You sit down to read, work or watch something longer than a minute, and your mind slides off it. You reach for the phone before you have decided to. It feels like something in you has broken.
It probably has not. The research is more hopeful than the feeling, and it points to a fairly plain way back.
Is short-form video really hurting your attention span?
The evidence says there is a link, and it is worth being exact about what kind.
A 2025 meta-analysis in Psychological Bulletin pooled 71 studies covering about 98,299 people. Heavier short-form video use was linked to poorer attention and, most strongly, poorer inhibitory control, which is the ability to stop yourself doing the easy thing. It was also linked to more stress and anxiety.
This is correlational. It shows the two travel together, not which one causes the other. Someone who already struggles to focus may drift toward short video, and the reverse may also be true.

Why does it feel so hard to focus on anything slower?
Part of it may be what the viewing itself does in the moment.
In an EEG study of 48 people, a higher short-video addiction tendency correlated with lower prefrontal theta activity during an attention task, and with lower self-control. Another study found that people learning from short videos had lower immediate memory accuracy and forgot faster than those learning from longer ones.
Both are single studies, so hold them loosely. But they fit what many people describe: slower material can feel thin by comparison.

How long does it take for your attention span to recover?
Nobody can give you an honest exact number, and anyone who does is guessing.
The best evidence is a randomised controlled trial. Castelo and colleagues, publishing in PNAS Nexus in 2025, had 467 participants block mobile internet on their smartphones for two weeks. Sustained attention improved by an amount the authors compared to about 10 years of age-related decline. Mental health and subjective wellbeing improved too. Calls and texts still worked, and increased nightly sleep was one of the mechanisms.
That tells you change can show up within a fortnight. It does not tell you that your attention will be fully back by day 14, or that it works the same way for stopping one app. The block was also imposed by the study, which is easier than choosing it every evening.

Does the phone just being nearby matter?
It might. In one study, people did best on working-memory and fluid-intelligence tests with their phone in another room and worst with it on the desk, even when it was silenced and unused. Later replications found smaller or mixed effects, so treat this as a cheap thing to try rather than a proven rule.

Is it the habit, or the screen time?
Often the habit. Most phone use is not prompted from outside. An observational study of real-life smartphone use found that about 89% of interactions were started by the user, not by a notification.
So the reach is frequently the problem, and it may fire on cues: the sofa, the gap in a conversation, the bed. As a matter of observation, resolving to "just use it less" often fails on its own, which is why changing the place can help more than willpower.

What actually helps, step by step?
None of this is a clinical protocol. It is practical advice that follows the evidence above.
- Remove the feed first. Delete the app or block it in your phone's settings. The trial blocked mobile internet generally rather than one app, so treat this as a sensible way to apply it, not a tested one.
- Change the place, not just the intention. Charge the phone outside the bedroom. Leave it in another room when you need to concentrate.
- Start with short stretches of single-task focus. Ten or fifteen minutes of one thing, then a break that is not a screen. Lengthen it when it stops feeling like effort. This is a sensible way to rebuild, not a tested programme.
- Expect the first days to feel worse. Ordinary life can read as flat and restless when the fast input stops. That is not proof it is not working.
- Protect your sleep. A 2025 meta-analysis of 21 cohort studies and 548,338 people linked each extra hour of daily screen time to a bedtime about 13.2 minutes later, about 3-5 minutes less sleep, and higher odds of difficulty falling asleep. Increased nightly sleep was one mechanism in the trial above, so it is worth protecting.

- Let some boredom in. The urge to fill every gap is the habit you are retraining. Sitting through a few minutes of nothing is the exercise. This is advice, not a tested method.
If you want help with the hardest part, the first minutes after you put the phone down, Boredom's Daily Reset is a short guided pause for exactly that gap. You can do the rest without it.
The short version
Short-form video use is linked to poorer attention and weaker self-control, though the research shows association, not proof of cause. In one randomised trial, two weeks without mobile internet produced measurable gains in attention and wellbeing, though that trial did not test removing short-form video specifically.
There is no guaranteed timeline. Cut the feed, change where the phone lives, rebuild focus in small single-task stretches, and give it a couple of weeks before deciding whether it is working. Feeling scattered right now is common and does not mean you are broken.
