Water is great medicine, needed to maintain a healthy body, a clear mind and a good balance within your tissues. There's more water in your body than anything else, with every cell containing mostly water. About 60 percent of your body is water, and you must constantly replenish the supply, as it's used up in the processes of life.
Many people fail to drink enough of it.
When you don't have enough water in your body, your cells start to draw water from the bloodstream. The blood gets sludgy, your heart has to work harder, and your body starts to redirect blood away from less vital areas. Dehydration can set in even before you start to feel thirsty. This is a great strain on the body because it impairs the kidneys in their vital function of purifying the blood and helping the body get rid of toxins. If you've lost just 2 percent of your body weight in water, your brainpower and performance level may start to weaken.
