QUICK ANSWER
Doomscrolling is the compulsive habit of consuming negative news and content online even when it increases distress. It is driven by negativity bias, a hardwired evolutionary tendency to prioritise threatening information, combined with the infinite scroll design of social media platforms. Understanding this mechanism is the first step toward breaking the cycle without relying on willpower alone.

You tell yourself you will check the news for five minutes. Forty minutes later, you are still reading about disasters, political crises, and public health scares, feeling worse with every article, and yet unable to stop. This is doomscrolling: the act of continuing to consume disturbing or distressing content online despite knowing it is making you feel worse.
The term entered widespread usage during the COVID-19 pandemic, when millions of people found themselves unable to stop refreshing news feeds for updates about case numbers, hospitalisations, and policy changes. But the behaviour itself is not new and did not originate with the pandemic. It is the product of ancient brain circuitry meeting modern platform design, and the combination is remarkably effective at hijacking your attention.
Doomscrolling is not a character flaw or a sign of anxiety disorder, although it can worsen both. It is a predictable psychological response that almost anyone can fall into under the right conditions. Understanding the specific mechanisms driving it gives you tools that willpower alone cannot provide.
The Evolutionary Root: Negativity Bias
The human brain evolved over hundreds of thousands of years in environments where threats were physical, immediate, and often lethal. A brain that paid more attention to potential dangers than to neutral or positive stimuli survived longer than one that did not. This attentional bias toward threat has been documented consistently across species and is one of the most robust findings in all of psychology.
Psychologist Roy Baumeister and colleagues examined the research literature on negativity bias and concluded that bad information, bad events, and bad feedback have stronger and longer-lasting psychological effects than equivalent positive information. A single piece of bad news requires multiple pieces of good news to neutralise its emotional impact. This is not irrationality. It is the cost of a survival mechanism that served human beings well for most of evolutionary history.
The problem is that in a modern information environment, this bias is continuously triggered. News outlets, social media algorithms, and platform notification systems all discovered long ago that negative, threatening, and alarming content generates far more engagement than positive content. Your negativity bias is not protecting you from real threats. It is being exploited by content systems designed to maximise your attention as a commercial resource.
RESEARCH NOTE: Negativity Bias and Information Seeking
A 2020 study published in the journal Health Communication found that during the early months of the COVID-19 pandemic, individuals who scored higher on intolerance of uncertainty spent significantly more time seeking health information online and reported higher anxiety as a result. Crucially, more information did not reduce anxiety. It intensified it. The search for certainty in an uncertain environment creates a loop that the brain cannot escape.
Platform Architecture and the Scroll That Never Ends
Infinite scroll was introduced to social media platforms not as a neutral design feature but as an engagement mechanism. Aza Raskin, who invented the infinite scroll while working at Humanised, later became one of its most prominent critics. He estimated that infinite scroll costs humanity approximately 200,000 additional hours of scrolling per day and has publicly expressed regret about creating it.
Before infinite scroll, web pages had natural stopping points. You reached the bottom and had to actively choose to load more content. This moment of friction was enough to interrupt automatic behaviour and give the conscious mind a chance to reassert control. Infinite scroll removes all friction and creates a seamless, never-ending stream. The decision to keep scrolling is replaced by the decision to stop, which requires far more conscious effort.
Variable reward schedules deepen the effect. Like slot machines, social media feeds deliver unpredictable combinations of interesting, entertaining, alarming, and neutral content. Unpredictable rewards are significantly more compelling than predictable ones, a finding established by behaviourist B.F. Skinner and replicated extensively across gambling research. Your brain keeps scrolling in search of the next emotionally significant piece of content, even as the cumulative effect on your mood becomes increasingly negative.
EXPERIENCE NOTE
Therapists working with clients on screen time and anxiety frequently report the same pattern: clients describe doomscrolling as feeling like scratching an itch that never goes away. The more you scratch, the worse the itch becomes. The information provides momentary relief from uncertainty but amplifies the underlying anxiety almost immediately. Recognising this loop while inside it is difficult because the brain experiences the next scroll as potentially providing the resolution the previous one did not.
What Doomscrolling Does to Your Brain and Body
Sustained doomscrolling activates the brain’s threat detection systems. The amygdala, the brain region most directly involved in processing fear and threat, does not distinguish between a predator approaching your campfire and an article about a distant catastrophe. Both register as threat-relevant information and trigger physiological stress responses, including cortisol release, elevated heart rate, and increased muscle tension.
Psychologist Mary McNaughton-Cassill’s research on news consumption and psychological health found that heavy news consumption was consistently associated with higher stress, anxiety, and feelings of powerlessness. The sense of powerlessness is particularly important: consuming large amounts of information about events you cannot influence or control produces what psychologist Martin Seligman identified as a pattern resembling learned helplessness.
Sleep disruption is a consistent downstream effect. Doomscrolling before bed exposes you to threatening and emotionally activating content during the period when the nervous system most needs to downregulate. Research by the National Sleep Foundation found that people who used phones in the hour before sleep reported significantly worse sleep quality than those who did not, with the content type mattering as much as the screen exposure itself.
RESEARCH NOTE: Doomscrolling and Psychological Wellbeing
A 2022 study by Sharma and Oliver published in Health Psychology found that problematic news consumption, defined as news-checking that felt compulsive and distressing rather than informative, was significantly associated with stress, anxiety, and physical health symptoms, including headaches and fatigue. Notably, the amount of news consumed mattered less than the compulsive quality of the consumption. Checking once and stopping had very different effects from checking repeatedly without satisfying the urge.
Breaking the Doomscrolling Loop
The most important insight from the research is that more information does not resolve the anxiety that drives doomscrolling. The brain is seeking certainty in an environment that cannot provide it. Every article that answers one question generates two more. The loop is self-reinforcing by design, and the only way out is structural change rather than stronger willpower.
Researcher Dr. Tara Swart, a neuroscientist and author, recommends what she calls a news diet rather than a news fast: deciding in advance when and how long you will engage with news, limiting it to specific times of day, and avoiding it entirely in the first and last hour of the day. This structural boundary works better than resolutions to simply scroll less, because it removes the moment-to-moment decision from a fatigued executive function system.
Behavioural substitution is more effective than simple suppression. When you feel the urge to doomscroll, replacing the behaviour with a predetermined alternative, a three-minute breathing exercise, a short walk, or even a different category of content, interrupts the automatic loop without relying on resisting the urge directly. Psychologist Wendy Wood’s research on habit formation shows that behaviours are most effectively changed through environmental redesign rather than motivational effort.
KEY TAKEAWAY
- Doomscrolling is driven by negativity bias meeting infinite scroll architecture.
- Your brain is not broken. It is doing exactly what it evolved to do in an environment specifically designed to exploit that tendency.
- Breaking the loop requires structural changes to your information environment, not stronger willpower.
- Time limits, designated news windows, and phone-free zones are more effective than resolutions to simply stop.
Frequently Asked Questions
Is doomscrolling a form of anxiety?
Doomscrolling is not a clinical diagnosis, but it is closely linked to anxiety, particularly health anxiety and generalised anxiety disorder. For people with anxiety, doomscrolling functions as a compulsive information-seeking behaviour aimed at reducing uncertainty, but it reliably increases distress rather than reducing it. It mirrors the compulsive checking behaviours seen in OCD without necessarily meeting clinical thresholds.
Why does doomscrolling feel impossible to stop at the moment?
Because stopping requires the executive function system to override an automatic behaviour that is being maintained by both internal reinforcement (temporary anxiety reduction) and external design features (infinite scroll, variable rewards). Both of these are powerful drivers of automatic behaviour. At the moment, the prefrontal cortex is at a disadvantage against the combined force of habit, emotion, and design.
Does everyone doomscroll?
Research suggests most people engage in some version of compulsive negative content consumption, but the degree varies significantly. People with higher intolerance of uncertainty, pre-existing anxiety, and those going through particularly uncertain life periods are most susceptible. The 2020 to 2022 period saw a widespread increase across most demographic groups during the pandemic.
Can doomscrolling cause depression?
Prolonged doomscrolling is associated with depressive symptoms, including hopelessness, helplessness, and low mood. The mechanism likely involves both the direct effects of sustained threat activation on mood and the opportunity cost of replacing potentially restorative or meaningful activities with distressing content consumption. For already-vulnerable individuals, heavy doomscrolling can contribute meaningfully to depressive episodes.
What is the best time of day to check the news if you must?
Research and clinical guidance converge on mid-morning as the least harmful time window, after the cortisol awakening response has passed and before the evening wind-down period. The worst times are first thing in the morning, which sets a threat-activated tone for the day, and within an hour of sleep, which disrupts the nervous system’s downregulation.
