The sun provides light and heat, but it also sends out UV radiation. While we need some sun to help our bodies make vitamin D, too much of it can be very dangerous. UV radiation is a type of energy that comes through the atmosphere. It can cause serious damage to your skin and your eyes. When your skin gets too much sun, it can hurt your DNA. This damage often leads to problems like skin cancer or deep wrinkles later in life.
It is important to understand the UV index. This is a scale that tells us how strong the radiation is each day. Near the equator, the sun is usually much stronger. However, you must be careful everywhere. Even on cloudy days, UV rays can pass through the clouds and reach your skin. High levels of radiation can also hurt your immune system and cause eye damage, such as cataracts.
To protect yourself, you should follow a few simple steps. First, always look for shade when the sun is at its highest point in the sky. You should wear a hat with a wide edge and clothes that cover your arms and legs. Sunglasses are also necessary to prevent eye damage.
Using sunscreen is one of the best ways to stay safe. You should choose a bottle with a high SPF, such as thirty or fifty. This number shows how well the cream protects you from the sun. You must apply it to your skin twenty minutes before you go outside. Remember to apply it again every two hours, especially if you are swimming. Your skin is your body's natural protection, so you must take care of it every day. By following these rules, you can enjoy the outdoors without hurting your long-term health.
