How Brief Breaks from Sitting May Benefit Cognition

Breaking up long periods of sitting with brief movement may improve certain thinking skills, with the strongest evidence showing benefits for memory and executive function Walking and other gentle activities are enough to interrupt prolonged sitting, so supporting your brain throughout the day doesn't require repeated strenuous workouts Just four three-minute activity breaks during 80 minutes of sitting helped adolescents maintain the brain's oxygen-rich blood response during a demanding memory task Some improvements in working memory, attention and reaction speed persisted for up to 30 minutes after activity ended, suggesting the benefits don't necessarily disappear when you sit back down Regular movement breaks complement rather than replace exercise, so aim to interrupt sitting throughout the day while gradually working toward an hour of daily walking and strength training twice a week
