Turns out water is excellent for mental performance.

In a controlled study, researchers from Universities of East London and Westminster found that students who drank from a water bottle during exams had scores on average between 5-10% higher than those who didn't hydrate!

Drinking enough water has also been shown to improve mood and lower stress, which also add up to improved mental functioning.

Staying hydrated is important - a study in the British Journal of Nutrition showed even mild fluid deprivation decreases alertness and increases sleepiness, fatigue and confusion.
