The flow of water inside and outside the cells generates energy. This energy is stored in the body along with other chemical sources. The energy generated by the water in the cells helps transmit impulses in the nerves. It transports the chemical substances produced by the brain that carry its messages to different parts of the body. Water content in the body influences the functions of the various proteins and enzymes that are dissolved in it.
Water helps maintain the moisture of the lining of the internal organs of the body.
It maintains normal volume and consistency of fluids such as blood and lymph. It regulates body temperature. Water is essential for regulating the normal structure and functions of the skin. The body loses about four liters of water every day. It is therefore necessary to replenish this volume by drinking at least the equivalent amount of water every day.
