Finding your digital sweet spot: how much is too much?
Are you consuming social media content, or is this content consuming you? A research team in the United States has come up with a screen time threshold in order to maintain a positive state of mental well-being. Teens and young women have long dominated the conversation around social media and mental health. To get the full picture, research needs to isolate social media from general screen habits and see if this pattern holds across different populations over time. A major study led by the University of Cincinnati (UC) and Northwestern University is the largest yet to track how social media affects mental health throughout an entire adult life.
The danger zone of screen time
From 2014 to 2024, 11 surveys of around 183 000 American adults between the ages of 18 and 70 tied increased daily social media use directly to higher self-reported depression. Volunteers ran through a yes-or-no list of 31 health conditions, including depression. The researchers used computer models to sift through dozens of lifestyle habits and demographic factors. Social media time predicted depression far better than TV, gaming or email. Overall, the data showed that once daily screen time exceeded 150 minutes, the connection between social media and depression became impossible to ignore. The findings were published in the Nature Portfolio journal ‘Mental Health Research’(opens in new window). “When it comes to depression and social media, the argument is salient across scientific test after test of those 11 years,” commented corresponding author and UC College of Engineering and Applied Science professor Hans Breiter in a news item(opens in new window). “It’s a damning picture. Social media is harmful for individuals across the lifespan. We should not subject ourselves to a product using addiction science to optimise our viewing time.” He added: “Mental health and happiness are about engaging the world and having purpose, not passively watching something for hours.”
Where do you draw the line?
“Initially, social media was a social outlet with people you knew,” co-author and UC senior research associate Nicole Vike told ‘USA Today’(opens in new window). Social media has fundamentally changed. These days, it’s driven by consuming content from people we don’t even know, she explained. “It’s crazy how addictive it can be. Look at chronically online content creators. They often have to take a monthslong hiatus from being online for their mental health.” “Social media is a common marker of our cultural age much like the automobile was more than a century ago,” stated co-lead author Martin Block, professor emeritus at Northwestern University. “But social media has an important negative effect through its association with depression, much like the automobile is associated with injuries from crashes and pollution.” While the link is hard to ignore, the authors stop short of claiming social media causes depression. However, instead of guessing what counts as ‘too much’ scrolling, the research community finally has a concrete 150-minute baseline to work with in the future.
