Plain water improves mental ability

A recent study showed that water can stimulate certain aspects of human mental activity.

During the experiment, one group of volunteers carried out the test tasks on the cognitive functions of the brain after drank three cups (775 ml) of drinking water and the other group members to meet the challenges do not drink. It was found that quench the thirst coped with the tests better than those who did not get water.

According to published in the journal «Frontiers in Human Science» results, quenching thirst frees additional resources of attention, which leads to an increased productivity of the brain.

However, as it turned out, the water is not always a positive effect on mental activity, in some cases, providing just the opposite effect, impairing the results of brain activity.



"Probably when people drink the water, it improves the performance of certain tasks, and makes it difficult to search for solutions to the others, the same thing - if you abstain from water," - says one of the researchers Caroline Edmonds, a member of the School of Psychology at the University of East London.

In an interview with «LiveScience» Edmonds said: "The thirst in some cases, enhances mental activity, as vasopressin, is responsible for the feeling of thirst, it is also associated with the processes of attention and stimulation mental activity».

Conducted earlier experiments have shown that dehydration reduces the productivity and efficiency of the brain, and studies conducted on children, revealed that water consumption can improve memory.

Also recently, scientists have discovered that the lack of water considerably impairs the speed of reaction of the person when the volunteers are not allowed to drink, they reacted by an average of 14% slower.

By the way, if you are looking to improve the water with the help of the brain, do not drink too much of it: possible water intoxication when excess water washed from human blood sodium.
