Both Western and domestic nutritionists unanimously assert: a person, regardless of workload and time of year, needs to drink a lot of water. It helps to improve the water-salt balance in the body. But is this statement so true? It turns out that excess fluid can cause serious damage to internal organs.


How thirst arises

According to biologists, the main reason why a person is thirsty is a change in the water-salt balance in the blood. On average, one liter of blood contains 9.45 grams of salt. Slight fluctuations in the content of this substance are possible, but only in hundredths of a gram. However, if the concentration of salt, for example, increases, then the activity of all cells of the body is disrupted, because they are supplied with blood. Its water component at such a moment decreases, and the blood thickens. And this, according to phlebologists, threatens the occurrence of blood clots, which means that the nutrition of a specific area of ​​tissue or organ will be blocked. But this is in critical cases.

As a rule, already in the first moments of a slight increase in the concentration of salts, a person feels dry mouth. This is the first signal that calls for increased fluid levels in the body. This happens, for example, in the heat, when a person sweats and the liquid evaporates.

Drinking a lot of water is destructive

It turns out that it is better for the body to drink more fluids? Not at all. It is known that the more you drink in the heat, the more you want. The body sweats more profusely at this moment, and along with the increased amount of evaporated moisture, more salt is removed from the body. And in this case, the first to suffer are the skin of the face and hands, as well as the hair.

If a person deliberately accustom himself to increased water consumption, then in normal cold weather it harms many internal organs. Domestic gastroenterologists warn: drinking too much can dilute gastric juice, it ceases to be concentrated and destructive for microbes that enter the stomach with food. Water allows them to survive, which means that the risk of developing infections increases. However, many scientists are still arguing about exactly how much liquid is excessive.

Some people believe that drinking plenty of fluids can help improve kidney function. French nephrologist Pierre Ronceau explains in his scientific work how they actually function. In order to maintain the required level of fluids in the body, the kidneys reabsorb some of the water that has already been filtered. This provides a standard urine concentration. But the more a person drinks, the less the kidneys have to save water, and the tubules, created specifically for reabsorption, work less and less over time. If the body in hot weather is without the usual access to water, then the kidneys will not be able to saturate it with the saved fluid, and dehydration will begin rapidly.

Excessive fluid intake soon fills the tissues of the liver, kidneys, they swell, and their functional properties weaken. Meanwhile, these organs play an important role in the excretory system, and when it fails, the body does not completely remove water from itself. The liquid is retained in tissue cells, edema occurs, which provoke an increase in pressure in the walls of blood vessels. Then headaches begin. Swollen lymph nodes due to increased moisture also do not cope with their task - immunity decreases, and only a few hours remain before the development of gastrointestinal infections.

Does water help you lose weight?

However, many ladies, having increased the amount of fluid intake, despite the side effects in the form of slight edema, declare real weight loss. So, for effective weight loss, you still need a lot of water?

At first, drinking plenty of water really improves the function of the intestines, it increases peristalsis, the passage of food through the departments is faster, which means that digestion products are more efficiently excreted, and the weight decreases. But after three months, the situation is changing. The pancreas and gallbladder are saturated with water, and problems arise in their work. Food is not fully processed, because the level of secreted bile and other secretions is reduced. Gradually, the intestinal mucosa also swells - more and more constipation occurs. This leads to a general slagging of the body and weight gain.

In addition, endocrinologists warn: the cells of the hormonal glands overflowing with moisture cannot fully participate in metabolic processes due to a lack of energy.

Therefore, the burning of fat and carbohydrates slows down, and this does not contribute to weight loss in any way.

Do athletes need a lot of water?

It turns out that ordinary people should not force themselves to drink a lot of fluids - this is harmful. It is possible that increased water intake is needed by athletes. But this is not the case either. Dr. Timothy Noakes, professor of sports medicine at the University of Cape Town (South Africa), in his book Exercise Dehydration: Myths and Facts, argues that high water saturation does not improve athletic performance, but rather worsens and puts the body at risk. hyponatremia (violation of water and electrolyte balance).

The professor argues that it is simply impossible to drink before the onset of thirst. This reduces concentration of attention, physical activity of muscles in both athletes and ordinary people. And if we want to be vigorous and healthy, we need to drink as much liquid as the body physically needs.
