Drinking water is an important part of staying healthy, especially when it's hot outside.
When you're sweating , you lose water that your body needs to work properly. And if you're playing a sport or running around in the sun, you lose even more water, because you sweat that much more. Don't wait until you're thirsty - drinking before you feel thirsty replaces the water your body needs. If you forget and suddenly feel thirsty, start drinking then. If the sun is very hot one day and you're running around a lot, it can sometimes cause heat exhaustion .
