Effects of water provision and hydration on cognitive function among primary-school pupils in Zambia: A randomized trial
The authors conducted a randomized controlled trial in five schools with limited water access in Chipata, Zambia, to assess the efficacy of water provision on cognition. Although there were suggestive relationships between both water provision and hydration and increased scores on tests measuring visual attention, the authors did not find that provision of water or hydration impacted cognitive test scores. Key improvements to the study design are warranted to further investigate this relationship.
