The scroll begins innocuously. Just checking notifications before bed. But twenty minutes later, the phone still glows, thumb still flicking upward, brain still processing an endless stream of updates, photos, opinions, advertisements. Finally, the screen goes dark. Sleep should come easily after a long day, but instead, restlessness settles in. Mood has shifted—not dramatically, but noticeably. The energy before scrolling felt neutral, maybe slightly tired. The energy after feels depleted, anxious, vaguely inadequate.
This pattern repeats daily for billions of people. Research published in 2025 examining Romanian adults found that over 5.17 billion users accessed social media in 2024, with projections reaching 6.05 billion users in 2028. Among 217 participants, the study revealed that social network addiction significantly impacts mental health, with manifestations of anxiety and depression symptoms mediated by self-esteem and influenced by factors including age and professional status.
What makes this phenomenon particularly insidious is that social media doesn’t necessarily feel harmful while it’s happening. The scroll provides temporary escape, brief entertainment, moments of connection. The negative effects accumulate subtly, manifesting as mood changes, anxiety spikes, and diminished wellbeing that people struggle to attribute to their digital consumption.
A 2025 study from UT Southwestern Medical Center examining 489 patients ages 8 to 20 receiving treatment for depression, suicidal ideation, or suicidal behaviors found that 40% reported problematic social media use—defined as being upset or experiencing discontent when not using social media. These individuals reported higher rates of screen time, more and higher depressive symptoms, increased anxiety, elevated suicidal thoughts, and poorer overall wellbeing.
Understanding why social media consistently worsens mood requires examining the specific psychological and neurobiological mechanisms at play.
The Neuroscience of Digital Deterioration
Before examining specific reasons social media undermines wellbeing, understanding how platforms interact with brain chemistry provides essential context. Research on dopamine and social media explains that every time notifications arrive—likes, comments, shares—the brain releases dopamine, the same “reward” chemical involved in pleasure, motivation, and attention.
Neuroscience analysis published in 2024 notes that social media platforms are designed to exploit the brain’s natural reward system by offering unpredictable rewards in the form of likes or messages, functioning similarly to mechanisms behind gambling addiction. This creates what researchers call “intermittent reinforcement”—never knowing when the next like will arrive or when a post might go viral makes the reward even more exciting to the brain, leading to compulsive checking behavior.
A 2024 study revealed that the average user makes 300 distinct scrolling actions per day, with each action potentially triggering a dopamine response. Over time, users develop tolerance, requiring more engagement to achieve the same dopamine rush, leading to increased usage and potential addiction.
This neurobiological foundation creates vulnerability to specific mechanisms that reliably worsen mood.
The 5 Mechanisms That Undermine Wellbeing
1. Constant Upward Comparison Creates Perpetual Inadequacy
Every post someone sees represents a curated highlight—the best angle, the most flattering moment, the carefully edited victory. Yet the brain processes these highlights as representative samples of others’ entire lives, creating systematic upward comparison that inevitably produces feelings of inadequacy.
Research published in 2025 in Frontiers in Psychology examining 314 participants found that the highly curated and idealized content prevalent on social networking sites encourages users to engage in upward social comparisons, where they compare themselves to seemingly superior others. Studies consistently show that frequent social networking site use is linked to increased upward comparisons, which mediated the association between Instagram use and lower global self-esteem.
The research noted that 72% of Americans use social media, rising to 84% among 18-29-year-olds. Instagram alone has over 2.3 billion active users, Facebook has surpassed 2.9 billion, and TikTok has reached over 1 billion monthly active users. Each platform provides endless comparison opportunities.
A 2024 systematic review examining nine studies found simple correlations between social comparison on social networking sites, envy, and depression. Three cross-sectional studies successfully tested models with envy as mediator between social networking site use and depression, demonstrating that comparison doesn’t just correlate with worse outcomes—it actively causes them through psychological mechanisms like envy.
The comparison overload becomes particularly damaging because it’s relentless. Unlike pre-digital eras where people occasionally compared themselves to neighbors or colleagues during in-person interactions, social media provides continuous comparison streams. Every scroll presents new opportunities to measure personal lives against others’ curated victories, creating accumulating deficits in self-perception.
Research on Instagram use among British adolescents found that benign envy positively mediated the relationship between social comparison and inspiration, while malicious envy worked in the opposite direction. The study emphasized that comparing to similar others elicited more benign and less malicious envy, suggesting that social comparisons may be more inspiring when people compare themselves to similar others rather than unachievable false role models.
However, the volume of comparison opportunities overwhelms any potential benefits. Even when individual comparisons might inspire rather than demoralize, the sheer quantity creates cumulative damage to self-esteem and mood.
2. FOMO Triggers Anxiety That Pervades Daily Life
Fear of Missing Out—FOMO—represents one of social media’s most documented psychological impacts. Research from the University of Texas at Dallas explains that FOMO doesn’t stem from physical threat but from perceived social threat, feeling just as real to the brain. Psychologically, FOMO can manifest briefly, become a long-term mindset, or create deeper feelings of social inferiority or loneliness.
A 2024 study found that 69% of social media users experience FOMO—a legitimate psychological condition that triggers what psychologists call “social exclusion anxiety,” creating powerful drives to stay constantly connected. The digital age has amplified this ancient survival instinct, transforming it into modern-day social media compulsion.
According to the “Digital 2024” report, FOMO is most commonly experienced by people aged 15-19 years, with 94% experiencing medium or high levels. The fear of being bypassed by something is strongly linked to being on social media. Studies show that highly sophisticated FOMO sufferers often weave time browsing social media into other activities, starting and ending the day with it, eating while using smartphones, making social media browsing part of daily routines that entail needing to satisfy information needs resulting from fear of bypassing or disconnecting.
Research published in 2024 examining 256 Italian university students found that Fear of Missing Out influenced problematic social media use through the serial mediating role of social comparison and self-esteem. The study revealed that FOMO doesn’t necessarily have direct influence on problematic social media use but appears to act serially through social comparison and individuals’ self-esteem.
The neurobiological pathway involves the dopaminergic reward system, including the mesolimbic pathway, which releases dopamine involved in pleasure, motivation, and attention. Social media platforms exploit this system by offering unpredictable rewards in the form of likes or messages. Over time, this conditioning leads to compulsive behaviors, drawing users back into cycles of scrolling and comparing. That sense of wanting more, combined with fear of missing something fun, helps FOMO thrive.
A 2025 cross-sectional and quasi-experimental study involving 470 Saudi students found positive correlation between fear of missing out and social media addiction, demonstrating that FOMO not only worsens mood directly but also drives increased usage that compounds negative effects.
3. Dopamine-Driven Feedback Loops Create Dependency and Crashes
Social media platforms are deliberately engineered to maximize engagement through exploitation of the brain’s reward systems. Research on dopamine mechanisms explains that the brain’s reward system responds to likes, comments, and shares by releasing small bursts of dopamine with each interaction. This neurochemical response reinforces the behavior, making social media use habit-forming and potentially addictive.
The constant stream of novel content and unpredictable rewards mimics mechanisms of gambling, activating the same neural pathways. Understanding this dopamine-driven cycle is crucial because while platforms offer benefits, their ability to hijack the brain’s reward system leads to excessive screen time and negative impacts on mental health.
Neurobiological research notes that when people expect something beneficial or pleasant, dopamine levels in the brain increase, motivating actions that lead to receiving rewards. However, frequent dopamine release under influence of stimuli or actions causes the body to adapt, treating elevated dopamine as the new normal. Every drop from the dopamine peak feels like being thrown out of balance.
In the social media context, each new notification, like, or comment triggers slight increases in dopamine levels, making users want to return to applications to see if another reward is waiting. The average smartphone user checks their device 58 times per day, with each check potentially reinforcing dopamine-driven behavior patterns, making it increasingly difficult to break the scrolling cycle.
Research from 2020 examining FOMO as process addiction noted that it meets certain symptoms including salience of social media, withdrawal symptoms, conflict with other priorities, and mood modification. Compulsive behavior relates to addiction, as addiction represents persistent, compulsive dependence on behavior or substance. In this case, it’s the actual process of doing something that makes individuals addicted.
What makes this particularly damaging to mood is the crash following dopamine spikes. After periods of heavy social media use—with repeated dopamine hits from notifications and engagement—cessation creates dopamine deficit. This manifests as restlessness, irritability, anxiety, and depressed mood, driving users back to platforms seeking relief, perpetuating the cycle.
4. Passive Consumption Amplifies Loneliness and Disconnection
Not all social media use affects wellbeing equally. Research distinguishes between active use (posting, commenting, messaging) and passive use (scrolling, viewing without engaging). Studies consistently find that passive consumption—which constitutes the majority of time spent on platforms—worsens mental health outcomes.
A study cited by the European Commission found that passive social media use is linked to increased feelings of loneliness. One research study found that high usage of Facebook, Snapchat, and Instagram increases rather than decreases feelings of loneliness. Conversely, reducing social media usage can actually make people feel less lonely and isolated and improve overall wellbeing.
The mechanism involves voyeurism without genuine connection. When people scroll through others’ lives without actively engaging, they consume social information without participating in social exchange. This creates illusion of connection while actually deepening isolation—seeing others’ social activities without being part of them highlights exclusion rather than fostering belonging.
Research from PMC examining quantity of social media use found that more frequent visits to social media platforms each week correlated with greater depressive symptoms. More time spent using social media is also associated with greater symptoms of anxiety. The actual number of platforms accessed contributes to risk—among survey respondents using between 7 and 11 different social media platforms compared to respondents using only 2 or fewer platforms, there was 3 times greater odds of having high levels of depressive symptoms and 3.2 times greater odds of having high levels of anxiety symptoms.
The passive consumption trap intensifies during periods when people most need genuine connection. Feeling lonely or depressed often triggers increased social media use seeking connection, but passive scrolling provides counterfeit connection that worsens underlying loneliness, creating vicious cycles where mood deterioration drives behavior that further deteriorates mood.
5. Exposure to Hostility, Comparison, and Negativity Accumulates Psychological Damage
Beyond the platform mechanics and neurobiological mechanisms, the actual content encountered on social media frequently degrades mood through exposure to cyberbullying, hostile comments, negative news, and conflict.
Research examining cyberbullying found that it represents a form of online aggression directed towards specific individuals, perceived as most harmful when compared to random hostile comments. Cyberbullying on social media consistently shows harmful impact on mental health in the form of increased depressive symptoms as well as worsening anxiety symptoms, as evidenced in a review of 36 studies among children and young people.
Furthermore, cyberbullying disproportionately impacts females—a national survey of United States adolescents found females were twice as likely to be victims of cyberbullying compared to males. For youth ages 10 to 17 who reported major depressive symptomatology, there was over 3 times greater odds of facing online harassment in the last year compared to youth who reported mild or no depressive symptoms.
In a 2018 national survey of young people, respondents ages 14 to 22 with moderate to severe depressive symptoms were more likely to have had negative experiences when using social media, and in particular, were more likely to report having faced hostile comments or being “trolled” from others.
Beyond direct harassment, mere exposure to negative content accumulates damage. A 2025 narrative review analyzing research from 2016 to 2024 found that social media use is linked to decrease in mental health, characterized by harmful psychological outcomes and poor mental health. Qualitative studies and literature reviews found correlation between social media use and increases in adolescents’ anxiety, depression, sleep problems, self-harm, and suicide.
A 2025 systematic review and meta-analysis examining correlations between social media addiction and mental health outcomes among students found significant associations between social media addiction and anxiety, depression, FOMO, loneliness, and self-esteem. As of January 2025, there were 5.40 billion internet users, equivalent to 66% of the world’s population, all potentially exposed to these mechanisms.
The cumulative exposure to negativity—whether through hostile interactions, distressing news, or simply witnessing others’ conflicts—creates what researchers call “emotional contagion,” where negative emotional states spread through social networks, affecting observers even when they’re not directly involved in conflicts or crises being witnessed.
The Intervention Evidence
While the mechanisms through which social media worsens mood are well-documented, equally important is evidence that reducing use produces measurable improvements. A 2018 University of Pennsylvania study found that reducing social media use to 30 minutes per day resulted in significant reductions in levels of anxiety, depression, loneliness, sleep problems, and FOMO.
Research published in 2024 confirmed that limiting social media use decreases depression, anxiety, and related symptoms. Even being more mindful of social media use can have beneficial results on mood and focus. While 30 minutes daily may not be realistic for many people—let alone full “social media detox”—reduction in time spent still produces benefits.
A 2025 cross-sectional study examining Saudi students demonstrated statistically significant differences in students’ mean scores for FOMO and social media addiction before and after intervention through guidance and counseling programs, suggesting that targeted interventions can effectively reduce both FOMO and problematic social media use.
These intervention studies demonstrate something crucial: the mood deterioration isn’t inevitable or irreversible. When use decreases, wellbeing improves, confirming that social media directly causes rather than merely correlates with diminished mental health.
The Design Problem
Understanding these mechanisms reveals that mood deterioration isn’t accidental—it’s designed. Research on platform design notes that social media platforms employ teams of behavioral psychologists and UX designers specifically to maximize screen time, with success measured in minutes of attention captured.
Modern social media interfaces employ “friction-removal design,” eliminating natural stopping points through infinite scrolling, autoplay features, and notification systems designed to draw users back repeatedly. The gamification of social interactions through streaks, badges, and follower counts further reinforces addictive patterns.
Smartphones provide constant access to social media, enabling users to seek instant gratification at any time. This accessibility blurs lines between online and offline life, making it nearly impossible to establish healthy boundaries when platforms are designed to be maximally intrusive and compelling.
Research from 2020 examining FoMO reduction methods emphasized that social media can play a part in triggering FOMO and can be designed to provide preventative measures. Solutions must be socio-technical, with design teams being inter-disciplinary, involving members with skills in software engineering, interactive systems, social psychology, and behavioral change.
However, current platform incentives prioritize engagement over wellbeing. The business model depends on maximizing time spent and emotional engagement, creating fundamental misalignment between platform success metrics and user mental health.
Moving Toward Healthier Patterns
Given that complete social media avoidance is unrealistic for most people in modern life, the question becomes how to mitigate harms while maintaining necessary connections and functions.
Clinical recommendations include:
Setting time limits: Use apps to track how much time is spent on social media daily, then set goals for reduction. Even small decreases produce measurable wellbeing improvements.
Eliminating phones from bedrooms: Removing devices from sleeping areas reduces nighttime scrolling that disrupts sleep and creates vulnerability to negative content consumption during periods of reduced emotional regulation.
Scheduling specific check-in times: Rather than responding to every notification immediately, designating specific times for social media checking reduces compulsive use driven by FOMO.
Curating feeds intentionally: Unfollowing accounts that trigger comparison, anxiety, or negative emotions while seeking content that genuinely provides value or connection.
Prioritizing active over passive use: When using social media, actively engaging through comments and direct messages rather than passively scrolling produces better mental health outcomes.
Research recommendations for clinicians emphasize asking patients about specific goals with their usage—if someone is continually scrolling through exercise or fad diet videos, problematic social media use may be attempting to cope with body dysmorphia. If always browsing due to FOMO, the problem may reside in anxiety or self-esteem issues requiring direct treatment.
Encouraging lifestyle interventions—hobbies like sports, hiking, reading books, or journaling—helps keep idle hands busy and readjusts brains to appreciate non-instant gratification. Converting FOMO (fear of missing out) into JOMO (joy of missing out) represents a fundamental mindset shift that supports healthier digital engagement.
The Broader Context
While individual strategies matter, recognizing that social media’s mood-worsening effects stem from deliberate design choices suggests broader societal and regulatory responses may be necessary. The 2025 UT Southwestern study noted that characteristics of problematic use mirror those of addiction: continued use even when wanting to stop, cravings, interference with daily tasks and activities, deceptive use, interpersonal disruptions.
Dr. Betsy Kennard, the study’s lead author, emphasized: “The appropriate amount of social media activity isn’t a ‘one-size-fits-all’ issue, so what is fine for one individual may not be OK for someone else.” This acknowledges individual variability while also highlighting that 40% of depressed and suicidal youth in the study reported problematic use—a prevalence rate suggesting systemic rather than purely individual problems.
Research teams are working to develop and test interventional tools that help young people reduce dependence on social media, including family social media plans where members discuss usage limits and agree to specific guidelines, helping young people better manage screen time before it creates mental health impacts.
The evidence is clear: social media, as currently designed and used, reliably worsens mood for substantial portions of users through well-documented psychological and neurobiological mechanisms. Recognizing these mechanisms allows for informed decisions about usage patterns, conscious mitigation strategies, and advocacy for design changes that prioritize user wellbeing over engagement metrics.
What patterns have been observed in personal relationships with social media? When does use reliably worsen mood, and what changes have produced improvements? How do different platforms affect wellbeing differently? Sharing observations might help others identify patterns worth examining in their own digital consumption.
If this perspective resonates, consider sharing it with someone who might benefit from understanding that feeling worse after social media use isn’t personal weakness—it’s predictable response to platforms designed to maximize engagement through mechanisms that reliably undermine psychological wellbeing.
