Water is one of the most essential nutrients in the body and comprises of about 70% of the body’s weight. It plays a role in regulating body temperature, maintaining the body’s acid-base balance and taking part in every chemical reaction that occurs in the body.
Water is regulated in the body by a center in the brain that controls our thirst response. When the body needs water we become thirsty, when we have too much water in our body the brain sends a signal to the kidneys to get rid of water in the urine.
It is recommended that an adult should take six to eight glasses of water daily. When you are thirsty, only water can quench your thirst.
