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.
Electrolytes are essential minerals in your body that are necessary for nerve and muscle function, the body-fluid balance, and other critical processes. They are particles that can carry an electrical charge and are present in your blood, plasma, urine, and other fluids.omiting and diarrhea are other causes of electrolyte imbalances, as they result in excessive fluid loss. You must replenish these fluids and electrolytes in order to prevent dehydration, a potentially life-threatening condition.
