Almost everyone knows that you need to drink at least two liters of water a day.. But it's not so simple with this question. If at a younger age people still adhere to these recommendations, then at an older age the desire to drink water disappears almost completely. In a new study published by the Journal of Physiology, scientists have reported the effects of dehydration in older men, according to Pannochka, an online publication for girls and women aged 14 to 35.. net When a person is hot, the hypothalamus produces sweat from the skin, which cools our body. Further, normally, a person begins to feel thirsty, replenishing the lost fluid. Sweating too much with minimal water intake can cause dehydration.

Lack of water will first of all cause disruption of the heat transfer process associated with sweating.. As a result, during the heat, the body will not be able to cool itself, which will lead to the development of heatstroke.. As the body ages, the natural system that regulates body temperature is disrupted.

Canadian scientists from the University of Ottawa have found that the lack of thirst in older people can lead to various kinds of malfunctions in the body.. For this reason, even if the elderly are not thirsty, the researchers recommend that they take care of replenishing the body with water.. This is especially true when performing heavy physical work or exercise..

An experiment carried out with the participation of 20 men of different ages (18-67) showed that even an increase in the concentration of salt in the blood (after the introduction of saline solutions) and exercise that caused sweating in the elderly could not cause thirst.

Researchers believe that some chronic diseases, such as diabetes, may have a direct relationship with impaired heat transfer and hydration.. Further research may help explore the relationship between regulation of body temperature and hydration status, and the development of certain chronic conditions..
