How much water should you drink per day depending on your age?

Water is a basic nutrient for our body that must be drunk every day otherwise health suffers: "Water makes up 70% of body weight. Considered a kind of liquid gold for the body, it practically allows all our vital functions, even the exchange of oxygen from the air to the lungs can only work by passing through a veil", explains Dr. Ventura.

Given its importance, it is necessary to ensure the right amount, which is basically measured by 8-10 glasses a day, considering that one glass contains between 125 and 150 ml of water. Added to this are the personal factors that must be taken into account when drinking water, especially age.

For example, one liter of water per day is sufficient for children from 1 to 3 years of age, reaching one and a half liters to a maximum of 1.7 liters per day from the age of 9 to 13 years. To then reach two liters a day in adulthood. Of course, as the expert also specifies, the intake of water is dedicated both to drinking and present in fruits and vegetables.

The situation changes around the age of 25: "Over the years, the skin sees that these functions decrease and therefore the reserve of elastic substances and water decreases. Consequently, the epidermis loses its thickness and tone if we do not introduce an amount of fluids that allows us to compensate for this slowdown in cellular metabolism. Hence the concept that the more time passes, the more attention we should pay to proper fluid intake.

First of all, water helps to detoxify the body by eliminating a number of waste substances from the body, promoting diuresis and consequently the elimination of waste. They also improve cellular metabolic exchanges, facilitate intestinal transit, improve the appearance of the skin.

"This mechanism is effective because, contrary to what is thought, the intake of liquids in the right amount gives the body positive information about the abundance of water, a basic element and therefore for the fact that it should not be saved but eliminated".

The basic principle is that the body saves on those elements that are lacking and instead activates a positive metabolism on those that are present in abundance, therefore during a diet it is essential that the metabolism is always kept active in order to eliminate fat Excessive.

But if you drink too much water, what happens? Hyponatremia appears. This is overhydration that causes sodium levels to drop which then causes too much water to move into the cells and can lead to lung congestion and muscle cell loss. This is why it is essential to keep the level around two liters a day.
