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

     ▲     For them, researchers say the negative(消极的) effects were stronger. So how much screen time is too much? The Canadian Pediatric Society says all teenagers should have less than two hours of screen time per day. But it's important to point out that the information for it was gathered between 2014 and 2018, years before the coronavirus pandemic (新冠疫情) hit.

This year, with fewer chances to see friends and join in activities, teenagers have shown higher levels of depression (抑郁) and worries according to another 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 have programs and hobbies that are away from screens.
