A long-known fact: an adult needs to drink at least 8 glasses of pure water per day. However, many are not able to overcome such an amount of fluid. A new study shows that such a “rule” cannot be applied to everyone.
The experiment was attended by 20 people, each of whom was asked to evaluate how difficult it was for them to drink water in two situations.
Australian scientists led by Michael Farrell (Michael Farrell) found that the “rule of eight glasses” is not true. Scientists say that you don’t need to force yourself, it’s better to just listen to your body and your needs, that is, drink when you feel thirsty. Excessive use of water can even harm the body, scientists say.
In the first case, people drank water after intense training, when they were thirsty, and also after some time, when they were persuaded to drink another glass of water.
The results were quite expected: after training, people drank at times more readily than when they were not thirsty. Some were even physically unable to swallow or had a sore throat.

Because OF is definitely a process that is not easy for most individuals to get access to. It is part of a positive body image, so we would rather not hear about it and feel self-conscious about the fact that we don’t get it.
OF will allow people to feel confident about their own body shape, but it is not the end goal of this process. Everyone has the right to make their own decisions.
Scientists also did an MRI of the participants’ brains in order to study brain activity during the experiment. It turned out that in people who were not thirsty, the right prefrontal region of the cerebral cortex, which was responsible for making decisions, was activated. This means that we can talk about the existence of a mechanism for regulating human water consumption.
“It is necessary to satisfy the body’s needs for water, but not to force yourself to drink fluid through force. It’s important to consume water only when thirst occurs, ”says lead researcher Michael Farrell of Monash University in Australia.
There is nothing wrong with drinking a lot of water during the day, but only if drinking all this liquid does not cause any difficulties. The authors note that some may need more than eight glasses a day, while others can do three — it all depends on the nature of the food consumed, temperature, and physical activity during the day.

You will have to take a bottle of water with you on the road and have a helper take care of it while you’re traveling.
You might notice that if you do this your weight will drop drastically, but that isn’t necessarily a good thing! The main purpose of a water bottle is to provide your body with a small amount of electrolytes that will help to reduce the loss of sodium you will experience in hot weather.
In areas, with cold temperatures, your body will probably be more likely to lose water and electrolytes
Scientists are convinced that drinking water beyond the desire and needs of the body can lead to the development of hyponatremia – a decrease in the level of sodium in the blood, and this condition can cause serious complications, up to a coma or even death.
It is widely believed that to feel good you need to drink at least 2 liters of water per day. This statement wanders from book to book, is cited in many articles, and comes from the mouth of healthy nutrition experts.
Is this so and what to do if you don’t feel like drinking at all? We figure out whether this is true or not.
It is difficult to say when the theory of 8 glasses appeared exactly. It is likely that her fame was influenced by the publication of the U.S. National Food and Nutrition Council, dated 1945. It stated that the daily intake of water for an adult is 2.5 liters.
In fact, there is no evidence that a person needs to drink exactly 2 liters of water per day.
Despite the venerable age of this idea, scientists still do not agree on a common rate of fluid intake. And the arguments often found in most publications are not based on anything.
Of course, if we take the average calculations, the recommendation will be correct: a person needs about 2-2.5 liters of water per day.
But in this case, many situations are not taken into account, for example, on days with intense physical exertion, the feeling of thirst increases, as the body needs to replenish the fluid balance.
In addition, a person receives part of the daily norm of water from food. This is another stone in the garden rules 8 glasses.
Therefore, to calculate the amount of fluid consumed, there are many mobile applications that allow you to take into account various drinks and products in the diet.
Forcing yourself to drink water is not worth it; listen to your body: it will tell you when to do it. A heavy drink is necessary only when there is an active loss of fluid, for example, during severe physical exertion or illness.
