Water makes up more than two-thirds of the weight of the human body. Without water, humans would die in a few days. All the cells and organs need water to function.

Water serves as a lubricant and is the basis of saliva and the fluids surrounding the joints. Water regulates the body temperature through perspiration. It also helps prevent and alleviate constipation by moving food through the intestinal tract.
