A new study shows a link between sleeping problems and young adults who use social media. Researchers at the University of Pittsburgh’s School of Medicine did the study. Jessica Levenson led the team. The researchers questioned 1,800 adults from 19 to 32 years old. The team asked how much and how often they used social media sites like Facebook, YouTube, Twitter, Instagram, Snapchat, and LinkedIn. On average, members of the study group used social media sites 61 minutes a day. They also visited social media accounts 30 times a week, on average. Thirty percent of those in the study reported having serious problems with sleeping. The people who made the most individual visits to social media were three times more likely to have sleep problems. Those who spent the most time on social media were two times as likely to have difficulty sleeping. Levenson says the more visits to social media sites the young adults had, the greater their chance of having problems with sleeping. So, rather than overall time spent on social media, repeated visits might be more harmful to sleep. Brian Primack is the assistant vice chancellor for health and society of the medical school’s Health Sciences department. He says more study is needed to learn if social media use increases sleep problems or if sleep problems increase social media use. The study was published in the online journal Preventative Medicine.
