The sunshine gives us vitamin D. This is good for our bones. But if you're going to be out in the sun, especially on a hot day, you need to stay safe. 

Always wear sunscreen.

Some people can get sunburns in the sun. Sunburns increase your chance of getting wrinkly when you get older. And worst of all, they can lead to skin cancer when you are an adult. So put on sunscreen 15 to 20 minutes before going out in the sun. Reapply sunscreen at least every 2 hours. Be sure to put sunscreen all over your body. This includes some places you might not think of, like the tops of your ears, the back of your neck, the part in your hair, your face, and the tops of your feet. You may need some help reaching the back of your body. So ask your parents or friends to give you a hand. If you want to block the sun's rays, wear a baseball cap or other fun hat to block your face from the sun. Your eyes need protection, too. So always wear sunglasses in the bright sun. 

Drink Water!

Drinking water is also important on a hot day. So drink water and don't wait until you're thirsty — drinking before you feel thirsty helps keep the water level in your body from dropping too low.  If you forget and suddenly feel thirsty, start drinking then. There are lots of cool-looking water bottles around, so get one you really like, and drink up!
