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.
So drink up 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 dehydration when it's hot or you're sweating a lot with exercise. 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, fill it up, and drink up! If you're out in the hot sun or you're exercising on a hot day, it's easy to get heat exhaustion. Kids get heat exhaustion when their bodies can't cool themselves fast enough.
A kid with heat exhaustion might feel overheated, tired, and weak. Heat exhaustion can come on suddenly. A person may just collapse when playing soccer or tennis, for example. It can leave someone feeling really tired after it happens. Heat stroke is a more serious heat-related illness and can cause someone to stop sweating; to have red, hot skin; and to have a high temperature. The person might become uncoordinated, confused, or even lose consciousness.
It requires emergency medical attention. Be sure to tell an adult if you're hot and you have a headache or feel dizzy or nauseated like you're going to throw up.
The grown-up will want to get you out of the sun, give you liquids to drink, and take you to a doctor, if necessary. The good news is that the sun doesn't have to be your enemy if you wear your sunscreen, drink your water, and take breaks when you start to feel too hot. And don't forget your sunglasses. Not only do they protect your eyes from the sun, they make you look so cool! Note: All information is for educational purposes only.
