Find out all the information about human hydration you may need: from the importance and benefits of a healthy hydration and the consequences of dehydration, to the hydration needs according to age, special populations and special conditions, and the sources of water which contribute to fulfilling your needs.
Appropriate hydration of the body is an absolute requirement for health and is essential for life itself. Water sustains the body's many vital chemical reactions and maintains correct body functions.
Water plays many important roles within the body. Water is the major part of most of the body’s cells (except for fat cells) and it also cushions and lubricates the brain and the joints. It transports nutrients and carries waste away from the body cells. It also helps regulate body temperature by redistributing heat from active tissues to the skin and cooling the body through perspiration.
Dehydration is the loss of water from the body in excess of the amount consumed.
