The sun is very important for our health. It gives us light and warmth. It also helps our bodies make vitamin D. We need this vitamin to have strong bones. When we go outside in the sun, we often feel happy. However, we must be very careful because the sun can also hurt us.
Scientists say that the sun sends out UV light. We cannot see this light, but it can change our skin. If you stay in the sun for too long, your skin can get burned. This is painful and can be dangerous. Over a long time, too much UV light can cause skin cancer. It can also hurt your eyes.
Scientists use a special scale to measure how strong the UV light is. Sometimes the sun is very strong in hot places, like near the sea. But you can also get burned on cloudy days. Even if you do not feel the heat, the UV light is still there. People with dark skin have more protection, but they still need to stay safe.
There are many easy ways to protect yourself. First, you should use sun cream. You must put it on your skin twenty minutes before you go outside. Do not forget to put it on your face, ears, and neck. Second, you should wear a hat and dark glasses to protect your eyes. Third, try to stay in the shade when the sun is very strong in the middle of the day.
If you follow these simple rules, you can enjoy the sun without getting hurt. You will get the vitamin D you need for your bones and blood. Remember to use sun cream and wear your glasses every time you go out. Stay safe and have fun in the sun.
