Parisi et al have reported in this paper a high prevalence of dehydration (83%) in children and a negative correlation between urinary osmolality and auditory number span. High urinary osmolality was linked with dehydration. Therefore, drinking water during a school day can influence some aspects of cognitive performance such as short-term memory.
