Limiting your child’s recreational screen time to less than two hours a day, and ensuring sufficient sleep and physical activity, can significantly improve their brain function, a study has found. 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, according to the study published in The Lancet Child & Adolescent Health journal.
“Behaviour and day-to-day activities contribute to brain and cognitive development in children, and physical activity, sedentary behaviour, and sleep might independently and collectively affect cognition,” said Jeremy Walsh, of CHEO Research Institute in Canada. “Evidence suggests that good sleep and physical activity are associated with improved academic performance, while physical activity is also linked to better reaction time, attention, memory, and inhibition,” said Walsh.
“The link between sedentary behaviours, like recreational screen time, is unclear as this research is in the early stages and it appears to vary depending on the types of screen-based activity,” he said.
