For Gen Z, social media is more than a place to share photos or keep up with friends. It is woven into everyday life, from entertainment and friendships to news, identity and self-expression. That constant connection can have benefits, but psychologists and researchers are also examining how it may influence mental health. The picture is more complicated than simply saying social media is ‘good’ or ‘bad’. Research points to factors such as how often young people use these platforms, what they do there, whom they compare themselves with and whether social media interferes with sleep or real-world relationships. These experiences can shape self-esteem and emotional well-being in different ways.
CONSTANT COMPARISON CAN AFFECT SELF-ESTEEM
One of the biggest psychological challenges linked to social media is constant comparison. People often see carefully selected highlights of others’ lives, which can make their own everyday experiences seem less successful or fulfilling. The American Psychological Association has warned that appearance-focused social media use and comparison may be associated with poorer body image, disordered eating and depressive symptoms, particularly among girls. Research by Amy Orben, Adrian Meier, Tim Dalgleish and Sarah-Jayne Blakemore, published in Nature Reviews Psychology in 2024, also explored how social media may contribute to mental-health vulnerability during adolescence. The researchers stressed that the evidence remains mixed and that adolescence is a period of major social, emotional and cognitive development.
A March 2026 study by Alaina Howard and Dr. Marjan Assefi similarly found that social media can have both positive and negative effects on Gen Z, depending on how it is used. Excessive scrolling, FOMO, cyberbullying and unrealistic beauty standards may contribute to anxiety, depression, low self-esteem and body-image concerns. However, social platforms can also provide friendship, support, creativity and mental-health information. The researchers suggest intentional use, reasonable limits and stronger offline connections to promote healthier digital habits. Social media does not affect every young person in the same way. For some, seeing others succeed can inspire them. For others, repeated comparison can reinforce feelings of inadequacy.
ENDLESS SCROLLING CAN AFFECT WELL-BEING AND SLEEP
Live Events
Another concern is the amount of time spent scrolling. A 2026 longitudinal study of 2,350 adolescents in London, led by researchers examining the SCAMP cohort, found that using social-networking sites for more than three hours a day was associated with higher levels of depressive and anxiety symptoms later in adolescence. The researchers also found that insufficient sleep partly explained some of these associations. Earlier research by Jean Twenge, Gabrielle Martin and W. Keith Campbell, published in Emotion in 2018, analyzed data from more than 1.1 million US adolescents. They found that psychological well-being declined after 2012 and that heavier electronic communication and screen use were associated with lower well-being. However, researchers caution against assuming that screen time alone causes mental-health problems.
THE RELATIONSHIP IS MORE COMPLICATED THAN SCREEN TIMEA major theme in modern research is that correlation does not automatically mean causation. In a large 2019 analysis, Amy Orben and Andrew Przybylski examined data from 355,358 adolescents and found that the relationship between digital technology use and well-being was much smaller than some earlier research suggested. Their work highlighted how different analytical methods can produce different conclusions. More recent research reinforces that complexity. A 2025 study led by Luisa Fassi, Amanda Ferguson, Andrew Przybylski, Tamsin Ford and Amy Orben examined social-media use among adolescents with and without mental-health conditions, reflecting growing interest in understanding which young people may be more vulnerable rather than treating all users alike. The takeaway is not that Gen Z should abandon social media. Instead, psychology suggests paying attention to patterns of use. A feed that encourages connection, creativity and support can be very different from one dominated by comparison, negativity or pressure.
Social media is now part of the environment in which Gen Z develops friendships, identity and self-esteem. Its psychological effects depend on much more than the number of minutes spent online. Comparison, appearance-focused content, problematic use, sleep disruption and online pressure can create challenges, while genuine social connection can provide benefits. The research remains mixed, and scientists continue to study cause and effect. For young people, the goal may not be eliminating social media but learning to use it more intentionally. Recognizing when scrolling leaves someone feeling anxious, inadequate or exhausted can be an important first step toward building a healthier relationship with the digital world.
