TikTok ruined my attention span? What's going on, and how to get your focus back

7 min read

A two-hour movie feels impossible. A friend sends a six-second video and you speed through it. You open a book and you're on your phone a page later. If that sounds familiar, you're far from the only one. Your attention probably isn't broken. It's been trained by a feed that hands you something new every few seconds, and it can be trained back. Here's what short videos do to focus, what the research actually shows, and five steps that help.

Is your attention span really broken?

Here's a test. Can you still lose yourself in a game, a long conversation, or a show you love? Most people can. A lot of people describe it the same way: they can still read for hours or sit through a three-hour movie, but once they start scrolling Reels, they can't stop. That isn't a broken attention span. It's a feed that's very good at keeping it.

What has changed is how often we switch. Psychologist Gloria Mark at UC Irvine has watched how people work on computers since the early 2000s. In her studies, the average time people stayed on one screen before switching was about two and a half minutes in 2004. In recent years it's been around 47 seconds. That measures switching, not a limit built into your brain, but it shows how used we've become to moving on.

What do studies say about short videos and attention?

A 2025 review in Psychological Bulletin pooled 71 studies with about 98,000 people. Heavier short-form video use went along with poorer attention and weaker inhibitory control (the ability to stop yourself from acting on an impulse). The authors are clear that these studies are mostly snapshots: they show the two go together, not that the videos caused the change. People who already struggle to focus might also be drawn to short videos. So treat it as a warning sign, not a verdict on your brain.

What short videos do to focus

Every swipe is a switch

Each new video is a new topic, a new voice, a new mood. Your brain has to drop one thing and pick up the next, dozens of times in a few minutes. In a 2023 experiment at LMU Munich, 60 people had to remember to do something later while they took a break. Those who spent the break on TikTok-style short videos were worse at remembering than those who used Twitter, watched YouTube, or rested. The researchers pointed to the rapid switching between short clips.

Counter-move: When you need to remember something or think something through, don't take your break in a short-video feed. A walk, a drink, or looking out of a window doesn't reset your mind the same way.

Skipping makes everything more boring

It feels efficient to skip the dull part. But in seven experiments, psychologists Katy Tam and Michael Inzlicht found that people who could skip between videos ended up more bored, and enjoyed what they watched less, than people who watched one video through. When the next thing is always one swipe away, part of your attention stays on leaving. Then anything long, like a movie, a lecture or a book, feels slow by comparison.

Counter-move: Practise finishing things: one whole song, one full episode, one article to the end. Notice the itch to move on, and let it pass without acting on it.

The feed is always one tap away

Focus isn't only about effort. It's also about what's competing for it. When the feed sits in your pocket, every slow moment in a book or a task is a moment where something easier is waiting. Many people find they don't have to fight that urge once the feed simply isn't there.

Counter-move: Take the feed out of reach while you focus, instead of trying to ignore it. The steps below show how.

The good news: focus comes back

In a 2025 experiment, 467 adults used an app that blocked mobile internet on their phones for two weeks. Calls and texts still worked. Afterwards they did better on a computer test of sustained attention, and reported better mental health and well-being. The researchers compared the size of the attention gain to about ten years of age-related decline. Not everyone stuck with the block, and two weeks of no mobile internet is a lot. But it shows that the focus people feel they've lost isn't gone. It returns when the constant pull does.

How to get your attention span back: 5 steps

Lock the short-video apps first. Don't rely on "I'll just watch less." On iPhone, make a Custom category in Settings › Screen Time › Time Allowances with TikTok, Instagram and YouTube in it, set it to 0 min, and let someone else type the Screen Time passcode. Shorts live inside YouTube, so locking Shorts means locking YouTube. Full walkthrough →
Put the phone in another room when you want to focus. Out of reach beats out of mind. If you need it for an alarm or a timer, use a cheap kitchen timer instead.
Start with something that has an ending. A chapter, an episode, an album. Start with 10 to 15 minutes and add a little each week. Choose something you actually enjoy. This isn't the time for the dullest book on your shelf.
One screen at a time. No scrolling while a show is on. If the show isn't worth watching on its own, that's useful to know too.
Expect restlessness, and plan for it. The first days usually feel itchy. Decide now what you'll do when the urge to switch hits: stand up, get a glass of water, give it five minutes. What to do when the urge hits →

A note on "brain rot": Oxford named it Word of the Year for 2024, describing the supposed decline of someone's mental state from too much trivial online content. It's a good word for the feeling, but it isn't a diagnosis, and the feeling usually eases when the feed goes. If trouble focusing stays with you even with your phone far away, it's worth talking to a doctor.

Lock the feed, keep your phone

Setting up Screen Time by hand works, but it's fiddly: a custom category, a zero allowance, someone to hold the passcode. Pactroll does it in one place. Pick TikTok, Reels, Shorts or whatever pulls you in, and they stay locked until you decide otherwise, even when Pactroll is closed. When the urge to check hits, "I feel the urge" walks you through naming it and five minutes of something else. If you still want in after two rounds, the apps open for 15 minutes, then lock again on their own.

FAQ

Did TikTok ruin my attention span?

Probably not for good. Studies link heavy short-video use with weaker attention, but they can't show that the videos caused it, and many people find they can still focus on things they care about. What the feed does is train you to expect the next thing every few seconds. When the feed is out of reach, attention tends to come back.

How long does it take to get your attention span back?

There's no fixed number. In a 2025 study, adults who blocked mobile internet on their phones for two weeks did measurably better on a sustained-attention test afterwards. Expect the first days to feel restless, and the change to show up over weeks, not overnight.

Can I fix my attention span without deleting TikTok or Instagram?

Yes. You don't need to delete anything. Lock the short-video apps so they aren't one tap away (on iPhone, a Screen Time allowance of 0 minutes with a passcode someone else holds), and practise with things that have an ending: a chapter, an episode, an album.

Why can't I read a book anymore?

A page asks you to stay with one thing, while a feed hands you something new every few seconds. After a lot of the second, the first feels slow. Start small: 10 minutes with the phone in another room, a short book you actually want to read, and add time from there.
