Researchers have linked harmful effects of screen time to adolescents’ mental health. Times exceeding two hours a day for girls and four hours a day for boys were found to lead to negative effects.
UQ School of Health and Rehabilitation Sciences researcher underwent a global study of more than 577,000 adolescents aged 13 to 15 years across 42 high-income countries. Data gathered revealed, while there was some benefit to the first hour of viewing, after 75 min. in girls and 105 min. in boys, detrimental effects occurred. Excess negative effects can include depression, obesity, poor quality of life, unhealthy diet, and decreased physical and cognitive abilities. For this study screen time did not include educational (schooling) screen time. This study was only just published in The Lancet Child & Adolescent Health
The study arrived at a formula of ‘one hour of physical activity and no more than two hours of screen time a day provided optimal mental wellbeing’.
Lack of physical activity, social connection, and skills occur and can have a negative effect on global wellbeing and individual mental health.
