 About 50-70 percent of the human body is composed of water. The exact amount of bodily water varies according to age and the proportion of muscle-to-fat (muscle contains more water than fat.) Although water contains no calories and may have no nutrients, it is essential for life. We can survive for weeks without food, but only a matter of days without water. Because we do not store excess water, we must ensure that our daily diet contains a sufficient supply to maintain adequate health. It's extremely difficult to take in too much water. If we drink too much, our body simply adjusts by increasing the amount of liquid we urinate. However, if our water level inside our body falls too low, we experience several symptoms that warn us we may be dehydrating. The principal symptom is thirst, a reaction influenced by a group of nerve cells located in the hypothalamus, located at the base of the brain.
