Modern nutritionists recommend adhering to the basic rule of nutrition and a he althy lifestyle - drink 2 liters of water a day. This is how many glasses you need to drink, you will be surprised? Where did such a norm come from and is it necessary to observe it to the fullest extent, reproaching yourself for every unfinished glass?

2 liters of water is how many glasses?

First, let's answer the main question: 2 liters of water is 8 glasses. The calculation is an ordinary faceted glass, filled to the brim. In dietetics, this rate of water consumption is called the “rule of 8 glasses”, but no one knows for sure the root cause of its appearance.

Where did the "8 cups rule" come from?

Once the question "2 liters of water is how many glasses?" interested an eminent neurologist from the United States named Heinz V altin. He was interested in this norm, and he decided to conduct a series of studies confirming the "rule of 8 glasses".

He concluded that this recommendation was the result of a scientific misunderstanding. Back in the years of World War II, the department of the US government responsible fordietary norms, recommended to use water for the assimilation of kilocalories. The calculation was made as follows: the daily norm of kilocalories is about 1900 kcal, for each kilocalorie there should be at least 1 ml of water, in total we get almost 2 liters every day.

But then, many factors were not taken into account, which ultimately should make adjustments to the rate of water consumption.

To each his own norm

It turns out that the norm can be strictly individual and depend on the following points:

• Climatic conditions - when the weather is too hot, the body gets rid of more fluid in the form of sweat.
• Food and Drinks – Half your daily hydration can come from food, while tea or coffee is a diuretic and dehydrates you.
• Lifestyle - when playing sports or heavy physical exertion, the body loses more moisture. It is also known that the body of a nursing mother loses 1.5 times more water and calories per day than the body of an ordinary person.

The glass rule is starting to melt by the day today as it's pretty clear that a frail office girl needs less water than an athlete or loader. Can a baby drink at least one glass?

How to understand that there is not enough water?

In 2004, the same department admitted its old mistake and published new data - a person is recommended to drink much more daily.more than 2 liters of water. How many glasses do you need to drink, you ask? Doesn't matter at all!

Not a single unfinished glass affects anything at all, you need to drink as much water as you want. There are studies that prove that a he althy person effortlessly consumes the amount of fluid they need along with food and drinks. Therefore, it is absolutely not necessary to know how much water is in a glass. It is only recommended not to forget to replenish moisture reserves in hot weather and during power loads in order to prevent dehydration. And it's best to just drink when you feel like it.
