Social media has become an integral part of teenage life in recent years. Platforms like Instagram, Snapchat, TikTok and Facebook allow youth to connect with friends, share photos and videos, learn about current events and popular culture trends. Many studies have begun to investigate if excessive social media use may have unintended negative consequences on mental health and well-being among adolescents. This paper aims to analyze and discuss the existing literature on how social media impacts teenage psychological health and development.
Social networking sites provide new and engaging ways for teenagers to socialize and spend their free time. According to survey data, approximately 95% of teens ages 13-17 report using at least one social media platform regularly (Pew Research Center, 2018). The appeal of social media lies in its ability to facilitate communication and connection with peers. Teenagers face immense pressure to fit in and gain acceptance from their peers during this developmental period. Social media satisfies the powerful human need for social belonging and relationships (Maslow, 1943). It grants near-constant access to friends through messaging, commenting and reacting to posts. Additionally, cultivating an idealized online image and curating a compelling profile allows teens to project a certain image of themselves that they wish to portray (Manago et al., 2008).
Psychologists also argue that social comparison and perfectionism in the realm of social media may lead to increased anxiety, depression, loneliness and diminished self-esteem in some adolescents (Frison & Eggermont, 2016). Multiple platform updates per day expose teenagers endlessly to highly curated snippets portraying the seemingly perfect lives of their peers (Fardouly & Vartanian, 2015). Subconscious social comparisons are difficult to avoid, and comparing one’s unedited everyday life to idealized snapshots shared by others risks triggering feelings of inadequacy or inferiority (Vogel et al., 2014). Further, the intense desire for popularity and likes on posts can motivate attention-seeking behaviors. Teenagers chasing validation and an artificial sense of importance awarded by superficial measures of engagement like likes, comments and follower counts on their profiles subjects them to performance pressures that negatively impact mental health over time (Sherlock & Wagstaff, 2019).
In addition to the psychosocial risks posed, heavy social media usage disrupts normal teenage development of identity formation and real-world social skills. Adolescence represents a key transitional period where youth refine their self-concepts and sense of belonging through social interactions and experimentation prior to entering adulthood (Erickson, 1968). Limitless virtual social networking risks replacing meaningful in-person communication upon which teenagers build confidence and hone emotional intelligence (Turkle, 2011). The cognitive engagement demanded by conversations, bonding experiences, and challenges of real social settings provide scaffolding essential for personality development (Subrahmanyam & Šmahel, 2011). Constant connectivity further incentivizes avoidance of discomfort, leading to the minimization of risks and emotional challenges teens should face to foster resilience as they grow into well-adjusted young adults (Sherman et al., 2016).
Furthermore, disturbed sleep patterns represent a biological risk associated with late-night social media use. Exposure to blue light emitted by screens suppresses natural melatonin production involved in preparing the body for rest (Cain & Gradisar, 2010). Even brief periods of technology use close to bedtime delay sleep onset and reduce sleep duration and quality (Lemola et al., 2015; Thompson & Olatunji, 2020). Chronically curtailed sleep deprives the developing brain of much-needed restorative processes shown to support memory consolidation, emotional regulation, and decision-making abilities integral to the challenges of adolescence (Dworak et al., 2007). Additionally, sleep insufficiency predicts the onset and severity of mental health disorders in youth such as anxiety and depression (Johnson et al., 2006; Wong et al., 2009).
Existing theoretical frameworks and research findings suggest excessive social media engagement poses multidimensional risks to teenage well-being. While technologies offer engagement and connection critical to adolescence, unfettered access risks normal healthy development by incentivizing social comparison, superficial validation-seeking, stunted social skills growth, disrupted identity formation processes and disturbed circadian rhythms. The following sections will further analyze several peer-reviewed studies exploring specific relationships between social media metrics and indicators of adolescent mental health such as self-esteem, depression, and loneliness. Limitations and directions for future research will also be discussed to provide additional context around this important and rapidly evolving issue.
