About two-thirds of your body weight is water. All your cells need water to work. Water is also the base for all your different body fluids, including saliva, blood, urine, sweat, and joint fluid. No living thing can survive without water. How do you know if you’re drinking enough?
Your body loses water when you sweat, go to the bathroom, and even when you just breathe out. So, you need to drink enough water to replace what you lose. When you don’t drink enough water, you can become dehydrated.
