A GLASS OF WATER
BEFORE EXAM BEATS ANXIETY




DRINKING A glass of water could help you do better in exams, researchers have
suggested. A new study found that students who took a drink, such as water,
coffee or cola, before taking an exam did up to 10 per cent better than those who did
not — the difference between a grade. It is unclear why a drink should
help, but one theory suggests that information flows more freely between brain cells
when they are well hydrated.

Researchers said that drinking water may also calm nerves, while those who
became thirsty during test time could be more easily distracted, the Daily Mail
reported. The study, which looked at hundreds of university students, compared
whether they took a drink into the exam with their final marks. The students’
overall academic ability was then factored in, to ensure that the results were not
skewed by the possibility that smarter students are also more thirsty.
