Scientists have disproved the myth that coffee causes dehydration

Ученые опровергли миф о том, что кофе приводит к обезвоживанию

Caffeine is a diuretic, however, it became clear that not to the same extent as is commonly believed.

The proponents of popular theories about what you need to drink two liters of water a day, often in those litres should not be counted coffee and tea as drinks that have a diuretic effect.

Researchers from Australia’s Griffith University found out whether or not a soil is a point of view. For starters, they analyzed the famous study of 1928, which became the starting point for the origin of the myth that coffee dehydrates.

Indeed, caffeine is a diuretic, however, it became clear that not to the same extent as is commonly believed.

The study of 1928 was held not quite as modern. It was attended by only three people, which for several months had to drink tea, coffee or water. And diuretic effect really did occur, but only in case, if this man is two months did not drink tea and coffee at all.

Similar results have been obtained, and after almost a hundred years, but on a bigger sample. The new study included 59 healthy people, the consumption of which was monitored for 11 days.

First, the caffeine intake of each participant was stable for six days at a level of about 3 mg per kilogram of body weight (two or three cups of coffee a day). After this period, the consumption of caffeine has changed from zero to the average level.

It turned out that with this approach, the regular consumption of caffeine-containing beverages, does not lead to chronic dehydration. In other words, a diuretic effect from coffee with regular use is not different from the diuretic effect of water.

Earlier, scientists have found that drinking coffee four hours before bedtime has no negative effects on humans.
