Water
The human body is composed of 70% water. The human body cannot survive without water. Dehydration and death can occur within 5 days without water. Even a slight drop in body water can trigger many physical and mental health problems.
Water is involved in ever bodily function. It is required to carry nutrients through the body; Maintain body temperature and then carry waste and toxic materials out of the body. It is required for chemical reactions that occur in the body and are necessary for human life. Since our body is constantly using water to survive, it is important to continually replace the water used by the body. It is suggested that 6-10 glasses of water be consumed each day.
