Almost 60 percent of the human body is water, which is little wonder when you find out why this fluid is so vital to your body's function. Each day, the body must replace 2.4 liters of water, mostly through drinking water and consuming foods with a high water content.

Water helps keep the body cool when exposed to intense temperatures. The sweat produced during a workout is one good example of why drinking water is so vital.

The human brain is composed of about 70 percent water. Water protects the brain and spinal cord as it acts as a shock absorber, according to the U.S. Geological Survey website. Drinking water is necessary to ensure that they are properly cushioned.

Your joints also rely on the fluid that surrounds them for cushioning and to keep them moving freely. Not drinking enough water can cause your joints to feel stiff.

Water is necessary to move wastes through the body. Whether through urine or bowel material, water is used by the excretory organs to eliminate wastes. Not drinking enough water can cause a person to experience diarrhea or vomiting symptoms related to dehydration.

Drinking water also benefits the skin. If your skin is not getting the sufficient water, it will become dry, tight and flaky. Dry skin is prone to wrinkling.
