Most people who doomscroll already suspect it is not good for them. What is less clear is how bad it actually is, why it is so hard to stop, and what is being given up in exchange. This article takes those questions in order: what doomscrolling is, how much time it takes, why it holds on, what it does to memory, mood and the brain, and what the same hours produce when they are spent differently.
The Short Version
| Question | Short answer |
|---|---|
| What is it? | Scrolling a feed passively: reading, watching and moving on without processing or using any of it |
| How much time does it take? | The average online adult spends about 967 hours a year on social and video feeds |
| Is it addictive? | It is habit forming by measurement, and 59% of people relapsed within a week of trying to stop |
| Does anything stay? | Very little. Memory is built by recalling and using information, not by seeing it once |
| How bad is it? | Heavy use is linked to anxiety, weaker attention and impulse control, and differences in brain structure |
| What could the time do instead? | Reach professional proficiency in a language, or read about 150 books |
What Doomscrolling Is
The word took hold around 2020 as a name for compulsively reading bad news. It has since widened. Today it describes any long session in a social or video feed where posts, clips and headlines are taken in one after another, with no pause to think about them and nothing done with them afterwards.
Two things define it. The content is chosen by an algorithm, not by the person watching. And the person is passive: nothing is looked up, written down, questioned or applied. Messaging a friend, following a tutorial, or watching something chosen on purpose happens in the same apps but is a different activity.
How Much Time It Takes
DataReportal's Digital 2026 report, drawing on survey data from GWI, found that online adults spend more than an hour a day on social networks such as Facebook and X. When video platforms such as YouTube and TikTok are added, the total rises to 18 hours and 36 minutes a week. Among women aged 16 to 24 it is 25 hours and 45 minutes a week.[1]
Over a year, the average comes to about 967 hours. That is 40 full days and nights, or roughly 121 eight-hour working days. Not all of it is passive scrolling, but the feed is designed so that most of it is, and the next section explains why that time is so hard to take back.
Why It Is So Hard to Stop
Doomscrolling is not a formal medical diagnosis, but it behaves like an addiction. The pattern is familiar to anyone who has tried to quit: the app is deleted and the urge to reinstall it arrives within days, the site gets opened in a browser instead, a frozen account is quietly reactivated.
The feed is built to produce this. Each swipe may or may not bring something rewarding, and that uncertainty is what keeps the thumb moving, as explained in Why We Become Addicted to Our Phones. The research confirms the result:
- It is habit forming. In a randomized experiment with about 2,000 American adults published in the American Economic Review, temporary incentives to cut social media use kept working after they ended, which is the signature of a habit. The authors estimate that self-control problems account for 31% of all social media use: time people spend against their own wishes.[2]
- Stopping produces withdrawal. When 152 people were asked to stay off social media for seven days, craving and boredom rose significantly, and 59% of them relapsed at least once during the week.[3]
- It is growing among the young. The World Health Organization reported that problematic social media use among adolescents, defined by addiction-like symptoms such as being unable to control use and feeling withdrawal without it, rose from 7% in 2018 to 11% in 2022 across 44 countries and regions.[4]
Why Nothing Stays
If those hours left knowledge behind, the habit would be easier to defend. They do not, because memory depends on what a person does with information, not on how much of it passes in front of them.
- Seeing is not retrieving. In a well-known experiment, students who practiced recalling a passage remembered substantially more of it a week later than students who simply read it again, even though the rereaders felt more confident.[5] A feed is rereading at its most extreme: thousands of items, each seen once, none recalled.
- Access is mistaken for knowledge. Across nine experiments, Yale researchers found that people who had just looked things up online rated their own understanding higher, mistaking access to information for knowledge in their own heads.[6] An earlier study in Science found that when people expect information to stay available, they remember less of it and more of where to find it.[7]
- Most of it is never opened. An analysis of more than 35 million public Facebook posts found that around 75% of the links people forwarded were shared without the sharer clicking on them first.[8] The headline was the whole encounter.
This is why an hour of scrolling leaves the feeling of having caught up with the world, and almost nothing that could be explained to someone else.
How Bad It Is: Mood, Attention and the Brain
Wasted time would be bad enough. The research suggests the habit also leaves a mark. Most of these studies show that heavy use and harm go together; only the experiments show one causing the other.
Mood
A 2026 systematic review and meta-analysis in Frontiers in Psychology covering 44 studies found doomscrolling associated with anxiety and depression (both r = 0.35), with psychological distress (r = 0.51), and with lower well-being and life satisfaction. The authors rated the certainty of the evidence as very low and stated that it does not establish causality.[9]
One experiment goes further. People asked to use Facebook passively, scrolling without posting or commenting, felt worse afterwards than those who used it actively. A follow-up that tracked people through their day found the same pattern and pointed to envy as the reason.[10]
Attention and self-control
A 2025 meta-analysis in Psychological Bulletin, pooling 71 studies and 98,299 participants, found that heavier use of short-form video went with poorer cognition overall (r = -.34), most strongly for attention (r = -.38) and inhibitory control (r = -.41).[11] Those are the two abilities a person needs in order to put the phone down.
In a controlled experiment with 60 participants, a break spent on TikTok significantly reduced people's ability to carry out a task they had planned beforehand. Breaks spent on Twitter, on YouTube, or resting did not.[12]
The brain
Brain imaging shows the same picture from the inside. A 2025 study in NeuroImage scanned people from the general population and found that stronger symptoms of short-video addiction went with larger volume in the orbitofrontal cortex, a region central to reward and impulse, and in the cerebellum, along with heightened resting activity in areas involved in self-control.[13]
In children the stakes are higher. A 2025 study in JAMA followed American children in a large national cohort and found that those whose social media use rose over time scored lower on reading and memory tests two years later than those who used little or none.[14] A fuller account is in Social Media's Influence on Brain Function and Behavior.
Three Deeper Costs
Mood and attention can be measured. Three further costs follow from how the feed works. They are harder to put a number on, and they may matter more.
- A mind filled with junk connections. The brain links things it meets together. A feed places a tragedy next to a joke next to an advertisement next to a stranger's opinion, hundreds of times an hour, with no time to sort any of it. What gets stored is a pile of shallow, unrelated associations in place of organized knowledge. No study has shown that scrolling lowers intelligence itself, but the abilities it is tied to, attention, impulse control, reading and memory, are the ones intelligence is built from.
- From problem solver to observer. Skills grow with use and fade without it. Analysis is a skill: noticing a problem, weighing options, deciding, and checking the result. A feed asks for none of that. It trains hours of watching other people do things, and what a person practices daily is what they become good at. The risk is carrying the same posture into real life, watching events as content when they call for a response.
- Fewer experiences of your own. The hours come from somewhere. They are taken from doing things, going places, and being with people, which is where a person's own stories come from. The screen even thins the experiences that do happen: in a series of experiments, people who used media to record or share an experience remembered it less well in a surprise test than those who simply lived it.[15] Years of watching other lives leave little to tell one's own children about.
What the Same Hours Could Build
The clearest way to see the cost is to ask what else 967 hours a year can do. The comparison here is with research in the everyday sense: starting with a question, finding the best sources on it, reading them properly, and coming out with an answer you can use.
| What 967 hours a year is equal to | The arithmetic |
|---|---|
| Professional proficiency in a new language | The US Foreign Service Institute budgets 24 weeks of 40 hours (23 in class, 17 of self-study), or 960 hours, to bring a diplomat to general professional proficiency in languages such as Italian, Portuguese, or Dutch[16] |
| About 150 books | At the average adult reading speed of 238 words a minute for non-fiction,[17] 967 hours covers about 13.8 million words, or roughly 150 books of 90,000 words each |
| Half a working year on one subject | 967 hours is about 121 eight-hour days, close to six months of full-time work |
Research produces this much because it reverses each thing that makes the feed empty:
| Scrolling a feed | Researching a question | |
|---|---|---|
| Who chooses the topic | The algorithm | You, starting from a question |
| How often a topic returns | Never; the subject changes every few seconds | Repeatedly, from several sources |
| What you have to produce | Nothing | A note, a comparison, a decision |
| What happens afterwards | The next post | The answer gets used |
Nobody will convert every minute of feed time into study, and nobody should try. Even a quarter of the average, about four and a half hours a week, comes to more than 240 hours a year: enough to read around 38 books or to work through a subject in real depth.
How to Get the Hours Back
Because the habit behaves like an addiction, willpower alone rarely works. These steps change the situation instead of relying on resolve.
- Move the apps. Take feed apps off the home screen, log out after each use, and turn off their notifications. Each added step breaks the automatic reach. The reasoning is set out in Digital Minimalism.
- Keep a question list. Write down things you actually want to know. When you reach for the phone, open the list and pick one.
- Search instead of browsing. Go to a search engine or an AI assistant with a question, not to a feed with none. How to choose between them is covered in How People Search for Information Now.
- Write three lines afterwards. What you learned, where it came from, and what you will do with it. This single habit turns reading into retrieval.
- Save, then return. If a post is worth knowing, save it and come back with time to read the source. If you never come back, it was not worth knowing.
- Expect the urge. Craving in the first week is normal and most people slip at least once. A slip is not a reason to give up.

The Bottom Line
Doomscrolling is worse than wasted time. It is a habit engineered to resist stopping, it leaves almost nothing in memory, and the evidence ties it to lower mood, weaker attention and differences in the brain. What it takes is larger still: the skills that are not practiced, the experiences that are not lived, and close to a thousand hours a year that could have built something. The hours are already being spent. The only choice is where they go.
