Every day we come with thousands of popular tips, rules, and safeguards, many of which turn out to be delusions. We are launching a series of materials in which we will dissect popular opinions and find out if they are related to reality. Today we figure out how much water you need to drink per day.

So drink or not drink?

Water is certainly healthy – if only because it saturates the body and does not contain calories. But studies that would confirm the rate of 2 liters per day do not exist today. The arguments in favor of high water consumption, which are found in the media, boil down to the following: our body consists mainly of water (50-70% of the mass), like blood, muscles, brain, and bones, and therefore the body needs water to function normally, – not less than 2 liters. And if it is difficult to argue with the first conclusion, then the second is not based on anything.

Even in the publication of the National Food and Nutrition Board of the United States, it was mentioned that the rate of 2.5 liters indicated by it includes not only drinking water but also all other drinks, as well as all food, which also contains a significant amount of water. Therefore, to get enough water, you do not need to drink several bottles a day – you just need to eat right. For those who want to make sure that their body is getting enough water, there are mobile applications that help you calculate what a cup of milk gave you and how much a cup of coffee took away.

About coffee and water

In large quantities, anything can be harmful – even a seemingly harmless drink like tea. But several cups of coffee a day are even healthier than one. This follows from the recent regulations adopted by a group of American experts. The regulations were developed for the government food and drug administration and the USDA.

Experts have traced a pattern that shows that several cups of coffee a day reduce the risk of heart disease and type 2 diabetes, while the risk of other diseases does not exactly increase. And if so, then you should not deny yourself the pleasure if after one cup of coffee you want a second, and after the second – a third. The main thing is not to overdo it with sugar – it is he, as follows from the standards, the source of many troubles. So, drinking three to five cups of coffee a day will not only not harm your health, but also reduce the risk of cardiovascular diseases and diabetes.

It happened that people died after drinking too much water – that is, from water intoxication. Drinking water is often recommended to lose weight. But it remains unclear whether water significantly reduces food intake, how long the effect lasts, and how much fluid is needed to affect satiety. A study by the American Society of Clinical Nutrition suggests that water in foods (such as chicken soup) may do a better job of preloading the next meal than the same amount of water taken alone. The link between water consumption and long life expectancy has also not been established.

Interestingly, what happened when people died after drinking too much water – that is, from water intoxication. True, ecstasy influenced some of the dead people, which increases the feeling of thirst. humans evolved by performing hard physical labor in hot and dry conditions. We can get less water than usual without any problems, while even a slight intoxication with water will lead to much more sad consequences. In simple terms, drinking too much water is just as bad as not drinking it at all.
