Water being the largest constituent of the body makes up  55 – 60% of the body weight. It is a primary constituent of all body fluids and acts as a universal vehicle for transporting all chemicals within the body.


  • Water is essential for the process of digestion and absorption.
  • It acts as a medium of excretion of body waste in the form of urine.
  • Water acts as a structural component and imparts form to cells.
  • It acts as a transport medium for nutrients.
  • It regulates the internal body temperature by distributing the heat in the body.
  • Water intake also affects bowel movement and thus prevents constipation.

To maintain health, water needs to be replaced every 24 hours as it is not stored in the body. Water loss occurs through the kidneys in the form of urine. About half liter of water is lost as water vapor in breath. Another half liter or more, depending upon the outside temperature and humidity is lost from the skin as visible or invisible perspiration in order to maintain a soft healthy skin and regulate internal body temperature.

The proper volume of water or liquid to be consumed per day should be enough to produce 1-1.5lt. of urine in order to keep the blood clean. Taking all this into account, the body needs approximately 2.5 liter of water. However, do recall that food contributes quite a bit of water. Hence, not all this amount needs be taken as water or in the form of beverages.

Therefore, have at least 8 – 10 glasses of water in a day for efficient functioning of the body.
