Hydration, Nutrition and Cognition Research Unit
This unit explores the effect of hydration and drinking water on cognition and the effect of nutrition on cognition, the brain and mood.
We are particularly interested in the positive effects of water consumption on cognitive performance, both in children and in adults. Recent work in adults includes measuring hydration using bioelectrical impedance and relating this to cognitive performance measured using CANTAB. Recent work in children includes papers on the positive effects of water consumption on cognition.
The unit is also interested in the effect of nutrition on cognition, the brain and mood

Drinking water improves exam grades, research suggests — By Katherine Sellgren
Students who take water into the examination hall may improve their grades, a study of 447 people found. Controlling for ability from previous coursework results, researchers found those with water scored an average of 5% higher than those without.

How to do better in your exams: Drinking a glass of water can boost your results by a grade — By Fiona Macrae
Forget expensive private tutors and brain-boosting vitamins. The key to exam success could be as simple as a glass of water. Students who took a drink into the exam hall did up to 10 per cent better than those who did not — the difference between a grade.
