Water is very important. We can live more than two weeks without food. However, we can only live for eight to ten days without water. Water goes around our body through blood. It carries oxygen and food for cells. It clean our body and brings the waste in sweat and urine. It also keeps the balance of minerals in our body. Most parts of human body use water to work. We cannot move well if there is not enough water in our body.
Sixty five percent of our body is water. To keep that amount of water in our body we must drink an overage of eight to ten galasses of water each day. How much water does a person need everyday? It depends on the volume of urine, and sweat. An athlete who does alot of physical exercise certainly needs to drink more water. Beside drinking, many kinds of food are also a good source of water. Fruit and vegetable, for instance, is eighty to ninety five percent water.
