UV Safety — It’s Not Just Skin Deep


July is here, ushering in the heart of the summer season. It’s the perfect time to celebrate with fireworks displays, barbecues, picnics, and carefree days at the beach. It’s also the perfect time to think about how to protect ourselves while out in the sun. Ultraviolet Safety Awareness Month highlights the importance of protecting our eyes, lips, and skin from the harmful effects of UV rays.

Let’s start with a few basics. The American Cancer Society recommends the following safety precautions:


Cover up: When you are out, wear clothing that covers as much skin as possible and a wide-brimmed hat to protect your head and face.


Use a broad-spectrum sunscreen with an SPF of at least 30. Apply generously at least every 2 hours, as well as after swimming or sweating. Dynarex offers a full line of premium skin care products, including Dynarex We Care SPF 30 Sunscreen, to keep you protected.


Protect your eyes with wrap-around sunglasses that block at least 99% of UV light.




While these guidelines may seem simple, there are still many commonly held misconceptions about UV rays and how they affect us. Try testing your knowledge with this simple true-or-false quiz: 


  • True or False? You can’t get sun damage through glass such as windows or windshields.

    False: Glass does not filter out all UV rays, so your skin can still get damaged. That’s why experts recommend you wear SPF 30 sunscreen every day, and not just when you are outside. Be sure to use sunscreen before getting in the car for a drive, especially when traveling long distances.


  • True or False? You don’t need to wear sunscreen after 4:00 p.m.

    False: UV rays can damage your skin any time during the day. While the sun’s UV rays are strongest from 10:00 a.m. to 4:00 p.m., it’s best to practice sun safety during all daylight hours.


  • True or False? Once the weather gets cooler, it’s fine to stop wearing sunscreen.

    False: Temperature itself does not affect UV rays. Even during winter, it’s important to practice sun safety during outdoor activities like skiing, sledding, or snowmobiling. Keep in mind that UV rays are stronger at higher elevations and reflect off snow.


  • True or False? Your eyes can get sunburned as well as your skin.

    True: Sunburned eyes are a real thing! They can become red, dry and painful. Chronic eye exposure can even cause serious permanent damage—even blindness. According to the American Academy of Ophthalmology, “UV radiation, whether from natural sunlight or indoor artificial rays, can damage the eye's surface tissues as well as the cornea and lens."


  • True or False? The negative effects of sun exposure wear off quickly.

    False: Sun exposure accumulates over time. Many people think about sun protection only when they are at the beach or pool. But UV exposure happens every time you are in the sun and adds up day after day.


  • True or False? UV rays have no effect on your immune system.

    False: Scientists have found that overexposure to UV radiation may suppress the body’s immune system and the skin’s natural defenses. For example, the skin normally mounts a defense against foreign invaders such as cancers and infections. But overexposure to UV radiation can weaken the immune system, undermining the skin’s ability to protect against these intruders.
