WHY IS WATER NECESSARY TO US?
The human body is to a great extent composed of water, as much as 70%. Water enters into the composition of intracellular and intercellular fluids-blood, lymph, gastric and intestinal juices, cerebral fluid, fluids of eyes, ears and joints.
The exchange of water is constantly going on. Water is forced through the sweat, evaporates through the skin and lungs and is excreted through urinary tract and colon. An average of 3.5 liters of water is drained away daily from the human body.
Naturally, these losses have to be compensated. The necessity for the use of water is the rule of life that we must not disturb.
No life process can take place without water. Cells that lose fluids simply die and cease to live. The body needs more than 5l blood to live. This amount and composition of essential blood could not sustain without water. Lungs can not breathe if their surface is not wet.
Food should not be taken without water. Water makes 90% of saliva and gastric juice.
Food is broken down by means of water and soluble waste is also removed by means of water.
The blood plasma is composed of 80% water and thus provides an environment for the bio chemical processes. Water transmits electrical impulses between cells to the muscles enabling them to move, eyes to see, brain to think …
Water regulates body temperature – cools the body by moisture or sweat that evaporates through the skin.
Finally, water lubricates the moving parts of the human body.
For all these reasons, it is clear that keeping balance of fluids is of crucial importance for the body.
