Study: Kids who drink more water appear to be better at multitasking

Led by researchers at the University of Illinois, the new study looked at 75 children aged nine to 11 years old.

The children were placed into three groups; one group maintained their usual water intake for a period of four days, one group drank half a liter for four days, and the third group drank 2.5 litres of water a day for the same period.

The researchers measured the children’s urinary hydration and cognitive performance at the start of the study and after the four days.  The findings, published in The Journal of Nutrition, showed that as expected, drinking more water for several days improved the children’s hydration.
