A simple glass of water can dramatically improve exam results. Research by researchers at the University of East London has shown, that children, who were asked to drink a glass of water before completing school tests, obtained even better results 30%. According to the authors of the study, the mechanism of this dependency is not entirely clear, though it seems, that properly moistened nerve cells can transfer information more efficiently. Age children under study 7-9 years, obtained better results in tests checking spatial attention and memory, however, there were no differences in short-term memory tasks.
