SHOULD CHILDREN DRINK MORE WATER?: THE EFFECTS OF DRINKING WATER ON COGNITION IN CHILDREN

While dehydration has well-documented negative effects on adult cognition, there is little research on hydration and cognitive performance in children. The authors investigated whether having a drink of water improved children’s performance on cognitive tasks. Fifty-eight children aged 7-9 years old were randomly allocated to a group that received additional water or a group that did not. Results showed that children who drank additional water rated themselves as significantly less thirsty than the comparison group (p=0.002), and they performed better on visual attention tasks (letter cancellation, p=0.02; spot the difference memory tasks, ps=0.019 and 0.014).
