What Water Does in Your Body
Water plays a role in nearly every bodily function you can think of. It helps your digestive system break down food and absorb nutrients so your body can use them for energy. Water cushions and lubricates your joints, which is especially important when you are running, jumping, or playing sports. Your blood, which is mostly water, carries oxygen and nutrients to every cell in your body. Water also helps regulate your body temperature through sweat, keeping you cool during exercise or hot weather.
How Much Water Do You Need?
The amount of water you need depends on your age, size, and how active you are. Children ages 9 to 13 generally need about 5 to 8 cups, or roughly 1.2 to 2 liters, of water per day. During hot weather or intense physical activity, your body loses more water through sweat, so you need to drink even more to keep up. Fruits, vegetables, and soups also contain water that counts toward your daily intake. Paying attention to your body’s signals and drinking regularly throughout the day is more effective than trying to drink a large amount all at once.
How to Check Your Hydration
The easiest way to check whether you are drinking enough water is to look at the color of your urine. Pale yellow, like the color of lemonade, means you are well-hydrated and your body has enough water. Dark yellow or amber-colored urine is a sign that you need to drink more water soon. If your urine is completely clear, you may actually be drinking too much, which can dilute important minerals in your body. Other signs of dehydration include feeling thirsty, having a dry mouth, feeling tired, and getting headaches.
Thirst, Hunger, and Hydration
Many people confuse thirst with hunger because the signals can feel similar. When you think you are hungry between meals, try drinking a glass of water first and waiting a few minutes to see if the feeling goes away. This simple habit can prevent unnecessary snacking and help you stay properly hydrated at the same time. Dehydration can also affect your mood and ability to concentrate, so if you are feeling cranky or having trouble focusing at school, a drink of water might be exactly what you need. Keeping a water bottle nearby makes it easy to sip throughout the day.
Drinks That Help and Hurt
While water is the best choice for staying hydrated, other beverages can help or hurt your hydration levels. Milk, 100 percent fruit juice, and herbal teas all contribute to your daily water intake. However, caffeinated drinks like sodas and energy drinks can actually work against hydration because caffeine is a mild diuretic, which means it causes your body to lose water more quickly. Sugary drinks also add extra calories without providing the nutrients your body needs. Making water your go-to drink is the healthiest choice for keeping your body properly hydrated.
Building Hydration Habits
Like any healthy habit, staying hydrated gets easier when you build it into your daily routine. Carrying a reusable water bottle with you to school and activities serves as a constant reminder to drink. Setting small goals, like finishing one bottle by lunch and another by dinner, helps you track your progress. Drinking a glass of water with every meal is an easy habit to remember. Eating water-rich foods like watermelon, cucumbers, oranges, and strawberries adds to your hydration without any extra effort.
Staying hydrated has a direct impact on how well you perform in school and in sports. Even mild dehydration, losing just 1 to 2 percent of your body’s water, can reduce your ability to concentrate, slow your reaction time, and make physical activities feel harder. Athletes who drink water before, during, and after exercise perform better and recover faster than those who do not. Your brain is about 75 percent water, so keeping it hydrated helps you think more clearly, remember what you have learned, and stay in a positive mood throughout the day.
