Effects of fluid ingestion on cognitive function after heat stress or exercise-induced dehydration

Editor(s): C. Cian, P. A. Barraud, B. Melin, C. Raphel.

Cian et al. demonstrated that dehydration induced by heat stress or exercise can have detrimental effects on short-term memory, working memory and visuo-motor abilities. However, although no beneficial effect on cognitive variables could be demonstrated with fluid ingestion, it did prevent decrement in long-term memory as compared to control and dehydration.
