You've probably heard you need to drink plenty of water every day, but you may have wondered why. In a nutshell, your body needs water to function, and when you’re dehydrated, your heart has to work harder and faster to pump blood. Water also helps your muscles contract, lubricates your joints, and makes it easier for your brain to process information.
If you've been drinking less water than your body needs, once you start drinking enough, you’ll likely notice a change in how you feel. You may have more energy, feel more clear-headed, and exercise might even seem easier.
Still not motivated to up your H2O intake? Water can help you maintain a healthy weight. People who drink more water tend to consume fewer calories and less fat, sugar, and salt, according to a study published in the Journal of Human Nutrition and Dietetics.
