This new study published in the Journal of Epidemiology and Community Health found that even 6-9 minutes of physical activity per day can have a positive effect on brain health. Using activity monitors to track the 24-hour movements of nearly 4,500 people in the UK, the study found that those who engaged in more vigorous activities for longer periods of time had better cognitive performance. The findings suggest that even small amounts of physical activity can have a positive effect on brain health and encourage people to be mindful of their physical activity levels.
