Are your social media habits affecting your sleep?

Young adults who spend a lot of time on social media during the day or check it frequently throughout the week often get less sleep than their peers who use social media less, a new study suggests.

The findings, published in the journal Preventive Medicine, indicate that doctors should consider asking young adult patients about these media habits when assessing sleep issues.

“This is one of the first pieces of evidence that social media use really can impact your sleep,” says lead author Jessica C. Levenson, a postdoctoral researcher in the psychiatry department at the University of Pittsburgh. “And it uniquely examines the association between social media use and sleep among young adults who are, arguably, the first generation to grow up with social media.”

For the study, researchers sampled 1,788 US adults ages 19 through 32, using questionnaires to determine social media use and an established measurement system to assess sleep disturbances.

The questionnaires asked about the 11 most popular social media platforms at the time: Facebook, YouTube, Twitter, Google Plus, Instagram, Snapchat, Reddit, Tumblr, Pinterest, Vine, and LinkedIn.

On average, the participants used social media a total of 61 minutes a day and visited various social media accounts 30 times a week. The assessment showed that nearly 30 percent of the participants had high levels of sleep disturbance.

The participants who reported most frequently checking social media throughout the week had three times the likelihood of sleep disturbances, compared with those who checked least frequently. And participants who spent the most total time on social media throughout the day had twice the risk of sleep disturbance, compared to peers who spent less time on social media.

“This may indicate that frequency of social media visits is a better predictor of sleep difficulty than overall time spent on social media,” Levenson says. “If this is the case, then interventions that counter obsessive ‘checking’ behavior may be most effective.”

More study is needed, particularly to determine whether social media use contributes to sleep disturbance, whether sleep disturbance contributes to social media use—or both, says senior author Brian A. Primack, assistant vice chancellor for health and society.

For example, social media may disturb sleep if it is:

Displacing sleep, such as when a user stays up late posting photos on Instagram.Promoting emotional, cognitive, or physiological arousal, such as when engaging in a contentious discussion on Facebook.Disrupting circadian rhythms through the bright light emitted by the devices used to access social media accounts.

Alternatively, young adults who have difficulty sleeping may subsequently use social media as a pleasurable way to pass the time when they can’t fall asleep or return to sleep.

“It also may be that both of these hypotheses are true,” Primack says. “Difficulty 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 because many forms involve interactive screen time that is stimulating and rewarding and, therefore, potentially detrimental to sleep.”
