A new study out of Canada suggests teenagers should spend less time looking at screens and more time involved in activities. The findings published in the journal Preventive Medicine were based on a survey of 28,000 7th graders in British Columbia. They answered questions about how much time they spent watching TV, streaming videos, playing video games versus how much time they spent in extracurricular activities like sports and music programs. Then they ranked how good they felt about each day when they woke up. From their answers, researchers concluded that teens who spent more time in activities were mentally healthier and less anxious and depressed than those who spent more time with screens.

And the study suggested that extra screen time was especially harmful to girls. For them, researchers say the negative effects were stronger. So how much screen time is too much? The Canadian Pediatric Society says all adolescents should have less than two hours of screen time per day and that guideline factored into the study. But it's important to point out that the information for it was gathered between 2014 and 2018, years before the coronavirus pandemic hit.
And this year, with fewer opportunities to see friends and participate in extracurricular events, teenagers have shown higher levels of depression and anxiety according to other research. The lead author of the Canadian study says even though it's harder to do it's still important to find ways for teens to safely get involved with programs and hobbies away from screens.
