Does Hydration Status Influence Executive Function? A Systematic Review
2021, Journal of the Academy of Nutrition and DieteticsCitation Excerpt :Two investigations assessed self-reported thirst sensations before participants undergoing cognitive testing. One of these studies measured self-reported thirst after no instructions regarding fluid intake before testing63; the other measured self-reported thirst after an overnight fast (∼12 hours) of no foods or fluids.64 Rogers and colleagues63 reported that individuals with higher subjective thirst ratings performed better on a measure of sustained attention in a dose–response manner after the ingestion of 120 mL and 330 mL water.63
Infusing pleasure: Mood effects of the consumption of a single cup of tea
2016, AppetiteCitation Excerpt :Secondly, there are some indications that water consumption can improve mood. Two studies found an immediate effect on alertness, which did not seem to be sustained over time (Pross et al., 2013; Rogers, Kainth, & Smit, 2001) while a third study did not (Edmonds, Crombie, Ballieux, Gardner, & Dawkins, 2013). However in our study, arousing effects of water consumption were not apparent.
Hydration amongst nurses and doctors on-call (the HANDS on prospective cohort study)
2016, Clinical NutritionCitation Excerpt :Several studies have shown the detrimental effects of dehydration [1–3], as well as the positive effects of rehydration on cognitive function [34]. The consumption of water can reverse the cognitive impairment associated with dehydration, with the degree of improvement related to the severity of the thirst perception [34]. We demonstrated a small but significant increase in errors made during short-term working memory tasks, which was most evident in short term functional working memory (Sternberg memory test).
