A new American review (July 2018) has revealed how dehydration can affect cognitive function, with just a couple of hours of vigorous activity in the summer heat without drinking fluids enough to affect concentration.

Carried out by the Georgia Institute of Technology, the new meta-analysis looked at 33 studies with 413 subjects in total and focused on the effects of acute dehydration on cognition, which anyone can experience during exertion, heat and/or not drinking.
