KNOXVILLE – It’s natural to want to get out in the sun during warm summer days. It should also be second nature to take steps to protect your skin from the sun when you go outside.
Ultraviolet (UV) rays – from the sun and other sources like tanning beds – are the #1 cause of skin cancer. Too much exposure can also cause sunburn, eye damage, and premature wrinkles.
But shielding your skin with clothing, broad-spectrum sunscreen with a sun protection factor (SPF) of 30 or higher, and staying in the shade can help lower your risk.
Knoxville Hospital & Clinics invites you and your family to attend a free skin cancer screening on June 19-23, from 5-7. An appointment is required. To make an appointment, call 641-842-7211. Our goal is to detect skin cancer early and raise awareness about melanoma, the deadliest form of skin cancer. Screenings take place in a private setting and consist of a brief skin assessment by a medical professional. Typically, only exposed areas such as your face, arms, hands, neck, and feet will be examined. Screenings are open to adults and children. Recommended screening attire: shorts and t-shirt. Skin cancer screenings are not intended to take the place of comprehensive skin exams. For a more in-depth examination, please schedule an appointment with your dermatologist.
When you are outdoors, take these steps to stay sun safe:
- Cover up: When you are out in the sun, wear clothing and a wide-brimmed hat to protect as much skin as possible. Protect your eyes with sunglasses that block at least 99% of UV light.
- Use a broad-spectrum sunscreen with an SPF of 30 or higher: Reapply at least every 2 hours, as well as after swimming or sweating.
- Seek shade: Limit your direct exposure to the sun, especially between 10 a.m. and 4 p.m., when UV rays are strongest.
- Avoid tanning beds and sunlamps: Both can cause serious long-term skin damage and contribute to skin cancer.
While you should use sunscreen every day of the year, it’s even more important during the summer, when the days are longer, the sun is stronger, and it’s easier to spend more time outdoors. When choosing sunscreen, read the label before you buy. US Food and Drug Administration regulations require the labels to follow certain guidelines:
- Choose a sunscreen with “broad-spectrum” protection. Sunscreens with this label protect against both UVA and UVB rays. All sunscreen products protect against UVB rays, which are the main cause of sunburn. But UVA rays also contribute to skin cancer and premature aging. Only products that pass a test can be labeled “broad spectrum.” Products that aren’t broad spectrum must carry a warning that they only protect against sunburn, not skin cancer or skin aging.
- Choose a sunscreen with a sun protection factor (SPF) of 30or higher. The SPF number is the level of protection the sunscreen provides against UVB rays. Higher SPF numbers do mean more protection, but the higher you go, the smaller the difference becomes. SPF 15 sunscreens filter out about 93% of UVB rays, while SPF 30 sunscreens filter out about 97%; SPF 50 sunscreens filter about 98%, and SPF 100 filter about 99%. No sunscreen protects you completely. The FDA requires any sunscreen with an SPF below 15 to carry a warning that it only protects against sunburn, not skin cancer or skin aging.
- “Water resistant” does not mean “waterproof.”No sunscreens are waterproof or “sweatproof,” and manufacturers are not allowed to claim that they are. If a product’s front label makes claims of being water resistant, it must specify whether it lasts for 40 minutes or 80 minutes while swimming or sweating. For best results, reapply sunscreen at least every 2 hours and even more often if you are swimming or sweating. Sunscreen usually rubs off when you towel yourself dry, so you will need to put more on.
