Wellness@Work: How to protect yourself from UV rays

Spending more time outside in the summer usually makes us more concerned about protecting our skin from the sun’s harsh rays, but wearing sunscreen should really be part of a year-round skin care regimen.

Exposure to ultraviolet (UV) rays comes from natural and artificial sources, and it’s the cause of most skin cancers. Perhaps surprisingly, it isn’t just limited to time spent at the beach or outside relaxing by the pool.

July is Ultraviolet Safety Month, an opportunity to educate yourself on all the ways – especially the unlikely ones – you can be exposed to harmful UV rays and how you can protect yourself against them.

In addition to skin cancers, UV exposure can cause premature aging, sun damage, sunburn, eye injury, cataracts, and more. Too much UV light can lead to a weakened immune system, which can result in lower vaccine effectiveness or difficulty in fighting off infection.

Yes, it’s important to apply (and reapply) a broad-spectrum sunscreen, limit or avoid sun exposure during the hottest part of the day, wear protective clothing – including a broad-brimmed hat and sunglasses – and drink plenty of water.

But what about when summer is over? The threat of UV exposure still lingers. Here are some common ways you might be susceptible to UV rays without even realizing it.

• At home or work: If you sit or work anywhere within several feet of a window, UVA rays – the main cause of premature aging – will reach you. They, along with UVB rays, contribute to the development of skin cancer, but you can do several things to protect yourself, like wearing a broad-spectrum sunscreen or using blinds to help reduce or block UV radiation. You can also position furniture so you are less exposed to sunlight.
• While traveling: Time behind the wheel can add up, especially if you are driving a long distance. Front windshields filter out most UVA rays, but side and rear windows typically don’t. Consider installing protective film on your windows to shield yourself, but make sure it is compliant with local regulations. If you are flying to your destination, note that the sun’s rays may be even stronger through airplane windows. Wearing protective clothing and sunscreen is always a good option.
• On rainy days: Rainy or overcast days don’t provide the protection you may think they do. UV rays can penetrate clouds, rain, fog, etc., so don’t skip sunscreen or protective clothing. Scattered summer showers, like the ones we experience on the Gulf Coast, often pass through quickly, so the likelihood of being exposed to the sun is still high. Outside, UVB rays are stronger and can lead to more damage.
• At the nail salon: Treating yourself to a mani-pedi can be a welcome indulgence, but be aware of UV exposure from the dryers. Whether they are called UV lamps or LED lamps, these nail dryers emit UV radiation. For manicures, like gel manicures that require them, apply sunscreen to your hands or feet 20 minutes before they go under the dryer. For other treatments, allow your nails to dry naturally or use a small fan if available at the salon.
• On a mountain or higher elevation: UV radiation gets stronger the higher in elevation you go, and it increases 4% to 5% with every 1,000 feet above sea level. Of course, you’ll need your protective clothing and broad-spectrum sunscreen, and be aware that you will have to be just as vigilant about reapplying it at least every couple of hours because UV rays reflect off ice and snow to expose your skin a second time.

Keep in mind that you need to protect your eyes and lips, as well as your skin, from exposure to UV light. Various moisturizers, lipsticks, balms and foundations often contain sunscreen, but check the labels to be sure you are getting sun protection from them.
