Children who meet Canadian recommendations for screen time, sleep, and exercise have better cognition than their peers who don't meet the recommendations — and screen time seems to have the largest effect — suggests a study in the Lancet Child and Adolescent Health.
Canadian 24-Hour Movement Guidelines for Children and Youth call for no more than 2 hours of recreational screen time daily, 9 to 11 hours of sleep nightly for those ages 5–13, and at least 60 minutes of moderate-to-vigorous aerobic activity daily.
For the study, researchers examined survey data on roughly 4500 U.S. children aged 8 to 11 years. Some 37% met the screen time recommendation, 51% met the sleep recommendation, and 18% met the activity recommendation. Children who met all three recommendations (5%) had better global cognition scores than those who met none of the recommendations. Additionally, children who met the screen time recommendation alone, or both the screen time and sleep recommendation, had better cognition than those who met no recommendations.
A commentator observes, "Each minute spent on screens necessarily displaces a minute from sleep or cognitively challenging activities."
