The effect of the consumption of water on the memory and attention of children.
The impact of asking children to drink water during their school days, and its possible influence on school performance, has been little considered using intervention studies. Therefore in the afternoon the cognitive functioning of 40 children (mean of 8 years and 7 months) was assessed twice, once after drinking 300 ml of water and on another day when no water was provided. Memory was assessed by the recall of 15 previously presented objects. Recall was significantly better on the occasions when water had been consumed. The ability to sustain attention was measured by asking the child to respond to a light that followed an auditory warning after a delay of either 3 or 12 s. The ability to sustain attention was not significantly influenced by whether water had been drunk.
