Why do we need to drink enough waters

A person of average size spends more than 2 liters of body water per day. In fact, the body loses more than one liter per day of body water through the urine, and the same amount through sweat, stool and breathing (as revealed by the mist on a mirror placed near the mouth ).

To maintain the blood volume and the volume of saliva

Our cells and organs, mainly the brain and muscles, need oxygen to absorb the nutrients they need, so they can produce the energy they need to function. They absorb oxygen and release CO2. An infinite cycle. And it's the blood that gives them the oxygen they need. This is why significant blood loss can have irreversible and even fatal consequences. The blood is composed of 55% plasma, itself composed of 90% water.

saliva plays a vital role in the digestive process by transforming food so that it is more easily absorbed by the body. It is therefore greatly involved in the assimilation of nutrients essential to the proper functioning of the body. Saliva is 90% water.

To regulate body temperature and renew urine and sweat

The internal temperature can reach up to 37.8 ° C without danger. After that, the body triggers its thermal regulation mechanism, especially through perspiration. The evaporated water allows the body to cool down and the temperature to drop. The hotter the body, in full sun or during a physical activity for example, the more it will sweat. It is therefore even more essential to think about rehydrating in these conditions.

if sweat plays a major role in the thermal regulation, it also participates, with the urine, in the elimination of metabolic and toxic wastes, such as the food not absorbed by the body or the medicinal residues. Urine also helps maintain balance between the various minerals present in the body. Urine is 95% water.
