How do you improve your attention span?

You improve your attention span by deliberately practising sustained focus, a little every day, while tolerating the urge to switch. That works because attention is not a fixed trait you are born with a set amount of. It is a trainable capacity, like strength or stamina. The shortened, restless focus so many people now report is not permanent damage. It is the result of how the modern day is structured, and structure can be changed.

Why has my attention span got so short?

47 seconds is roughly how long people now stay on a single screen before switching, down from about two and a half minutes in 2004. The informatics researcher Gloria Mark spent two decades measuring this, and by 2021 the average had fallen to that 47 seconds.^[1] We did not get worse at attention as people. We built an environment that rewards switching, then practised switching thousands of times a day until it became automatic.

That is the bad news and the good news in one sentence. If a short attention span is a learned habit, it can be unlearned, because the brain that learned it is plastic.

What causes poor concentration?

Most often, everyday things: poor sleep, stress, constant interruptions and trying to do several things at once. The NHS lists finding it difficult to concentrate during the day as a symptom of insomnia,^[4] and difficulty concentrating as a sign of generalised anxiety.^[5] It can also go with menopause, which the NHS says can bring problems with memory or concentration,^[6] and with ADHD in adults, where being easily distracted is one of the signs.^[7] Your surroundings count too: on screens, attention now switches roughly every 47 seconds on average.^[1] The free fixes come first: more sleep and fewer interruptions.

The caveat: this is general information, not medical advice, and only a doctor can tell you what is behind it. If poor concentration lasts for weeks, comes on suddenly, or is affecting your work, studies or relationships, see your GP.

Can you actually improve your attention span?

Yes. The clearest evidence that focus responds to practice comes from training studies, and the reading brain tells the same story over a longer horizon. The cognitive neuroscientist Maryanne Wolf describes the deep-reading circuit, the network of brain regions that lets you follow a long, complex argument, as something that is built through practice and maintained through use.^[3] It is not given. Skim all day and the circuit weakens. Read deeply and regularly and it holds. The capacity follows the behaviour.

How long does it take to improve your attention span?

2 weeks was enough for measurable gains in one controlled experiment, though several weeks is the realistic frame. Participants who completed a two-week course of short daily attention and mindfulness sessions showed measurable improvements in working-memory capacity and reading-comprehension scores, and reported significantly less mind-wandering, compared with a control group.^[2] Small, regular sessions beat occasional long ones.

What are the best exercises for attention span?

5 habits do most of the work. The principle behind every one is the same: deliberately practise staying with one thing while tolerating the urge to switch. That urge is the rep. Sitting with it is the exercise.

Read on paper, daily. Sustained reading is the closest thing to a complete attention workout, because it demands continuous focus and a physical book cannot interrupt you. Start with a length you can actually hold, even ten minutes, and extend it. If you have lost the habit entirely, a paper book and a fixed time of day is the whole method.

Single-task in blocks. Pick one task, put the phone in another room, and work on only that thing for a set stretch. Twenty-five minutes is a common starting block. The skill you are building is not the work itself, it is staying when your mind reaches for something else.

Walk without audio. A walk with no podcast and no music is undirected attention practice. The mind wanders, returns, wanders again, and that gentle, unforced range is exactly what constant input has crowded out.

Reduce the background switching. Turn off non-essential notifications, keep one tab open instead of twenty, and stop checking the phone in the small gaps. Every avoided switch is a rep in the right direction.

Protect sleep and movement. Attention is a biological function before it is a psychological one. Tired, sedentary brains focus worse. None of the practice above lands well on no sleep. This is general information, not medical advice.

Is reading books good for your attention span?

Yes. Sustained reading on paper is one of the best exercises there is, because it asks for continuous focus with nothing to interrupt it.

The honest timeline is weeks, not days, and progress is uneven. But the direction is reliable: practise sustained attention and it returns. That is the whole premise of How to Be Bored Again, which treats focus not as a thing you have lost but as a muscle you can use again.
