Water: Why We Need It. Hydration is important because the body is comprised mostly of water, and the proper balance between water and electrolytes in our bodies really determines how most of our systems function, including nerves and muscles, says Larry Kenney, PhD, a professor of physiology and kinesiology at Penn State.
