Drinking water can improve brain to work faster

ISLAMABAD: Quenching your thirst during the hot weather with a glass of water can help make your brain work faster, scientists have found.
According to a study published in the journal Frontiers in Human Neuroscience, the researchers discovered that people who drank a pint of water before conducing mental tasks had reaction times that were 14 percent faster than those who did not have drink.
And, with the current heat wave in mind, the effect was most pronounced among those who were thirsty before doing the task. The findings underlines how even mild dehydration can impact on a person's mental performance, the scientists say, Science Daily Reported.
Dr Caroline Edmonds, a psychologist at the University of East London who led study, said: "Reaction time seemed to be most affected by water, particularly if the people were thirsty.
"It might be because when you are thirsty, it diverts your attention away from the task at hand. This would be important for people at work or who need to concentrate.
