(Andrew Duffy/ Ottawa Citizen) — A large, international study that involved more than half a million teenagers has distilled a clear, simple formula for the improved mental wellbeing of adolescents: more exercise and less screen time.
Published earlier this week in The Lancet Child and Adolescent Health, the study was the product of a collaboration between Dr. Mark Tremblay, a senior scientist at the CHEO Research Institute, and Australia’s Dr. Asad Khan, of the University of Queensland.
The researchers found that mental wellbeing declined when adolescents (13 to 15 years old) indulged in more than two hours of recreational screen time a day. (…)
