Limiting children's recreational screen time to less than two hours a day linked to better cognition
September 27, 2018, Lancet
Only one in 20 US children in the study met the full recommended guidelines on recreational screen time, physical activity and sleep.
Limiting recreational screen time to less than two hours a day, and having sufficient sleep and physical activity is associated with improved cognition, compared with not meeting any recommendations, according to an observational study of more than 4,500 US children aged 8-11 years old published in The Lancet Child & Adolescent Health journal.
Taken individually, limited screen time and improved sleep were associated with the strongest links to improved cognition, while physical activity may be more important for physical health.
