Ultraviolet radiation is a major cause of skin cancer. There are two kinds of ultraviolet rays: ultraviolet A (UVA), which can penetrate glass. The study shows that UVA rays causes premature aging and wrinkling of the skin. It also plays a role in causing basal cell carcinoma, squamous cell carcinoma and melanoma. Although ultraviolet B (UVB) cannot pass through car windows and other types of glass, it is more closely associated with the development of skin cancer and melanoma. And it will make you burn. So it’s important to protect your skin from UVA and UVB radiation.
Sun damage will not appear in a short time, it will form in a long period of sun exposure. One of the easiest ways to prevent skin cancer is to apply sunscreen every day. However, most of us still forget to slather on the sunscreen. To protect your skin from the sun, make sure use the sunscreen every day, even on cloudy days. Apply one ounce of sunscreen at least 15 to 30 minutes before going outside. Use the sunscreen with an SPF of at least 30.
Choose a broad-spectrum sunscreen that protects against both UVA and UVB radiation. Make sure it’s waterproof and has an SPF of 30 or higher. Other sunscreens may help you avoid sunburn, but they don’t prevent you from getting skin cancer. Reapply sunscreen every two hours. If you’re swimming or sweating, reapply it every hour. These surfaces of water and sand reflect the sun’s harmful rays, which can increase your chance of getting sunburned.
If possible, you can wear long-sleeved shirts and long pants to cover your body. Dark clothing and tightly woven fabrics block the sun better than white or loose fabrics. To get extra protection, look for clothes made with special sun-protective materials. Wear a sun hat that will protect your face, neck, ears, matching with a pair of sunglasses to protect your eyes. Sun hats come with many kinds of designs and colors, which provide different level of sun protection. Such as bucket hats, fedora hats, straw hats, wide-brimmed hats and more. These sun hats all have ability in blocking the sun and its harmful rays out of your skin. A bucket hat is one of the most popular hats among many people. It features a floppy brim and deep crown which offer you better protection than a baseball cap. Sunglasses with lenses can absorb 99% to 100% of UV rays, which will provide the best protection for your eyes and the surrounding skin.
The sun is the most intense between 10 a.m. and 4 p.m. You can see this from your shadow, if your shadow is shorter than you, you should protect yourself from the sun. Babies under 6 months old should stay in a completely cool place. The UV index measures how much damage is done by exposure to the sun on a particular day. It is often appear in the weather report. When the index reaches 10 or higher, people should try to stay indoors. Water, snow and sand reflect harmful UV rays of the sun, and increase the risk of getting sunburn.
