Learn how much water kids need each day, why hydration supports learning and physical activity, and simple ways parents and teachers can help kids stay hydrated.
Why Hydration is Essential for Kids’ Health and Learning
Water plays a critical role in a child’s physical health, emotional regulation, and ability to focus. Kids lose water throughout the day through sweating, breathing, and normal bodily functions, especially when they’re active at school, recess, PE, or run clubs
Proper hydration helps children:
- Regulate body temperature
- Transport nutrients and oxygen
- Remove waste from the body
- Support joint and muscle health
- Improve focus, mood, and learning readiness.
When kids don’t drink enough water, even mild dehydration can lead to fatigue, irritability, headaches, and difficulty concentrating – all things educators and parents work hard to avoid.
How Much Water Should Kids Drink Each Day?
While individual needs vary, general daily hydration guidelines for children include:
- Ages 4 to 8 years old: 4 – 5 cups
- Ages 9 to 13 years old: 5 to 7 cups
- Ages 14 to 18 years old: 6 to 8 cups
💡 Important reminder: Kids need water year-round, not just during hot weather. Hydration is just as important in winter, even when thirst cues may be lower.
During warmer months – or when kids are participating in physical activity like PE, recess, Mileage Club, or sports – water needs increase. Encourage drinking before, during, and after activity, even if kids don’t feel thirsty.
Hydration & Physical Activity Go Hand in Hand
Active kids sweat more and lose fluids faster. Without adequate hydration, performance and enjoyment suffer. Drinking water regularly helps kids:
- Stay energized
- Recover more quickly
- Avoid heat-related illness
- Enjoy movement-based programs like run clubs and brain breaks
11 Easy & Fun Ways to Encourage Kids to Drink More Water
- Offer water in colorful cups or with silly, curly straws.
- Turn a plain reusable water bottle into a DIY with your kid.
- Add some flavor – freeze citrus slices, strawberries, or watermelon chunks.
- Make homemade infused water – add cucumber slices and even herbs like mint or basil.
- Encourage eating water-rich fruit and vegetables – tomato, cucumber, carrots, watermelon, cucumber slices, zucchini, zucchini noodles, strawberries, pineapple, oranges, and kiwi.
- Freeze small batches of sliced fruit for an on-the-go refreshing snack.
- Fruit popsicles.
- Avoid sugary drinks like soda/pop or juice.
- Make sure they always pack a water bottle.
- Mark lines on the water bottle – create a goal and encourage your kid to drink a certain amount of water throughout the day.
- Encourage drinking water before, during, and after activities to make up for sweat loss, especially during the summer. Be a good example and drink water with them – create a game or little competitions throughout the day to drink water.
