Water and its role in human life

Water is the main component of any living organism including people. Nobody will be able to exist without water. It makes about 70percent of the human body and higher than 90percent of some vegetables. Water is capable of regulating all vital processes. It:

- normalizes humidity of oxygen increasing its absorbability;

- carries out thermal control of the body;

- dissolves nutrients helping an organism with their assimilation;

- humidifies and creates protection to vitals;

- forms protective lubricant for joints;

- improves exchange processes in activity of systems of an organism;

 - discharges various waste out of an organism.

Long-term blood tests under a microscope proved that the reason of the majority of modern diseases is in dehydration of an organism and the subsequent acidulation of blood. It is impossible to allow organism dehydration. Disturbing symptoms of this trouble are the dry skin accompanied with itching, fatigue, sharp decrease in concentration of attention, arterial blood pressure, headaches and general malaise. By scientific research it has been proved that the daily use of enough clear water helps to struggle with serious illnesses. It promotes easing of pains in the back and displays of migraine. Also it helps to decrease blood pressure and the level of sugar and cholesterol in the blood.
