Sunscreens also come in many forms and are widely available. There are some common myths that keep us from applying sunscreen every day. The first is that some of us think we don't need sunscreen when it's cold or cloudy outside. This misconception is simply false. The sun's ultraviolet radiation reaches the Earth at about 40% on completely cloudy days, even if it is cold outside. Wearing clothing that protects your exposed skin is another way to prevent skin cancer. Light cotton clothing that is not black in color can be worn for protection. It's so simple and potentially fashionable with a wide-brimmed hat and cute sunglasses that can absorb ninety-nine or one hundred percent of ultraviolet rays. It's also easy to seek shade outside. Another way is to closely examine the skin on your body daily, know your skin, and pay close attention to anything abnormal in size, color, or shape. Keep an eye out for any spots that look suspicious or won't heal. It only takes a few minutes and can be incorporated into your daily shower routine. For skin that you can't easily see, like that on your back, you can ask a friend or loved one to take a look and report anything that looks suspicious. It is also possible to visit a dermatologist once a year and get a visual exam.
