A new study has found that social media could be affecting the sleep of young adults. The study is a project of researchers at the University of PiiLshurgh's School of Medicine, They found that young people who often use social media are more likely to suffer from sleep than

those who use social media less.

The researchere say doctors should ask young adults about their use of social media when treating sleep issues. “This is one 0f the pieces of evidence that social media use really can affect your sleep,” saidJessica C, Levenson. She is a postdoctoral researcher in the university's Difpartment of Psychiatry. She was the lead author of a report on the study. The researchers set out to exmine the connection belween social media use and sleep among young adults.

The researchers wanted to find out how often young people used social media sites like Facebook, Twitter and etc.，Far the study, they gave questionnaires to nearrly 1, 800 adults, aged 19 to 32, On average，members of the study group used social media sites one hour a day. They also visited various social media accounts 30 times per week. Thirty percent of ihe study's participants reported havingserious problems with sleepping. Those people who used social madia a lot were three times more likely Id have a sleep disorder. And those who spent the most time on serial media were two times as likely to suffer from sleep disturbances.

Frequent checking is big part of the problem. Levenson said the number of a person visits media is a better predictor of sleep problems than overall time spent on serial metdia. If this is true, she adda,then practices that stop such behaviors may be most effective.

Researchers say social media can influence sleep patterns in a number of ways, People can lose sleep by staging up too late looking at social media. Sensitive issues about on social media pan cause” emotional ,cognitive or physiological” excitement . Using an electrenic device can disturb a body's natural sleep rhythms because of the light coming from cell phones or computer screens. The researchere note that in some cases,, young adults who have a hard time sleeping may use social media to help them fall asleep.

“It also may be that both of these hypotheses (假定）are true,” says Brian A. Primack. He is director of the Center for Research on Media, Tehnology and Health. He is also the study's senior aurhor. Primack says，“ Difficult sleeping may lead to increased use of social media, which may in turn lead to more problems sleeping. This cycle may be particularly problematic with social media. Many forms of social media involve interractive screen time thal is stimulating(刺激） and rewarding and, for thoae reasons, can keep you awake. ”
