in-depth: Why Missile Alerts and War Updates Trigger Doomscrolling

When missiles illuminated the Persian Gulf and explosions rocked the region this past weekend, millions instinctively reached for their smartphones. In the wake of US-Israel attacks in Iran earlier in the week, social media feeds rapidly became a torrent of breaking news, videos, and speculative updates, drawing users into a compulsive cycle known as "doomscrolling." This pervasive digital behavior transforms a quick search for information into an endless stream of crisis coverage, fueled by algorithms designed for engagement.

Understanding Doomscrolling

Doomscrolling is characterized as the repetitive consumption of negative or crisis-related information. Unlike "dopamine scrolling," which seeks stimulation, doomscrolling is primarily about remaining fixated on threat-related material, as defined by Alexander TR Sharpe, an associate lecturer at the University of Chichester. A brief check for updates on escalating international tensions or cyber incidents can quickly devolve into an unceasing loop of war reports, political instability, and misinformation.

Within minutes of new developments, videos of missile interceptions, airspace closures, and cyber incidents — alongside significant misinformation — circulate online. With confirmed information often emerging slowly but updates arriving constantly, many users find themselves endlessly refreshing feeds, attempting to piece together events in real time.

The Evolutionary Imperative to Engage

This compelling urge to consume bad news is not accidental, according to cognitive scientists. Humans are fundamentally wired to prioritize threats as a survival mechanism, an evolutionary pressure that has shaped our cognitive systems. Media psychology researcher Reza Shabahang explains that human memory is particularly effective at encoding and retaining negative news, making such information notably salient and enduring.

This innate bias means that during moments of international crisis, our brains are predisposed to seek out and fixate on potential dangers. What feels like a responsible attempt to stay informed quickly becomes a potent feedback loop between our brain's threat-detection system and the platforms meticulously engineered to maximize user engagement.

The Toll of Constant Crisis: Mental Health Impacts

Sustained doomscrolling extends beyond simple engagement, often significantly impacting mental well-being. A 2026 study by Sharpe identified links between frequent doomscrolling and rumination, emotional exhaustion, and an intolerance of uncertainty. Participants who reported this behavior also exhibited higher levels of anxiety, depression, and stress, coupled with reduced resilience.

Shabahang points out that this continuous exposure to unsettling reports and images can resemble a form of indirect trauma. While not always leading to full-blown trauma, it can elicit acute stress responses and, in some instances, symptoms associated with post-traumatic stress. The result is often a nervous system that struggles to return to a state of calm, perpetually on alert.

The Amygdala's Loop: Why We Can't Stop Refreshing

Our brains are driven to resolve uncertainty, a powerful motivator that can lead people to tolerate physical discomfort in experiments. During a crisis, refreshing a news feed or social media platform can feel like a protective action, a necessary step to grasp unfolding events. However, this constant pursuit of information without clear resolution can be detrimental.

A 2024 report by Shabahang found that prolonged exposure to negative news correlates with increased anxiety, heightened insecurity, and maladaptive stress responses. Learning research suggests that when emotional activation lacks closure, it tends to strengthen stress responses rather than diminish them. Hamad Almheiri, founder of BrainScroller, aptly describes this effect: “The amygdala remains sensitized. Even without physical danger, the brain responds as if risk is ongoing.” While some nuance is needed regarding direct neuroscientific biomarkers, Sharpe confirms consistent links to hypervigilance, rumination, and difficulty tolerating uncertainty.

Engineered Engagement: How Social Platforms Optimize for the Scroll

Doomscrolling does not occur in a vacuum; it thrives within social media environments specifically designed for maximum user engagement. At a behavioral level, the mechanics of scrolling often mirror that of a slot machine: unpredictability. Each swipe or refresh presents the potential for something new—a breaking headline, a critical update, or a shocking video.

This inherent uncertainty is a key factor in keeping users perpetually hooked, prompting them to check their feeds repeatedly. The rapid circulation of videos depicting missile interceptions, airspace closures, and cyber incidents—often mixed with misinformation—further intensifies this cycle. The interplay between confirmed information emerging slowly and updates arriving constantly compels users to endlessly refresh, attempting to piece together events in real time.

Navigating the Digital Deluge

The recent surge in global tensions underscores the complex interplay between human psychological wiring and the sophisticated engineering of digital platforms. What begins as a natural human instinct to monitor threats can quickly escalate into a pervasive and potentially harmful pattern of doomscrolling. Understanding these underlying mechanisms is crucial for individuals navigating the constant flow of crisis information and for technologists designing the digital spaces we inhabit.

FAQ

Q: What is doomscrolling?

A: Doomscrolling refers to the compulsive and repetitive consumption of negative or crisis-related information, such as war updates, political instability, or cyberattack reports, typically delivered through endless updates on social media and news feeds. It is distinct from other forms of scrolling by its focus on threat-related material rather than mere stimulation.

Q: Why do humans tend to doomscroll, especially during crises?

A: Humans are evolutionarily wired to prioritize threats for survival. Our cognitive system is biased towards encoding and retaining information related to danger and emergencies, making negative news particularly salient and difficult to ignore. Social media platforms also exploit this by designing feeds that keep users engaged through unpredictable updates, similar to a slot machine.

Q: What are the potential negative effects of doomscrolling?

A: Frequent doomscrolling has been linked to increased anxiety, depression, stress, rumination, emotional exhaustion, and a lower resilience. It can also resemble indirect trauma exposure, leading to acute stress responses and a nervous system that struggles to return to a state of calm. Prolonged exposure to negative news without resolution can strengthen maladaptive stress responses.
