Doomscrolling and Mental Health: What Psychology Research Shows

Introduction

Have you ever picked up your phone to quickly check the news, only to realise an hour has passed and you feel more anxious than before? If so, you’re not alone. Millions of people engage in what psychologists now call doomscrolling—the habit of continuously consuming negative news and distressing social media content, even when it leaves them feeling worse. Our brains are naturally drawn to potential threats. This tendency once helped humans survive dangerous environments. Today, however, endless access to negative information means that our brains rarely get a chance to switch off. Instead of feeling informed, many people end up feeling overwhelmed, emotionally exhausted and increasingly anxious. Understanding why doomscrolling happens can help us break the cycle. Psychology research is beginning to reveal how excessive exposure to negative online content affects our thoughts, emotions, sleep, relationships and overall mental health.

What Is Doomscrolling?

Doomscrolling refers to the repetitive habit of consuming negative or distressing online information for extended periods, particularly through social media, news websites, or mobile apps. Unlike simply keeping up with current events, doomscrolling often becomes compulsive and it affects mental health. People continue scrolling despite recognising that the content is making them feel stressed or upset. Psychologists believe this behaviour is driven by several psychological processes working together. These include our brain’s negativity bias, fear of uncertainty, reward learning and the desire to regain a sense of control during uncertain situations. Although the term became widely known during the COVID-19 pandemic, research suggests it has become an increasingly common behaviour in modern digital life.

Why Our Brains Are Wired to Keep Scrolling

From an evolutionary perspective, paying attention to threats helped humans survive. Missing important danger could have life-threatening consequences, whereas paying too much attention to potential risks was usually less costly. This is known as the negativity bias. Research continues to show that negative information captures attention more quickly than positive information and remains in memory for longer (Vaish et al., 2008). Social media algorithms unintentionally amplify this tendency by prioritising emotionally engaging content, which often includes conflict, disasters, or alarming headlines. Each swipe promises new information. Occasionally finding something important creates an unpredictable reward schedule similar to those seen in gambling behaviours. Psychology research shows that unpredictable rewards strengthen repetitive habits, making it harder to stop scrolling.

How Chronic Stress Changes the Brain

To understand how stress influences personality, it is helpful to understand what happens in the brain. When we experience stress, the hypothalamic-pituitary-adrenal (HPA) axis releases stress hormones, including cortisol. These hormones are useful in short bursts. They prepare the body to respond to challenges. However, chronic exposure to elevated cortisol levels can affect key brain regions.

The Psychology Behind Doomscrolling

Several psychological mechanisms explain why doomscrolling becomes so difficult to resist.

1. The Need for Certainty

Humans naturally seek information when faced with uncertainty. During periods of crisis, such as pandemics, wars, financial instability, or natural disasters, many people believe that gathering more information will help them feel prepared. Ironically, constantly consuming distressing news often increases uncertainty rather than reducing it. Research suggests intolerance of uncertainty is closely associated with anxiety and repetitive checking behaviours (Carleton, 2016).

2. Fear of Missing Important Information

Many people worry that stopping their news consumption means they may miss something important. This “just one more article” mindset keeps the scrolling cycle going. Unfortunately, most additional information offers little practical benefit while increasing emotional distress.

3. Emotional Reinforcement

Negative news often triggers strong emotional reactions. High emotional intensity increases attention and memory, making it more likely that people will continue engaging with similar content. Social media platforms are designed to maximise engagement rather than emotional wellbeing, meaning emotionally charged posts often receive greater visibility.

What Research Says About Doomscrolling and Mental Health

A growing body of psychology research suggests that frequent doomscrolling is associated with poorer mental health outcomes.

Increased Anxiety

One of the strongest findings involves anxiety. Repeated exposure to threatening information activates the body’s stress response. Over time, this may keep the nervous system in a prolonged state of alertness. Bendau and colleagues (2021) found that excessive COVID-19-related media consumption was associated with higher levels of anxiety, depression, and fear. The more frequently participants checked negative news, the greater their psychological distress.

Depression and Low Mood

Doomscrolling does not simply increase worry. It may also contribute to feelings of helplessness, hopelessness, and emotional exhaustion. When people repeatedly encounter stories about disasters, violence, conflict, and suffering, they may begin viewing the world as overwhelmingly dangerous. This distorted perception can reinforce negative thinking patterns commonly associated with depression.

Higher Stress Levels

Every alarming headline activates the body’s stress response. While a single news article may have little impact, hundreds of emotionally intense posts throughout the day create repeated stress activation. Over time, chronic activation of the stress response can affect concentration, sleep quality, emotional regulation, and overall mental health (McEwen & Akil, 2020).

Poorer Sleep

Many people doomscroll late at night. Research consistently shows that evening screen use is associated with poorer sleep quality, longer time to fall asleep, and increased insomnia symptoms (Scott et al., 2019). Poor sleep then increases emotional reactivity the following day, making people more vulnerable to anxiety and further doomscrolling. This creates another self-perpetuating cycle.

How Doomscrolling Affects the Brain

Modern neuroimaging studies suggest repeated exposure to threatening information influences brain systems involved in attention, emotion and decision-making. The amygdala becomes increasingly sensitive to perceived threats, making individuals more likely to notice negative information. Meanwhile, chronic stress reduces the efficiency of the prefrontal cortex, the area responsible for rational thinking, emotional regulation and impulse control. This combination makes it harder to disengage from distressing content even when people recognise it is affecting their wellbeing.

Signs Doomscrolling May Be Affecting Your Mental Health

Many people underestimate how much their online habits influence their emotional wellbeing. Some warning signs include:

1. Feeling anxious after checking social media or the news.
2. Finding it difficult to stop scrolling despite wanting to.
3. Constantly expecting bad news.
4. Struggling to concentrate during the day.
5. Sleeping poorly after evening screen use.
6. Feeling emotionally exhausted or overwhelmed.
7. Becoming more pessimistic about the future.
8. Losing interest in hobbies or social activities.

Recognising these signs early allows people to make changes before the behaviour becomes deeply ingrained.

Breaking the Doomscrolling Cycle

Fortunately, psychology research suggests several practical strategies can reduce doomscrolling while supporting better mental health.

1. Set Specific Times for News Consumption

Instead of checking updates throughout the day, choose one or two scheduled times. This helps prevent constant stress activation while still allowing you to stay informed.

2. Curate Your Digital Environment

Unfollow accounts that consistently increase anxiety. Instead, follow evidence-based sources, educational pages and content that promotes balance rather than fear. Small changes to your online environment can significantly influence your daily emotional experience.

3. Notice Your Emotional State Before You Scroll

Ask yourself:

“Am I looking for useful information, or am I trying to reduce uncertainty?”

Simply recognising your motivation often reduces automatic scrolling.

4. Replace Scrolling With Grounding Activities

When you notice the urge to continue scrolling, gently redirect your attention. Activities such as walking, stretching, mindfulness, reading, or talking to someone can help regulate the nervous system more effectively than consuming additional news.

5. Protect Your Evenings

Try avoiding distressing news at least one hour before bedtime. Replacing late-night scrolling with relaxing routines supports better sleep and emotional recovery.

Can Doomscrolling Ever Be Helpful?

Staying informed is important. The goal is not to avoid news entirely but to consume information intentionally rather than compulsively. Psychologists describe healthy information seeking as purposeful and time-limited. Doomscrolling, by contrast, continues long after useful information has been gathered.

A useful question to ask yourself is:

“Is this information helping me solve a problem, or is it simply increasing my anxiety?”

If the answer is the second, it may be time to put the phone down.

What Psychology Research Really Shows

Current psychology research suggests doomscrolling is more than a harmless habit. It reflects the interaction between our brain’s natural threat detection systems, digital technology, and emotional regulation. While our brains evolved to notice danger, today’s constant stream of negative information keeps those systems activated for much longer than they were designed to be. Research consistently links excessive exposure to distressing online content with increased anxiety, stress, poor sleep, lower wellbeing, and symptoms of depression. The encouraging news is that small behavioural changes can significantly reduce these effects and improve mental health.

Conclusion

Doomscrolling may feel like a way of staying informed, but psychology suggests it often has the opposite effect. Instead of creating certainty, it fuels anxiety, keeps the nervous system activated, and makes it harder to emotionally recover from daily stress. Fortunately, awareness is the first step toward change. By setting healthier boundaries with digital media, becoming more intentional about when and why we consume information, and making space for genuine recovery, we can protect both our mental health and our emotional wellbeing. Staying informed is valuable, but maintaining psychological balance is just as important.
