You need water to digest your food and get rid of waste, too. Water is needed for digestive juices, urine (pee), and poop. And you can bet that water is the main ingredient in perspiration, also called sweat. Besides being an important part of the fluids in your body, water is needed by each cell to function normally. Your body doesn't get water only from drinking water. Any fluid you drink will contain water, but water and milk are the best choices. Lots of foods contain water, too.
Importance Of Drinking Water. You and I know that the human body is largely made up of water â we learnt that in school. And yet, most people simply do not drink enough water. Unfortunately, unlike other nutrients, water is not stored in the body. Therefore, it needs to be continuously replenished. The body loses water through sweat, urination, feces and even the air we breathe out. If you donât drink enough fluid you can get dehydrated and worse. Even a 5% drop in your body fluids will lead to 25-30% loss of energy. You can also suffer from bad breath, your digestion is impaired and your brain wonât function properly. You can suffer from headaches, irritability, heartburn and even body ache.
