Drinking water during an exam can significantly improve the results obtained, according to a study from the universities of East London and Westminster, in the United Kingdom. Its authors found that college students who reached higher grades were much more likely to bring a bottle of water to an exam than first-year students, or those who did not pass the first years. They then showed, through a series of experiments, that the relationship was not accidental: the students who drank and hydrated during the test were also the ones with the best grades. Researchers attribute this relationship to the fact that, on the one hand, water has a physiological effect on the brain that improves reasoning ability . But, in addition, drinking during a knowledge test relieves anxiety , which has a negative effect on the final grade. "In any case, students should stay hydrated with water on exams," conclude Chris Pawson and his colleagues, who encourage teachers to pass it on to their students.
