Your body needs water every day to work properly. Water helps carry nutrients around your body, keeps you cool when you are hot, and helps get rid of waste. More than half of your body is made of water.
Track water intake during the day with a simple chart. Compare how you feel after playing outside with water versus without. Observe how plants wilt without water as an analogy for why bodies need water too.
Children sometimes think juice and soda count the same as water. Others think you only need to drink when you feel thirsty, not realizing that thirst means your body already needs water.
Water might seem plain compared to juice or soda, but it is the most important drink for your body. More than half of your body is actually made of water — it is in your blood, your muscles, your brain, and even your bones. Every single part of you needs water to do its job.
Water works like a delivery truck inside your body. When you eat food, your body breaks it down into tiny helpful pieces called nutrients. Water carries those nutrients through your blood to every part of your body that needs them. Water also helps your body get rid of things it does not need anymore — that is one reason you go to the bathroom. And when you run around and get hot, water helps cool you down by making sweat, which dries on your skin and takes heat with it.
When your body does not get enough water, it starts to slow down. You might feel tired, get a headache, or find it hard to think clearly. That is why it is smart to drink water throughout the day — not just when you feel thirsty. Thirst is your body's late warning signal, like a fuel light in a car that comes on when the tank is already getting low. Keeping a water bottle handy and taking sips during the day keeps your body running smoothly.
