Digital Smarts - Less Screen Time Equals Better Cognition
You are here
A child’s cognitive abilities can be improved by getting 9 to 11 hours of sleep a night, having at least an hour of daily physical activity and limiting screen time to less than two hours per day, a major study has found. The study assessed the behavior of 4,500 children, ages 8 to 11, and looked at their sleep schedules, how much time they spend on digital devices, and the amount they exercised. Researchers analyzed how those factors affected the children’s mental abilities, and found that only 5% of children living in the United States met all three recommendations. 63% of children spent more than two hours a day on digital devices, failing to meet the screen-time limit.
