In the study, respondents who drank three glasses of water before following cognitive tests were able to get better grades than those who do not drink water at all.
Researchers speculate that the sensation of thirst can lose concentration. So by drinking water, the concentration can be recovered and one is able to do his job with more focus.
Even so, it turns out to drink plenty of water is also not always good. On different tests, researchers found that consumption of water does not give better results on respondents.
"There is a hormone called vasopressin which activate the thirst response is also related to the concentration and sexual stimulation. However sometimes certain cognitive tests, such as remembering words, has nothing to do with it," said Caroline Edmonds, researchers from the University of East London School of Psychology at England.
As reported by Mother Nature Network, previously there is research that says that dehydration can reduce mental performance. But there is no strong evidence that the drinking water, the concentration can be increased.
The results are then reported in the journal Frontiers in Human Neuroscience.
