A new study on
children across the U.S., published in The Lancet Child &
Adolescent Health, finds that when they spend more than two hours on
screens every day, they tend to perform more poorly on tests of cognition. Meeting the 24-hour movement
recommendations was associated with superior global cognition. These
findings highlight the importance of limiting recreational screen time and
encouraging healthy sleep to improve cognition in children.
