Drinking water boosts exam results

A recent study of 447 UK psychology students found that those who took water into their exams scored 5% higher marks on average than those who didn’t, after allowing for coursework grade variations.

Water was felt to have:

  • a physiological effect in improving thought processes
  • a psychological effect in alleviating anxiety.

As the researchers concluded, 'supplementing with water is a really cheap way students and educators can help get better results'.
