And the heavier users of social media get to bed later and get poorer quality sleep. The new study was based on self-reported survey data from nearly 12，000 teenage participants in the UK Millennium Cohort Study. Megan Moreno， a researcher at the University of Wisconsin-Madison， says that social media is too often described as either entirely good or bad， when the reality is more complicated for teens. “Social media may have its problems， but it is the way that they stay in touch with each other，” she says. Perhaps unsurprisingly， the study found a link between high social media usage and poor sleep patterns. Specifically， teens who report heavier social media use go to sleep later. And， the study authors note， late bedtimes are linked with poorer academic and mental health outcomes. Holly Scott， a researcher at the University of Glasgow， isn’t sounding the alarm. She says，“It’s easy to look at the results of this and think，‘We should just get teenagers to spend less time on social media.’ I think that’s an understandable response， but what I really encourage people to do is look beyond that.” She says people should pay attention to the “important emotional and social factors” at play when teenagers are using social media. Scott emphasizes that the study is pointing to a correlation between social media and poor sleep， but not necessarily demonstrating cause and effect. “Certainly some teens do say that they struggle to get rid of social media at night — they might be worried about missing out on things， or affecting their friends by not answering messages — and they stay up late from that，” she says. “But maybe for some of those young people they have a naturally later body clock， and are passing their free time at night on social media until they’re ready to fall asleep.” 1.What’s the purpose of the new study in the UK？（　　） A.To f ... ...
