As the weather warms up and everyone starts to head outside, we need to remember to be kind to our skin. One of the most important ways to take care of your skin is to protect it from the sun. While soaking up some rays can be good for the body, by increasing the amount of Vitamin D, excessive exposure can cause wrinkles and age spots, and can increase the risk of skin cancer (1). Research shows a strong dose-response relationship between UV exposure and skin cancer, the more time you spend tanning, the higher the risk of developing melanoma and other types of skin cancer (2).
Exposure to UV is not the only way source of irreparable damage to the skin. Tanning beds, which rely mainly on UVA light to create a tan, have been classified by The World Health Organization’s International Agency for Research on Cancer (IARC) as carcinogenic to humans (2). In fact, studies show that occasional use of tanning beds triples the risk of developing melanoma.
Fortunately, there are simple approaches to help protect from damaging UV rays. The best way to protect yourself from UVA exposure is to not use tanning beds. Tanning beds are dangerous, and offer virtually no positive health benefits.
Here are three ways to protect yourself from damage caused by excess exposure to the sun(1):
- Wear sunscreen when outdoors with at least 15 SPF and reapply every two hours. Regular daily use of a sunscreen with SPF 15 or higher reduces the risk of developing melanoma by 50 percent (3).
- Seek shade or shelter during from about 10 am to 2 pm when the sun’s rays are strongest.
- Wear protective clothing when you are outdoors for prolonged periods of time.
As you head outside this summer, remember to protect yourself to ensure that your skin, and your body, stays healthy and happy!
