The positive impact of drinking water on the health of the human body is known for quite some time. Water is the main fluid in the body and its value is difficult to overestimate. It is water that provides transportation function and constant temperature support, and is also a key element of all reactions that take place in the cells of a living organism.
Recent studies by British scientists have shown that water can have a beneficial effect on the brain's ability to work. The London medical publication published information that confirmed that several glasses of cold drinking water could significantly affect brain performance .
A group of scientists from popular universities in London conducted several studies aimed at analyzing the effect of water on the functions of the human body. It turned out that water can have an impact not only on the general state of human health, but also on cognitive functions, on the brain's ability to work and even on mood. About 36 volunteers aged 27 to 32 years took part in the experiment. The aim of the study was to determine the possible impact of water on the mindfulness and cognitive functions of a person. Before passing the various tests, participants were divided into two groups, one of which received whole-grain bars and a rather large amount of cold water, and the second - only cereal products. During the experiment, scientists hoped to trace the effect of water on test results, so each participant in the first group had to drink at least half a liter of drinking water. Half an hour after the meal, participants in the experiment were offered various tests for intelligence, mindfulness, and reaction speed.
The results of the study confirmed the fact that cold water can improve the performance of the brain. Those participants who drank water before the experiment started were more intelligent and scored more correct answers. Also, experts noted that people who drank more than 700 milliliters of water (about three glasses) showed results 14-15% better than the rest of the experiment.
The head of the study believes that the main reason for this behavior of the body is that water can remove the load from some areas of the brain, which are responsible for the processing speed of the information received. Another reason may be the fact that a sense of thirst can cause quite a strong discomfort and distract a person from solving the set tasks.
However, not all physicians agree that the lack of water in the body has a negative impact on the reaction rate and the perception of new information. Early studies of American specialists have shown that a sense of thirst can lead to a higher speed of solving the tasks posed and more correct answers when passing the tests for intelligence. The reason for this behavior of the human body, according to experts from the University of California, is vasopressin - a hormone, the secretion of which increases significantly when the volume of fluid in the cells decreases. According to American physicians, vasopressin can influence the care and speed of human reaction.
At the moment, scientists plan to conduct several experiments that will help determine the effect of temperature and the degree of water purification.
