The impact of social media on teenagers: the study that reveals what they're really missing
A large British study shows that early use of social media alters fundamental pillars of youth well-being: sleep, self-image, and trust in others. Among Generation Z girls, the effects are more intense, increasing anxiety, distrust, and depressive symptoms throughout adolescence.
Social media is part of the routine of children and adolescents, but its impacts go beyond entertainment. A new study conducted in the United Kingdom reveals that prolonged exposure from a very young age can profoundly affect emotional, social, and psychological development. The effect is especially strong among Generation Z girls, who show greater vulnerability to comparisons, aesthetic pressure, and negative online interactions. The research reveals how these platforms shape behaviors and perceptions at a critical stage of life.
Three Mechanisms That Are Reshaping Adolescence...The research, published in the journal Social Psychiatry and Psychiatric Epidemiology, followed nearly 19,000 British children from birth. The objective was to analyze how the use of social media from the age of 11 influenced mental health between the ages of 11 and 17.
The results identified three central mechanisms:
-delayed bedtime and poorer sleep quality,
-more negative body image,
-increased distrust of others.
These factors mediated the relationship between early exposure and a higher risk of psychological problems in late adolescence.
The decline in trust: the most profound impact among girls
The most striking finding was the emergence of interpersonal distrust—especially among female adolescents.
According to researcher Dimitris Tsomokos, girls who started using social media very young showed, years later, greater difficulty trusting other people.
The reasons include:
-constant social comparisons,
-exclusions in digital groups,
-episodes of cyberbullying.
Since girls tend to depend more on supportive and reciprocal relationships, the emotional insecurity amplified by the platforms increases vulnerability to anxiety and depression. The effects were significantly greater in girls than in boys.
Sleep and self-image: silent but profound consequences...The study showed that early exposure to social media is linked to shorter nights and later bedtimes.
Sleep deprivation impairs:
-emotional regulation,
-school performance,
-mood stability.
Negative self-image arises from comparisons with unrealistic standards: idealized bodies, filters, artificial poses, and “perfect” lives. These constant stimuli fuel insecurity and low self-esteem, critical factors in the emergence of depressive symptoms.
Important: these effects persisted even after socioeconomic adjustments, family history, and pre-existing mental health conditions, reinforcing the robustness of the conclusions.
What Families and Public Policies Can Do
Experts recommend strategies focused on:
-strengthening confidence and social skills,
-promoting healthy sleep routines,
-encouraging a more realistic body image,
-offering digital education for conscious use,
-regulating algorithms, and expanding emotional support in schools.
The study's final message is clear: social media is not neutral in childhood and pre-adolescence. Helping young people—especially girls—navigate this environment in a balanced way is essential to protecting their emotional health.
Social media has a complex and varied impact on teenagers, offering both significant benefits, such as social support and identity exploration, and notable harms, including increased risks of anxiety, depression, and cyberbullying. The effects largely depend on how and how much it is used.
Negative Impacts
-Mental Health Issues: Excessive social media use is strongly linked to higher rates of anxiety and depression. Teens who spend more than three hours a day on these platforms face double the risk of mental health problems.
-Poor Body Image and Self-Esteem: Platforms filled with curated and filtered images often lead to social comparison, making nearly half of adolescents feel worse about their own bodies and lives. This is associated with higher rates of body dysmorphic disorder and disordered eating behaviors.
-Cyberbullying: Social media facilitates anonymous and persistent harassment, which can cause severe psychological distress, self-harm ideation, and social isolation.
-Sleep Disruption: The psychological arousal from constant engagement and the blue light from screens can disrupt sleep patterns and circadian rhythms, which in turn worsens mood and cognitive function.
-Academic Performance: The constant stream of notifications can be a major distraction, interfering with homework, focus, and time management skills.
-Fear of Missing Out (FOMO): The curated highlights of peers' lives can intensify feelings of loneliness, isolation, and the pressure to be constantly available online, leading to a compulsive need to check feeds.
-Reduced In-Person Social Skills: Heavy reliance on digital communication can make in-person interactions feel awkward or anxiety-inducing, as teens miss opportunities to practice important nonverbal communication skills (e.g., body language, facial expressions).
-Addiction and Compulsive Behavior: The brain's reward system (dopamine pathways) is highly sensitive during adolescence. Features like "likes" and notifications can trigger a feedback loop similar to addiction, making it hard to limit use.
Positive Impacts
-Social Connection and Support: Social media allows teens to stay connected with friends and family and build social networks, which can be especially beneficial for those who lack offline support or belong to marginalized groups (e.g., LGBTQ+ youth).
-Identity Exploration and Self-Expression: Platforms offer a space for self-expression and exploring different facets of identity (opinions, beliefs, interests), which can lead to a clearer sense of self and increased well-being.
-Access to Information and Educational Opportunities: Teens can access valuable information, learn about current events, find educational resources, and connect with experts in their fields of interest.
-Empowerment and Civic Engagement: Social media enables youth to engage in activism, raise awareness for causes they care about, and feel empowered to have their voices heard.
Guidance for Healthy Use...Experts recommend a balanced approach that includes parental monitoring, promoting digital literacy, setting clear boundaries (e.g., no phones in the bedroom at night), encouraging in-person interactions and physical activities, and having open conversations about online experiences.
