How much water should you drink per day? Here is the truth. “Mad”

Why is water so important that it is drunk all the time, every day and in large quantities? The answer, indeed, the answers are quite simple:

– Water promotes the elimination of waste that is in our body because it increases the excretion of urine and sweat.
-It promotes the muscle development of all those who practice physical activity because 75% of our muscle mass is made up of water and opposes the catabolic effects of cortisol.
-It has an “aesthetic” effect because it gives shape and rigidity to fabrics.
-Helps keep the surfaces of the nose, eyes and ears well moistened.
– Promotes adequate joint lubrication through the production of synovial fluid. Is drinking lots of water useful for “losing weight”? No, quite the contrary and we will explain to you right away why: excessive water consumption (for example 4 or 5 liters of water per day, in the total absence of physical activity or particular climatic conditions) does not that slow down digestion.

Drinking too much during meals also leads to excessive dilution of gastric juice so that, as a result, the meal tends to “stay in the stomach”. So what is the right amount of water to drink each day? We can say that the ideal quantity is between 1200 ml (so 6 glasses of water) and 2000 ml (10 glasses of water). The average consumption of 1500 – 1600 ml can also be obtained by consuming in a precise and very simple way: drink a glass of water at breakfast, two at lunch, two at dinner and half a liter during the day outside meal.

However, water consumption should be increased in the following cases:
– If a physical activity is practiced: it generates heat and to avoid an excessive rise in body temperature, the body increases the sweat which, by evaporating, evacuates the heat from the heated body.
– At high altitude: at altitudes above 2500 meters, the excretion of urine but also the respiratory rate increase an increase in water loss by our body (water vapor is contained in the water that is exhaled and , normally, every day, between 250 ml and 350 ml of water are eliminated by this route).

However, on all occasions when there is an increase in perspiration, as well as physical activity such as feverish states or particularly hot climates or in the event of water loss due to diarrhea or vomiting but also in cases of pregnancy and lactation, cases in which a daily water intake of 2100 ml per day and 3100 ml per day is indicated respectively.
