Any healthy inactive adult residing in a temperate climate should maintain an intake of 1.5 liter of water per day. The consumption of water enables the body to remain hydrated and balance water losses. Water is a major constituent of a human body and vital organs. Water provides many vital functions in our body, namely in cell life, chemical and metabolic reactions, transport of nutrients, body temperature regulation and elimination of waste. Water is our bodyâs most essential and important nutrient. It is involved in every bodily function and constitute for 70-75% of human total body weight. The lack of water in the body in sufficient amount can make it stop working properly.
Water's unique chemical and physical properties are essential to human survival. Without water, basic physical processes would be impossible. Cells within the human body would die. None of the essential physical functions, such as breathing, digestion, or muscle movement could take place without water. About 70 percent of the human body is made up of water and, coincidentally, more than 70 percent of Earth is covered in water. Water creates an environment that sustains and nurtures plants, animals and humans, making Earth a perfect match for life in general.
