Amelia Kennedy, 19, of Royersford, Pa., a point guard on the Catholic University of America, Washington, basketball team who will begin her sophomore year in the fall, uses TikTok, Snapchat, Instagram, and YouTube regularly.
How regularly? She estimates 7 hours a day and about 9 on weekends. She’s aware of the time-wasting potential. “If my mom says, ‘Do dishes,’ and I say, ‘5 more minutes,’ it can be longer,’’ she said.
Now imagine the challenge of cutting that 7 or 9 hours a day of social media use down to 30 minutes.
A very tall order, considering a 2022 Pew Research Center survey of more than 1,300 teens found 35% are “nearly constantly” on at least one of the top five social media platforms: YouTube, TikTok, Instagram, Snapchat, and Facebook.
Researchers from Iowa State University, Ames, recently took on that daunting challenge, limiting a group of students to only 30 minutes of social media a day to see what happens. Two weeks into the study, the students reported improvement in psychological well-being and other important measures, including sleep quality, compared with a control group assigned to continue using social media as usual.
And the dreaded FOMO, or fear of missing out, didn’t happen, the researchers said. At the end, the students were rethinking their social media use and feeling positive about it.
As social media becomes more common and youth mental health more endangered, experts are sounding the alarm. In late May, U.S. Surgeon General Vivek Murthy, MD, issued an advisory on social media and youth mental health, calling for tech companies to do better, policymakers to strengthen safety, and researchers to get more information, among other actions.
After that, the Biden administration took actions including the launch of a task force on kids’ online health and safety. The American Psychological Association has issued recommendations on social media use in youths. And the Social Media Victims Law Center in Seattle has sued numerous social media companies for online activity resulting in death and other tragedies.
While experts acknowledge that much more research is needed to sort out how to balance social media’s risks and benefits to preserve youth mental health and prevent such disasters, the new Iowa State study, as well as other recent research, suggests that
Goal: 30 minutes a day
In the Iowa State study, 230 undergraduate students were assigned to one of two groups, with 99 in the 30-minute-a-day social media use group and 131 in the “usual” or control group, which made no changes. For those in the intervention group, “we sent a daily reminder email,” said Ella Faulhaber, a PhD candidate at Iowa State and the study’s lead author. It simply reminded them to limit social medial use to the 30-minute maximum.
At the study start and end, all participants provided a screenshot of their weekly social media usage time. The researchers gave both groups a battery of tests to assess anxiety, depression, loneliness, fear of missing out, and negative and positive feelings.
“By limiting their social media time, that resulted in less anxiety, less depression, less FOMO, fewer negative emotions, and greater positive emotions,” said Douglas Gentile, PhD, a distinguished professor of psychology at Iowa State and a study coauthor. “We know that it is the limiting [of] the social media that is causing that.”
Ms. Faulhaber recalled one participant who mentioned having trouble at first adjusting to the 30-minute time frame, but once sleep improved, it was easier to stick to that guidance. Another who gave up phone use at bedtime found: “Instead of looking at my phone, it was much easier to go straight to bed.”
Sleep improvements, of course, affect many parts of physical and mental health, Dr. Gentile said. And the study also showed that even with reduced screen time, “we can still get the benefit of being connected.” Those who didn’t make the 30-minute mark, but cut back, got benefits, too, the researchers said.
