Water is the major component of your blood. About 70% of your total weight is water. Your body uses water for cleansing and cooling itself, and to maintain a proper chemical balance. You lose water when you perspire, when you breathe and through body waste. A loss of 20% of your body’s water could even prove fatal.

Forcing the body to work with limited amounts of fluid is like trying to wash the dinner dishes in a cupful of water. We should drink enough water to keep the urine pale. Usually that would mean about 8 cups a day.
