologist.

Summertime is for family vacations, trips to the lake, leaps through the sprinkler and sticky, drippy popsicles. It’s a time for new experiences and making memories. To make the most of all of the above, be sure and take the necessary steps to protect your skin. It only takes a few minutes to keep yourself safe. Doing so could make an impact on your health years down the line. Not to mention fewer wrinkles, as you age gorgeously.
