Functions of Water in the Body
The functions of water in human body are vital. Every system in human body depends on water to function.
- Water is essential to body's temperature regulation, keeping it cool through perspiration.
- Water flushes out toxins and wastes. Adequate water intake enables our body to excrete waste through perspiration, urination, and defecation. The kidneys and liver use it to help flush out waste, as do our intestines.
- Water is a major component of blood which carries nutrients and oxygen to and from all cells.
- Water provides a moist environment for all body tissues. It is the major component of saliva and mucous which lubricates the membranes that line our digestive system beginning with the mouth. Mucous membranes in the nose and eyes function better when well hydrated.
- Water forms the fluids that surround the joints.
- Water cushions joints and protects tissues and organs like the brain from shock and damage.
- Water helps maintain a healthy weight.
- Moisturizes the air in lungs

What will happen if water is less in our body?
Water consumption keeps the body hydrated. Lack of water can lead to dehydration, a condition that occurs when we don't have enough water in our body to carry on normal functions. Even mild dehydration - as little as a 1 percent to 2 percent loss of our body weight - can sap our energy and make us tired. Dehydration poses a particular health risk for the very young and the very old. Signs and symptoms of dehydration include:
- Excessive thirst
- Dry mouth
- Little or no urination
- Muscle weakness
- Light headedness
