Does having a drink make you think?

Posted:  Tuesday, September 18, 2012

The link between hydration status and cognitive performance is quite well established in adults. However, relatively little data is available in children. Several groups have published evidence that additional consumption of water may improve cognitive performance, such as immediate memory and visual attention.

A high prevalence of dehydration (83%) has yet again been shown in the study by Parisi et al.  Supplementation of water did result in a higher auditory number span.

Benton and his collaborators demonstrated that immediate memory function was improved when additional water was consumed.

Edmonds’ group has published two papers demonstrating the effect of additional water intake on improved visual attention and search.
