What is the recommended amount of water to drink

It seems that the recommendation to drink 8 glasses of water a day, or about two liters, is not entirely correct, at least it is more than many people can stick to every day.

According to a new study, many people only need 1.5 to 1.8 liters a day, less than the normally recommended two liters.

“not scientifically supported”

Yosuke Yamada of the National Institute said to innovate Biomedical, Health and Nutrition in Japan, and one of the first authors of this research that “the current recommendation (i.e. drinking 8 cups) is not supported scientifically at all,” adding that “most scientists are not sure of the source of this recommendation.”

One of the problems, according to the British newspaper, is that previous estimates of human needs for water ignore that our food contains water, which can contribute a large proportion of our total consumption.

As Yamada explained, “If you only eat bread and eggs, you won't get much water from food. But if you eat meat, vegetables, fish, pasta and rice, you can get about 50% of your body's water needs.

Hot and humid climates

In addition, the study, published in the journal Science, assessed the water intake of 5 people between the ages of 604 days and 8 years from 96 countries.

But the study revealed that those who live in hot and humid climates and at high altitudes as well as athletes and pregnant and lactating women need to drink more water.

The recommended amount of water to drink daily

I also noticed that men between the ages of 20 and 35 had an average water “circulation” of 4.2 liters per day. This decreased with age to an average of 2.5 liters per day for men in their XNUMXs, which of course depends on the energy expended by the body.

As for women between the ages of 20 and 40, the rate of “circulation” of water in the body was 3.3 liters, and it decreased to 2.5 liters upon reaching the age of 90 years.

drinkable

Professor John Speakman of the University of Aberdeen, a co-author of the research, said: "This study shows that the common suggestion of drinking 8 glasses of water - or about two liters per day - is probably too high for most people."

While there is no obvious harm from drinking higher amounts of water, the British newspaper says that obtaining safe drinking water can be expensive, these days.
