The roles of water - Water irrigates the whole body, constantly feeds the 50 billion cells that compose it, and allows the chemical exchanges that occur permanently within the organism. It is therefore found everywhere: in the blood and organs of course, but also in the cartilage, fat mass, muscles, teeth ...

- It serves to maintain the body at a constant internal temperature. When body temperature tends to increase because it is hot, feverish or engaging in heavy physical exertion, water evacuates heat through perspiration.

- It allows the elimination of the waste and toxins that encumber the organism. Filtered by the kidneys, the blood abandons some of the elements that pollute it. These residues are then diluted in water which flows dropwise into the bladder before being discharged from the body in the form of urine.

> The risks of dehydration

Being dehydrated means falling below 60% of water in the body. Any dehydration is detrimental to the organism, and is expressed differently according to its degree: from 1 to 2% dehydration, the performance (physical and intellectual) is already beginning to decrease; From 2 to 4%, they decrease by 3 to 20%; Of 4 to 6%, they decrease by 20 to 30%, difficulties of concentration and headaches can appear; 6 to 8%, performance may decrease by more than 30%, extremities peck and numb; To 10%, the functioning of organs is threatened; In excess of 15% dehydration, the vital prognosis is at stake.

The body can not be deprived of water for more than 2 or 3 days if one maintains normal activity and 5 days if one stays still.

> Needs and Advice

To maintain good water balance, the principle is simple: the volume of water coming out of the body must be compensated by the same volume of water entering. Of the 40 to 50 liters that the body contains, it loses every day between 2.5 and 3 by means of perspiration, urine, stool ...
It is therefore necessary to supply the same quantity daily, in the form of pure water of course (between 1 and 1.5 liters on average), but also of foods containing it (fruits and vegetables in particular).

Knowing that water losses vary considerably depending on temperature, humidity (ambient air content), altitude, physical activity, basic metabolism and hormones, Must be adjusted.

Drink regularly, throughout the day, and especially never to wait to be thirsty. This sensation, a real warning signal for the organism only appears late, when the body has already lost 1% of its weight in water.

To hydrate well, there is nothing like water that brings no calories, unlike sodas and other fruit juices full of sugar. In France, tap water undergoes many quality controls: there is no reason to sulk.
