The results showed that teens who spent more than seven hours a day in front of screens were twice as likely to be diagnosed with anxiety or depression than those who spent an hour a day. Moderate screen use, which was about four hours a day, was also associated with a reduction in psychological well-being than one hour a day.
Given these results, the authors warn of the need to limit the use of tablets, smartphones and computers to all school-age children and adolescents by two hours per day. Being connected to the internet for a long time interferes with behaviors fundamental to life in society.
