Now that Summer has officially arrived, it is important to remember that skin cancer is the most common type of cancer in the United States and is mainly caused by the ultraviolet (UV) rays from the sun. The American Academy of Ophthalmology recognizes July as UV Safety Month to help raise awareness about skin cancer and help people take action with prevention. A few simple, everyday steps can be taken to help prevent you from overexposure and the harmful effects of UV radiation. Below are simple, everyday steps you can take to safeguard your skin from the harmful effects of UV radiation from the sun.
– Wear proper clothing - Wearing clothing that will protect your skin from the harmful ultraviolet (UV) rays is very important. Protective clothing are long-sleeved shirts and pants are good examples. Also, remember to protect your head and eyes with a hat and UV-resistant sunglasses. You can fall victim to sun damage on a cloudy day as well as in the winter, so dress accordingly all year round.
– Avoid the burn - Sunburns significantly increase one's lifetime risk of developing skin cancer. It is especially important that children be kept from sunburns as well.
– Go for the shade - Stay out of the sun, if possible, between the peak burning hours, which, according to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), are between 10 a.m. and 4 p.m. You can head for the shade, or make your own shade with protective clothing - including a broad-brimmed hat, for example.
– Use extra caution when near reflective surfaces, like water, snow, and sand - Water, snow, sand, even the windows of a building can reflect the damaging rays of the sun. That can increase your chance of sunburn, even if you’re in what you consider a shady spot.
– Use extra caution when at higher altitudes - You can experience more UV exposure at higher altitudes, because there is less atmosphere to absorb UV radiation.
– Apply broad-spectrum sunscreen - Generously apply broad-spectrum sunscreen to cover all exposed skin. The “broad spectrum” variety protects against overexposure to ultraviolet A (UVA) and ultraviolet B (UVB) rays. The FDA recommends using sunscreens that are not only broad spectrum, but that also have a sun protection factor (SPF) value of at least 15 for protection against sun-induced skin problems.
– Re-apply broad-spectrum sunscreen throughout the day - Even if a sunscreen is labeled as "water-resistant," it must be reapplied throughout the day, especially after sweating or swimming. To be safe, apply sunscreen at a rate of one ounce every two hours. Depending on how much of the body needs coverage, a full-day (six-hour) outing could require one whole tube of sunscreen.
