A new study says that parents should limit the recreational screentime of children to two hours a day to improve their cognition، as the Technical Times said.
When paired with ample sleep and physical activity، kids aged 8 to 10 were able to perform better in tests that measured language abilities، episodic and working memory، executive function، attention span، and processing speed.
The study was conducted by researchers from the CHEO Research Institute's Healthy Active Living and Obesity using data from the U.S. National Institute of Health. Their findings were published by The Lancet Child & Adolescent Health. The study involved 4،524 children from about 20 study sites across the United States. Parents were also surveyed to find out the habits of their children، including the amount of sleep they get every night، how often they are physically active، and how much of their time was spent glued to the television، a smartphone، or a computer.
The children were then tested across six kinds of cognitive skills، adjusting the results based on household income or other factors that might affect their performances.
Unsurprisingly، the researchers found that children who met the recommended amounts of sleep، physical activity، and screentime performed better during the tests.
