Protect Your Skin All Year Long
According to the Skin Cancer Foundation, an estimated 90 percent of skin aging is caused by the sun. However, sun exposure not only affects your appearance but can also pose a threat to your health. In fact, having five or more sunburns doubles your risk of melanoma, which is one of the more dangerous types of skin cancer. Keeping sun protection in mind during the fall and throughout the year is crucial for reducing the risk of developing skin cancer.
While some individuals are more prone to sunburn than others, anyone can get burned. The American Academy of Dermatology recommends that everyone use a water-resistant broad-spectrum sunscreen with an SPF of 30 or higher. Most over-the-counter sunscreens nowadays meet these criteria. This practice helps minimize the risk of premature aging, sun damage, and the chances of developing skin cancer.
Here are some common myths about sun exposure:
- Myth: I’m safe from the sun’s rays in my car. False. While window glass filters the majority of UVB rays, longer wavelength UVA rays can penetrate and reach your skin. Although most windshields are treated to filter out UVA, side and rear windows usually aren't. You can either install window film for protection or wear sunscreen as you would outdoors.
- Myth: If you can’t see the sun through the clouds, you’re not at risk for a sunburn. False. Ultraviolet rays can penetrate through clouds, rain, and fog. Also, keep in mind that summer storms can clear up rapidly.
- Myth: I work indoors, so I don’t need sunscreen. False. Similar to being in a car, UVA rays can penetrate glass. If you're near a window, these rays can reach you. Moreover, the time spent going to and from your car and being in your car can accumulate.
- Myth: A light pink sunburn isn’t so bad. Regardless of how mild it is, every burn indicates skin damage that can lead to premature aging and skin cancer.
- Myth: I don’t need sunscreen in winter. False. Even though the UV index is lower in winter months in Michigan, UV rays reflect off ice and snow, effectively hitting your skin a second time.
Skin damage accumulates over time. The more you burn and tan, the higher your risk of skin cancer becomes. You can mitigate this risk by following these sun safety guidelines:
- Cover up: Wear sun-protective clothing and a broad-brimmed hat to create a barrier against UV rays.
- Seek shade: Especially during peak hours of 10 a.m. to 4 p.m.
- Apply sunscreen: Use a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher.
- Mind windows: Whether in cars or buildings, be mindful of sun exposure through windows.
- Avoid tanning beds: Indoor tanning, even just once, increases the risk of various skin cancers, including melanoma.
If you spend a lot of time in the sun or have had multiple sunburns, regular skin examinations by a health care professional are important. If you notice new, changing, or suspicious spots on your skin, or experience itching or bleeding, consult your health care provider.
