It’s a matter of quantity. We are often told that it is important to hydrate regularly. It’s true, our body is made up of 2/3 water, which provides many vital functions. And naturally, we burn, 2.5 liters a day. But it’s proven, if we lose more than 15% of our weight in water, we are in danger of death, but we are also if we drink too much!
We call that hyponatremia, an overhydration whose consequences can be terrible. There have already been deaths of runners who had drunk too much at once after marathons. Why ? Because in this case, nos reins no longer remove water fast enough and the mineral salts that our body needs are diluted.
The consequence is that this excess water seeps into the cells of the nervous system. And there our brain, like a sponge, begins to absorb it and can lead to the formation of a cerebral edema which can lead to coma and therefore death.
That is why reasonably it is better avoid going beyond 5 liters per day. 2 liters, spaced out, is more than enough, especially since the rest of our diet, fruits and vegetables in particular, already brings us a liter without us realizing it. Either way, if you drink too much, your body will send you signals: clear urine, headaches, nausea, swollen hands and discolored lips. Finally, water is like alcohol: with moderation !
