You need plenty of water during exercise so that your brain gets the full benefits of working out, researchers say.
"Middle-age and older adults often display a blunted thirst perception, which places them at risk for dehydration, and subsequently may reduce the cognitive health-related benefits of exercise," says Brandon Yates, of Spaulding Rehabilitation Hospital in Boston.
It was noted that brain function decreased with dehydration.
"Older adults should adopt adequate drinking behaviors to reduce cognitive fatigue and potentially enhance the cognitive benefits of regular exercise participation." American Physiological Society.
