WATER, A VITAL ELEMENT

 

Water is the main constituent of the human body. The amount of water in the body varies throughout life.

 

- It decreases with age due to the loss of muscle mass. Thus, the body water weight of a newborn is 74% and it decreases to 50% for a man and to 47% for a woman from the age of 50. The average amount of water contained in an adult body is 65%, which corresponds to about 45 liters of water for a 70 kg athlete.

- Men have a higher body weight in water than women because of a generally lower average fat mass.
