I'll weigh social media's benefits against its harms — gathering the latest research on mental health, connection, and misinformation.
Social media is neither purely harmful nor purely helpful - evidence suggests impact depends on how, how much, and who is using it.
The American Psychological Association's 2023 recommendations emphasize that "social media is neither inherently harmful nor beneficial to our youth", and that proper training and monitoring are essential.
How it can be helpful
1.Connection and Community
•Evidence suggests that social media can enhance social support and community building, particularly for individuals experiencing offline isolation.
•The American Psychological Association says social media is positive for teens because the sites offer ways for teens to receive social support, explore identities, and find communities with similar interests where they feel understood by others.
•According to Dr. Murthy's advisory, some teenagers experience a benefit when they use social media to foster positive connections with others who share common interests or identities, creating a space for self-expression.
•52% of respondents said social media positively strengthened connections with friends and family, and 67% of adolescents feel social media provides people who support them through tough times.
2.Information, Creativity and Support
•The major social media benefits include friendship, social connection, emotional support, educational content, creativity, self expression, and civic engagement.
•It can also provide helpful information: 67% of U.S. girls report exposure to helpful mental health information on social media, and 78% find helpful mental health resources on TikTok.
•For many teens, the sites offer an outlet to share experiences, find support on social issues, and build artistic skills.
•According to a 2022 Pew Research Center study, 80% of teens say social media helps them feel more connected to friends. A separate Pew study found that for a majority of teens, social media was way more helpful than harmful.
How it can be harmful
1.Mental Health Risks
•The U.S. Surgeon General's advisory on social media and youth mental health, issued in May 2023, reported that up to 95 percent of young people aged 13 to 17 use a social media platform.
•There are "ample indicators that social media can also have a profound risk of harm to the mental health and well-being of children and adolescents", and that "ample indicators that social media could also harm children’s well-being".
•Adolescents who spend more than three hours per day on social media face double the risk of experiencing poor mental health outcomes, such as symptoms of depression and anxiety. That finding was also cited as adolescents who spend more than three hours a day on social media face double the risk of poor mental health outcomes, including symptoms of depression and anxiety.
•According to a research study of American teens ages 12-15, those who used social media over three hours each day faced twice the risk of having negative mental health outcomes, including depression and anxiety symptoms.
•High usage is linked to increased anxiety, depression, and loneliness. Teens may experience a "fear of missing out" (FOMO) and intense pressure to maintain a perfect online image.
2.Body Image, Sleep and Addiction
•Almost half (46%) of teens aged 13-17 report that social media makes them feel worse about their own body image, often stemming from comparing themselves to edited or unrealistic photos.
•41% of U.S. teens say social media has made their anxiety worse.
•In a review of over 100 studies involving children, adolescents, and teens, social media use was associated with higher rates of depression and anxiety, with a 13 percent increase per additional hour of daily use.
•In a systematic review synthesizing findings from 13 studies, more time spent on social media, social media engagement and interaction, investment of effort, and social media addiction were all associated with greater depression, anxiety, and psychological distress.
•Social media use may increase feelings of anxiety and depression, specifically in teens and young adults, and the addictive nature of social media activates the brain's reward center by releasing dopamine.
•Key themes related to problematic social media use identified in the literature included a strong link to cyberbullying and symptoms of depression and anxiety.
3.Dose-Response Evidence
•Around 2.5 hours or more of scrolling per day is linked to self-reported depression.
•"It's a damning picture. Social media is harmful for individuals across the lifespan," senior researcher Hans Breiter said.
•In a study of young adults published in JAMA Network Open, those who participated in a one-week social media detox experienced a boost in their mental health, with symptoms of anxiety dropping by 16.1 percent, depression by 24.8 percent, and insomnia by 14.5 percent.
Why the answer is not black-and-white
Not all research finds a strong causal link:
•This past May, the American Psychological Association released a huge, incredibly detailed and nuanced report going through all of the evidence, and finding no causal link between social media and harms to teens.
•There is little evidence that the amount of time young people spend on social media is linked to later mental health issues, according to a new study following more than 3,000 young people found that low to average social media use at ages 11 and 14 did not strongly predict mental ill health three years later.
•A separate 3-year study published in the Journal of Public Health analyzed data from 25,000 students aged 11 to 14 and found no direct causal relationship between social media use and the development of anxiety or depression.
Researchers at Yale Medicine explained that "social media is associated with both benefits and risks for adolescent mental health," and the impact often depends on how teens engage with it, with "problematic use patterns are linked with worse mental health outcomes," especially when teens use social media for long periods or rely on it heavily for validation.
Similarly, findings indicate that social media use is helpful for some intimate relationships and harmful for others based on individual usage and their interaction with their partner via the platform.
Bottom line
•More helpful when used actively to connect, learn, create, and find supportive communities, in moderation, with good sleep and offline relationships intact.
•More harmful when use is heavy (>3 hours/day), passive (scrolling and comparing), occurs early in adolescence, displaces sleep/exercise, or involves cyberbullying and body-image comparison.
The U.S. Surgeon General in June 2024 called for a surgeon general's warning label on social media platforms, reflecting concern, but expert consensus remains: effects are highly individualized.
Healthy-use strategies recommended by APA and others include: limiting time (especially under 3 hours), curating feeds to supportive and educational content, avoiding late-night scrolling, prioritizing in-person interaction, parental monitoring and open conversation, and taking periodic breaks or detoxes.
