Just How Harmful Is Social Media? Our Experts Weigh-In.

September 27, 2021

A recent investigation by the Wall Street Journal revealed that Facebook was aware of mental health risks linked to the use of its Instagram app but kept those findings secret. Internal research by the social media giant found that Instagram worsened body image issues for one in three teenage girls, and all teenage users of the app linked it to experiences of anxiety and depression. It isn’t the first evidence of social media’s harms. Watchdog groups have identified Facebook and Instagram as avenues for cyberbullying, and reports have linked TikTok to dangerous and antisocial behavior, including a recent spate of school vandalism.

As social media has proliferated worldwide—Facebook has 2.85 billion users—so too have concerns over how the platforms are affecting individual and collective wellbeing. Social media is criticized for being addictive by design and for its role in the spread of misinformation on critical issues from vaccine safety to election integrity, as well as the rise of right-wing extremism. Social media companies, and many users, defend the platforms as avenues for promoting creativity and community-building. And some research has pushed back against the idea that social media raises the risk for depression in teens. So just how healthy or unhealthy is social media?

Two experts from Columbia University Mailman School of Public Health and Columbia Psychiatry share their insights into one crucial aspect of social media’s influence—its effect on the mental health of young people and adults. Deborah Glasofer, associate professor of psychology in psychiatry, conducts psychotherapy development research for adults with eating disorders and teaches about cognitive behavioral therapy. She is the co-author of the book Eating Disorders: What Everyone Needs to Know. Claude Mellins, Professor of medical psychology in the Departments of Psychiatry and Sociomedical Sciences, studies wellbeing among college and graduate students, among other topics, and serves as program director of CopeColumbia, a peer support program for Columbia faculty and staff whose mental health has been affected by the COVID-19 pandemic. She co-led the SHIFT research study to reduce sexual violence among undergraduates. Both use social media.

What do we know about the mental health risks of social media use?

Mellins: Facebook and Instagram and other social media platforms are important sources of socialization and relationship-building for many young people. Although there are important benefits, social media can also provide platforms for bullying and exclusion, unrealistic expectations about body image and sources of popularity, normalization of risk-taking behaviors, and can be detrimental to mental health. Girls and young people who identify as sexual and gender minorities can be especially vulnerable as targets. Young people’s brains are still developing, and as individuals, young people are developing their own identities. What they see on social media can define what is expected in ways that is not accurate and that can be destructive to identity development and self-image. Adolescence is a time of risk-taking, which is both a strength and a vulnerability. Social media can exacerbate risks, as we have seen played out in the news.

Glasofer: For those vulnerable to developing an eating disorder, social media may be especially unhelpful because it allows people to easily compare their appearance to their friends, to celebrities, even older images of themselves. Research tells us that how much someone engages with photo-related activities like posting and sharing photos on Facebook or Instagram is associated with less body acceptance and more obsessing about appearance. For adolescent girls in particular, the more time they spend on social media directly relates to how much they absorb the idea that being thin is ideal, are driven to try to become thin, and/or overly scrutinize their own bodies. Also, if someone is vulnerable to an eating disorder, they may be especially attracted to seeking out unhelpful information—which is all too easy to find on social media.

Are there any upsides to social media?

Mellins: For young people, social media provides a platform to help them figure out who they are. For very shy or introverted young people, it can be a way to meet others with similar interests. During the pandemic, social media made it possible for people to connect in ways when in-person socialization was not possible.  Social support and socializing are critical influences on coping and resilience. Friends we couldn’t see in person were available online and allowed us important points of connection. On the other hand, fewer opportunities for in-person interactions with friends and family meant less of a real-world check on some of the negative influences of social media.

Whether it’s social media or in person, a good peer group makes the difference. A group of friends that connects over shared interests like art or music, and is balanced in their outlook on eating and appearance, is a positive. – Deborah Glasofer

Glasofer: Whether it’s social media or in person, a good peer group makes the difference. A group of friends that connects over shared interests like art or music, and is balanced in their outlook on eating and appearance, is a positive. In fact, a good peer group online may be protective against negative in-person influences. For those with a history of eating disorders, there are body-positive and recovery groups on social media. Some people find these groups to be supportive; for others, it’s more beneficial to move on and pursue other interests.

Is there a healthy way to be on social media?

Mellins: If you feel social media is a negative experience, you might need a break. Disengaging with social media permanently is more difficult­—especially for young people. These platforms are powerful tools for connecting and staying up-to-date with friends and family. Social events, too. If you’re not on social media then you’re reliant on your friends to reach out to you personally, which doesn’t always happen. It’s complicated.

Glasofer: When you find yourself feeling badly about yourself in relation to what other people are posting about themselves, then social media is not doing you any favors. If there is anything on social media that is negatively affecting your actions or your choices­—for example, if you’re starting to eat restrictively or exercise excessively—then it’s time to reassess. Parents should check-in with their kids about their lives on social media. In general, I recommend limiting social media— creating boundaries that are reasonable and work for you—so you can be present with people in your life. I also recommend social media vacations. It’s good to take the time to notice the difference between the virtual world and the real world.
