You are skateboarding down the path. It is a hot summer day. It looks like you have been swimming. But you haven’t. You are just soaking wet with sweat!
You have about two million sweat glands all over you body. These sweat glands have tiny tubes that bring sweat from within you skin to the surface of your body. Why? It helps rid your body of heat.
When you exercise really hard, your body temperature rises. It’s important to get rid of that extra heat. So your body has a built-in cooling system. How does it work? Well, as the water in sweat evaporates or drips off of you, it carries heat away from your body. This helps you to stay cool.
It’s important to drink enough water every day to keep your cooling system working well, which is easy to do when you are thirsty. In fact, you may be gulping down a large, cool drink.
