To improve your attention span, change what interrupts you before you try to change yourself. Turn off notifications (just receiving one hurts focus, even if you never look), keep the phone in another room, do one task at a time, protect your sleep, and train focus in short daily blocks that grow by a few minutes each week. The strongest single result so far: in a 2025 randomized trial, two weeks without mobile internet improved sustained attention by about as much as ten years of age-related decline. And no, your attention span is not shorter than a goldfish's. That statistic was never measured.
You open a book on Sunday afternoon with real intentions. Two pages in, you notice you have read the same paragraph three times. Your hand is already on the phone. You did not decide to pick it up. It simply arrived there, the way your tongue finds a chipped tooth.
If that sounds familiar, you do not have a broken brain. You have a trained one, and it was trained by an environment built to interrupt it. The good news is that the same machinery works in reverse. This guide covers what attention span really is, the myth you have probably heard, ten fixes with the research behind each, and a 30-day plan that pulls them together. It is part of our wider guide on how to learn, because attention is where every bit of learning starts.
Measure it first
Take our free attention span test before you change anything. It is a two-minute version of the Sustained Attention to Response Task (SART), a lab task researchers have used since 1997: digits flash, you tap every one except the 3. You get a score out of 100 plus three subscores for sustained focus, impulse control and steadiness. Take it again after the 30-day plan below and compare.
The goldfish myth: is your attention span really 8 seconds?
No. The claim that the average human attention span fell from 12 seconds in 2000 to 8 seconds in 2015, one second less than a goldfish, is one of the most repeated numbers on the internet and one of the least supported.
It traces back to a 2015 marketing report by Microsoft Canada's consumer insights team. The report did run its own survey and some EEG work, but the goldfish figures were not from that research. They were cited to a website called Statistic Brain. When BBC reporter Simon Maybin tried to find the original study in 2017, he could not. Neither Statistic Brain nor anyone else could point to research behind it (BBC, 2017). The goldfish half fares no better. A fish biologist the BBC spoke to said goldfish are perfectly capable learners.
The classroom version is shaky too. "Students switch off after 10 to 15 minutes" has been passed around education circles for decades. When physiologist Neil Bradbury went back to the primary studies, he found they did not support a fixed limit at all (Bradbury, 2016). Attention in lectures rises and falls throughout, depending on the speaker and the material, a pattern Wilson and Korn had flagged a decade earlier.
So what is true? Something more interesting. There is no single attention span, because attention is several skills:
- Sustained attention: staying on one thing, especially a dull thing, over time. This is what most people mean, and what the SART measures.
- Selective attention: keeping the relevant in and the irrelevant out, like following one voice in a loud bar.
- Attention switching: moving between tasks on purpose and getting back up to speed.
What has changed is not your biology but your habits. Gloria Mark at the University of California, Irvine has timed how long office workers stay on one screen before switching. In 2004 the average was about two and a half minutes. Around 2012 it was 75 seconds. In her more recent studies it was 47 seconds (Mark, 2023). That is not a limit on what your brain can do. It is a record of what you have practised doing, which is good news, because practice runs both ways.
What actually shortens your attention
Before the fixes, the forces. Each one points directly at a cure.
Notifications, even unread ones. In a clever 2015 experiment, people did the SART while researchers secretly sent calls or texts to their phones. Nobody answered. Just getting the buzz made people noticeably worse at the task, about as much as people who were actively texting or calling in earlier studies (Stothart, Mitchum & Yehnert, 2015). A notification is not a neutral piece of information. It is an interruption you pay for whether or not you respond.
Switching. Every time you change tasks, your brain has to unload one set of rules and load another, and that takes time. The cost is small per switch and large per day (Rubinstein, Meyer & Evans, 2001). Gloria Mark's team found that interrupted workers made up for lost time by working faster, and paid for it in more stress, frustration and effort (Mark, Gudith & Klocke, 2008).
Too little sleep. Of all the mental skills that suffer after a short night, simple sustained attention takes the hardest hit. A meta-analysis of the sleep-deprivation research found the largest effects precisely on vigilance tasks like the SART (Lim & Dinges, 2010).
A wandering mind. Even with no phone in sight, attention drifts. When Matthew Killingsworth and Daniel Gilbert pinged thousands of people at random moments, their minds were off-task 46.9% of the time, and they were less happy when it happened (Killingsworth & Gilbert, 2010). Mind-wandering is normal. What you can train is how quickly you notice it and come back.
Short-form video, probably. A 2025 meta-analysis of 71 studies and nearly 100,000 people found that heavier use of TikTok, Reels and Shorts went with poorer attention (r = -0.38) and weaker impulse control (Nguyen et al., 2025). Be careful with that one. It is a correlation. People who already struggle to focus may simply prefer 20-second videos. But it fits the pattern: what you practise, you get better at, and a feed is practice in switching every few seconds. If that rings true, read our guide on popcorn brain.
How to improve attention span: 10 fixes that work
You do not need all ten at once. Fixes 1 to 4 change your environment and do most of the work. Fixes 5 and 6 train the skill itself. Fixes 7 to 9 are the body. Fix 10 is for when you want a big reset.
1. Find your baseline
Take the attention span test, then do a second, rougher measurement in real life. Sit down with one task, start a timer, and stop it at the first strong urge to switch. For many people that number is a humbling three to six minutes. Write it down. Watching it climb over the next month is more motivating than any pep talk.
2. Turn off notifications, not just the sound
Given the Stothart result, silent mode is not enough. A buzz you feel or a banner you glimpse still pulls attention. Go through your phone and switch off every notification that is not from a person who might need you right now. Badges count too: a red dot is a small, constant reminder that something is waiting.
3. Put the phone in another room
Physical distance turns a reflex into a decision. If the phone is across the house, checking it means getting up, and that small cost is often enough to break the loop. A note on honesty here: a famous 2017 study claimed that the mere presence of your phone drains brainpower, but the effect turned out to be smaller than first reported. A 2023 meta-analysis of 22 studies found a small overall effect, clearest for memory and not significant for attention on its own (Böttger, Poschik & Zierer, 2023). The main reason to move the phone is not some invisible drain. It is that you cannot check what you cannot reach.
4. Do one thing at a time
Multitasking is really fast switching, and every switch has a reload cost. Close every tab that is not the task. Keep a scrap of paper next to you, and when a thought pops up ("email the plumber"), write it down and go back. You are not ignoring it, you are parking it, which calms the part of your brain that is afraid of forgetting.
5. Train the return, not the stare
This is the shift that changes everything. A long attention span is not a mind that never drifts. It is a mind that drifts and comes back quickly. Each return is a repetition, like a curl for a muscle, and a session with 30 returns is not a failure. It is 30 reps.
Mindfulness meditation is basically a structured version of this drill: you rest attention on your breath, notice when it wanders, and bring it back. In a randomized trial, two weeks of mindfulness classes (45 minutes, four times a week) cut mind-wandering and improved working memory and reading-comprehension scores, compared with a nutrition class (Mrazek et al., 2013). It was a small study of students, so treat it as promising rather than proven. But it costs nothing to try ten minutes a day.
The same goes for boredom. When a task gets dull, sit in it for one more minute instead of reaching for the phone. Boredom is not an emergency. It is the exact resistance you are training against.
6. Work in blocks, with real breaks
Attention on a monotonous task drops over time; psychologists call this the vigilance decrement. One elegant study found a simple way to stop it: people who briefly switched to a different small task twice during a roughly 50-minute vigilance task did not show the usual drop, while those who kept going did (Ariga & Lleras, 2011). Short, planned breaks are not a luxury. They reset the clock.
Start with 15-minute blocks and stretch toward 25 to 45 as it gets easier. The Pomodoro technique is a ready-made version of this, though there is nothing magic about 25 minutes. Pick a length you can finish, and stop for a few minutes before you begin to fade. A good break means standing up and looking at something far away, not opening a feed.
7. Protect your sleep
No focus technique survives a bad night. Since sustained attention is the first skill to fail when you are short on sleep, an extra hour in bed may do more for your focus tomorrow than everything else on this list. Charge the phone outside the bedroom, and if falling asleep is the real problem, read why melatonin is not fixing your sleep.
8. Move your body
A single bout of exercise gives thinking a small but reliable boost for a while afterwards. A large meta-analysis found small positive effects during, immediately after and some time after a workout (Chang et al., 2012). The practical move: a brisk 10 to 20 minute walk before a task that needs your full focus.
9. Go outside, ideally somewhere green
In a well-known experiment, people who walked for about 50 minutes through an arboretum did better on a demanding attention test afterwards than people who walked through busy city streets. Even looking at photos of nature helped a little (Berman, Jonides & Kaplan, 2008). The idea behind it, called attention restoration, is that nature holds your attention gently, without demanding it, which lets the effortful system recover. A walk in the park at lunch is a fine experiment to run on yourself.
10. Try a two-week mobile internet break
This is the heavy option, and the one with the strongest evidence. In a preregistered randomized trial with 467 adults, people used an app that blocked mobile internet on their phones for two weeks; calls and texts still worked, and so did the internet on a computer. Their screen time fell from about 5 hours a day to under 3. Their sustained attention improved by an amount the researchers compared to reversing ten years of age-related decline, and their mood and well-being improved too (Castelo et al., 2025).
You do not have to go that far to benefit. But if your test score is low and the other fixes have not moved it, two weeks is short enough to try and long enough to show you what your attention feels like without the feed. Our guide on how to stop doomscrolling walks through the softer steps first.
A 30-day plan to improve your attention span
Techniques fail when you try all of them on a Monday. Add one layer a week. One real focus block a day is the whole game.
| Week | Focus | Daily target | What you do |
|---|---|---|---|
| 1 | Baseline and triggers | One 10-minute block | Take the test, time your first urge to switch, switch off notifications, phone in another room during the block |
| 2 | Single-tasking | One or two 15 to 20 minute blocks | One tab, a parking list for stray thoughts, count each return as a rep, a short break between blocks |
| 3 | Deep work | One or two 25 to 45 minute blocks | A fixed start ritual (same desk, same drink, same timer), sit with boredom, ten minutes of mindfulness on most days |
| 4 | Long reading and learning | One 30 to 60 minute block | Read a real book or long article on paper or in one tab, then close it and recall what you read from memory |
Two details make the plan work. First, do not skip ahead even if you feel ready, because the early weeks build the trigger-free setup that the later weeks depend on. Second, the last step of week 4, recalling what you just read, turns attention into something you keep. Focus without a destination fades. Pointed at learning, it compounds; our guide on how to improve memory shows what to do with it next.
At the end of the month, retake the test. Many people find that the three or four minutes they started with have become twenty or thirty. Not because they found more willpower, but because they stopped spending it on resisting a buzzing phone.
How to learn with a short attention span
You do not need to fix your attention before you are allowed to learn. A short attention span mostly breaks one approach: the long, sit-and-absorb session. It does not break your ability to understand or remember. So build around it.
- Shrink the target. One concept, one page, one short lesson. Not "study chapter three."
- Set a finish line. Five to fifteen minutes. Knowing there is an end keeps the brain from bolting.
- Close it and recall. After the input, say or write what you remember. Testing yourself beats rereading by a wide margin, and it is also an attention rep, because it forces a second, active pass over the material.
- Stop while it still feels good. Ending on a small win makes the next session easy to start.
- Come back tomorrow. Short sessions spread over days beat one long one, at the same total time.
This is where short-form learning earns its place. It gives your novelty-loving brain something new, but inside one focused frame that ends, instead of an endless feed. The method behind steps 3 and 5 is covered in how to retain what you learn, and if long study sessions are your specific struggle, see why you can't focus when studying.
Is it a short attention span or ADHD?
Most people who feel scattered do not have ADHD. Stress, poor sleep and years of heavy phone use can all make focus feel thin. ADHD is different: it is a lifelong pattern that shows up in childhood and across many settings, at work, at home and in relationships, not just around screens. A test like ours measures your attention today; it cannot diagnose anything. If focus problems have been with you as long as you can remember and seriously get in the way of your life, talk to a doctor or psychologist. Our complete guide to learning with ADHD covers what helps.
How long does it take to improve your attention span?
Faster than most people expect. Removing notifications helps the same day. In the studies above, two weeks of mindfulness classes and two weeks without mobile internet both produced measurable changes. Making the new routine feel automatic takes longer: in the best-known habit study, it took a median of 66 days for a new behaviour to become automatic, with a wide range from 18 to 254 days (Lally et al., 2010). Expect a noticeable difference in two weeks and a new normal in about two months.
Where NerdSip fits
We build NerdSip, so weigh this accordingly. It is our answer to the "give your brain something better" part of the problem. You type any topic and get a fact-checked course of short lessons, about five minutes in total, and every lesson ends with a question you have to answer, so each session closes with recall instead of a scroll. It is designed to end, which a feed never does. It will not fix your attention for you. The fixes above do that. But it gives a rebuilt attention span somewhere worth going.

Frequently Asked Questions
How can I improve my attention span?
Start with your environment, because it does most of the work. Turn off notifications, keep the phone in another room while you focus, and do one task at a time. Then train the skill: work in daily focus blocks that grow from about 10 to 45 minutes over a month, take short real breaks, and practise bringing your mind back when it drifts. Sleep, exercise and time outdoors support all of it.
Is the average attention span really 8 seconds?
No. The claim that human attention spans fell to 8 seconds, shorter than a goldfish, comes from a 2015 Microsoft Canada marketing report that cited a website called Statistic Brain. When the BBC investigated in 2017, nobody could find a study behind the number. There is no single attention span; how long you can focus depends on the task, your sleep, your interest and your surroundings.
How long does it take to improve your attention span?
You can feel a difference within days of switching off notifications. Studies have found measurable improvements after two weeks, both from mindfulness training and from blocking mobile internet. For the new routine to feel automatic, expect around two months: the best-known habit study found a median of 66 days.
Does TikTok ruin your attention span?
It may not help. A 2025 meta-analysis of 71 studies found that heavier short-form video use went with poorer attention and impulse control. That is a correlation, so it cannot prove the videos cause the problem, since people who struggle to focus may simply prefer short clips. But a feed is constant practice in switching, and what you practise, you get better at.
Is a short attention span a sign of ADHD?
Not by itself. Stress, poor sleep and heavy phone use can all make focus feel thin. ADHD is a lifelong pattern that starts in childhood and shows up across many settings, not just around screens. An online test measures your attention today and cannot diagnose anything. If focus problems have been with you as long as you remember and seriously affect your life, talk to a doctor or psychologist.
What is the fastest way to improve focus?
Switch off notifications and move your phone out of the room. In one experiment, simply receiving calls or texts, without answering them, made people noticeably worse at an attention task. Removing the interruption is faster than any training, and it makes every other fix easier.
Can meditation improve attention span?
There is promising evidence. In a randomized trial, students who took a two-week mindfulness course, 45 minutes four times a week, had less mind-wandering and better working memory and reading-comprehension scores than students in a nutrition class. It was a small study, so treat it as a good bet rather than a guarantee. Ten minutes a day is enough to try it.
How do you learn with a short attention span?
Work with it rather than against it. Learn in short sessions of five to fifteen minutes with a clear finish line, close the material and recall it from memory at the end, stop while it still feels good, and come back the next day. Short sessions spread over several days beat one long session at the same total time.
