Without water, life would not exist. Imagine: the human body is 60% composed! Explanations and advice on the best friend of our form and our beauty: water.

> The roles of water - Water irrigates the entire body, continuously supplies the 50 billion cells that make it up, and allows the chemical exchanges that occur permanently within the body. It is found everywhere: in the blood and organs of course, but also in cartilage, fat, muscles, teeth ...

- It serves to maintain the body at a constant internal temperature. When body temperature tends to increase because of hot weather, fever, or heavy physical exertion, water expels heat through perspiration.

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

> The risks of dehydration

To be dehydrated is to go below 60% of water in the body. Any dehydration is harmful for the body, and is expressed differently depending on its degree: 1 to 2% dehydration, performance (physical and intellectual) are already starting to decline; from 2 to 4%, they fall from 3 to 20%; from 4 to 6%, they decrease by 20 to 30%, difficulties of concentration and headaches can appear; from 6 to 8%, the performances can decrease by more than 30%, the extremities tingle and become numb; at 10%, the functioning of the organs is threatened; beyond 15% of dehydration, the vital prognosis is at stake.

The body can not be deprived of water for more than 2 or 3 days if we keep a normal activity and 5 days if we stay still.

> Needs and advice

To maintain a good water balance, the principle is simple: the volume of water coming out of the body must be offset by the same volume of water that enters. Of the 40 to 50 liters that the body contains, it loses every day between 2.5 and 3 through perspiration, urine, stool ...

It is therefore necessary daily to bring him the same quantity, in the form of pure water of course (between 1 and 1.5 liter on average), but also of foods which contain it (fruits and vegetables in particular).

Knowing that the water losses vary considerably depending on the temperature, the hygrometry (moisture content of the ambient air), the altitude, the physical activity or the basic metabolism and the hormones, it must adjust its contributions.

It is necessary to drink regularly, throughout the day, and especially never to wait to be thirsty. This sensation, a real alarm signal of the body only appears late, when the body has already lost 1% of its weight in water.
