Water Basics

Water is one of the most essential components of the human body. Water regulates the body’s temperature, cushions and protects vital organs, and aids the digestive system. Water not only composes 75 percent of all muscle tissue and about 10 percent of fatty tissue, it also acts within each cell to transport nutrients and dispel waste. And, because water composes more than half of the human body, it is impossible to sustain life for more than a week without it.
