How to rebuild your broken attention span

Ever find yourself hunched over your laptop, eyes glazed, slack jawed, and stunned by the quantity of information modern life is throwing at you? You might take a break to stare at your phone. Or you could try switching from one browser tab to the next while checking your email and inching closer to the day’s deadline.

Some people call this TikTok brain. Others call it brain rot. Either way, it feels like a distinctly 21st-century affliction, caused by scrolling through too many short-form videos and social media feeds that trains your brain to seek out little hits of dopamine and ruins your ability to focus on anything for more than a few seconds. People with the condition may not be able to read books or even watch feature-length films. They can’t do anything except watch little videos, leaving them prone, catatonic, faces blank and bright in the glow of their smartphone screens.

I don’t even use TikTok, but I feel this way all the time. Give me one hour to complete a task that requires even a medium amount of mental fortitude, and I’ll find 55 minutes’ worth of other things to do. It’s not that I’m avoiding the task. But once I get started, my mind wanders relentlessly, no matter how hard I try to keep it on track.

You can blame technology for doing this to you — and I do — but the real issue is with how we treat our brains. Generally speaking, the human brain works like an analog computer, processing one thing at a time, and when you switch tasks (which is what we’re actually doing when we say we are multitasking), it comes at a cost: It drains your cognitive resources, which makes it even harder to pay attention in the future. The more you do this, the more ingrained the behavior becomes.

The human attention span is not one thing. There are different types of attention, including sustained attention (your ability to stay engaged with a task over a period of time) and selective attention (your capacity to take in certain information while tuning out irrelevant details). Alternating attention (the mental flexibility required to switch tasks rapidly) and dividing attention (process multiple things at once) are especially demanding on your cognitive resources. And all of this is managed by the brain’s command center, your prefrontal cortex, which handles executive function. When you’re experiencing cognitive fatigue, there’s a physical reason why: There’s actually less blood flowing to this portion of the brain.

The good news is that the damage is not permanent. The human brain’s capacity to focus is just as intact as it was in the 19th century when everyone spent their evenings reading novels and knitting fisherman sweaters. Lots of things have changed since then, of course. As smartphones have driven us to consume endless amounts of information, psychologists have been working on strategies to put the pieces of our attention spans back together. I called a few of these attention experts hoping that they might tell me the secret to regaining my ability to focus. They all agreed that two things are necessary to solve the problem: Be intentional with your attention and let your brain rest.

“What we need most is the capacity to know where attention is, moment by moment, and greater agency over our attention so we can direct it intentionally,” Amishi Jha, a neuroscience professor at the University of Miami and author of Peak Mind, told me. “We need to stop trying to recover from cognitive fatigue and overload by consuming more information.”

Put another way, in order to reclaim your attention span, you first need to be mindful. That means spending less brain power dissociating on social media feeds and more on whatever you’re actually interested in. You also need to give your brain a chance to rest and recover. Staring at your phone will not help you recharge and reclaim your attention span. Staring at a tree, however, will.

One way to think about your own attention span is to consider what is voluntary and what is not. When something like a bright light or a loud noise grabs your attention, it engages your involuntary attention, which is effectively limitless. When you’re deciding to pay attention to something, however, you’re using your voluntary, or directed attention. This is a limited resource. As you’re making an effort to focus on something, like a book, your supply of directed attention runs down, but it can be replenished in specific ways.

This simpler way to understand how our attention works dates back to the 19th-century psychologists, like Williams James, but it’s making a comeback thanks to attention restoration theory (ART). This school of thought, first developed in the 1980s by University of Michigan psychology professors Stephen and Rachel Kaplan, suggests that spending time in nature restores your directed attention. The theory claims that the natural world does this by captivating our indirect, or involuntary, attention and allowing our cognitive resources to recover.

Imagine you’ve gone for a hike and happen upon a waterfall that’s so fascinating you can’t look away from it. Marc Berman, one of Stephen Kaplan’s former students and now a professor at the University of Chicago, refers to such a spectacle as a “soft fascination,” something that can grab your attention without consuming it, thus giving your mind space to wander. You might get the same effect from staring at a campfire or looking up at tree branches swaying in the breeze. Hard fascinations, by contrast, capture so much of your attention that you can’t look away and you can’t quickly recover. Times Square is a canonical example, but being on social media counts, too.

In one study Berman conducted, he and his team (which included Kaplan) gave research subjects difficult attention and memory tasks, sent them on a walk in nature or an urban environment, and then repeated the tests. The participants who went on nature walks improved their performance in these tests by about 20 percent, Berman said, and the improvements held regardless of whether participants said they liked the walk or not.

Berman said they aren’t entirely sure why nature seems to have this effect on us, but he theorizes that it relates to fractals, or repeating, self-similar patterns whose individual parts resemble their larger whole — tree branches or fern leaves, for instance. Fractals are common in nature, and Berman thinks their orderly arrangement helps our brains to process the information. “It’s easy to get the gist and you don’t need to encode all the details,” he said. “Whereas in the built environment, it’s not very fractal and you might have to encode everything, which might be more taxing.”

Of course, it’s not always possible to zip over a forest in the middle of the work day. If you can’t take a walk in the park, Berman said that even looking at a picture of nature scenes can help. (Try not to do that on Instagram, though, because you might end up just doomscrolling.)

Reclaiming your attention is one thing, but holding onto it in the first place is its own distinct challenge. When you find yourself feeling distractable, it might be that you need a break. If that’s the case, you can’t will your way into concentrating.

“One of the great misconceptions about attention is that it’s simply a matter of us paying attention,” said Nilli Lavie, a professor of psychology and brain sciences at University College London. “It’s not enough to just want to pay attention.”

Instead, you have to put yourself in an environment that makes paying attention not only possible but achievable. That means making a concerted effort to avoid multitasking, which will drain your cognitive resources. Try the alternative: monotasking.

Monotasking likely requires clearing away clutter, whether that’s literal clutter on your desk, or digital clutter on your screen in the form of extra apps or browser tabs. Turning off all notifications is essential. You should also hide your phone — put it in a drawer or in another room. (A widely cited study published in 2017 found that even having a phone in sight can reduce your cognitive capacity and affect your ability to concentrate.) When you need to take a break, don’t go find your phone: Take a walk outside, or stare at a tree, or look out the window and listen to a song you like.

Monotasking also means being intentional about how you do that one thing, avoiding distractions along the way. At work, this might mean carving up projects into digestible chunks. You might even try the Pomodoro technique: Set a timer for 25 minutes, focus hard on the task until it goes off, take a five-minute break, and repeat. At home, it could mean making to-do lists and prioritizing tasks so that the toughest ones get done first, while you still have some gas in the tank.

If you aren’t ready to turn off all notifications at this point, at the very least turn off all the ones that aren’t coming from humans. You do not need to be alerted of an Amazon flash sale while you’re trying to plan your family’s meals for the week.

There’s no such thing as being 100 percent locked in to any given task. When there are no external distractions, your brain actually turns inward and finds something else to pay attention to, which can lead to daydreaming and mind wandering. Daydreaming — creating a structured narrative of imaginary scenarios — is not necessarily a bad thing, by the way. It can be productive in helping you plan and think creatively. But if you’re just mentally wandering from random topic to topic, you’re getting into the danger zone.

Some people find that adding constraints can improve their attention. One approach you’ll see in self-help books is the use of a so-called commitment device that restricts future behavior in service of a larger goal. If you’ve read (or seen) The Odyssey, you might remember the scene in which Odysseus orders his crew to tie him to the ship’s mast and ignore his orders so that he won’t steer the boat into the rocks when he hears the Sirens’ call. Odysseus was using a commitment device to avoid killing his whole crew. You might use a commitment device, like a dedicated writing space or the Pomodoro technique, to avoid distractions, both external and internal.

So how do you focus just the right amount? Removing those external distractions is a great start. Much like paying attention, ignoring these distractions consumes your cognitive resources, impacting your performance, and causing you to make mistakes. It also takes more effort to stay on task as time goes on. From there, do your best to avoid overtaxing your brain to the point that the internal distractions take over and your mind is wandering. That’s how you know it’s time to take a break.

“For several minutes, give yourself no new input,” Jha said. “Do not reach for the phone while waiting in line. Take a short walk without listening to anything. Look out a window. Let the mind wander without trying to solve a problem.”

Take a walk in the park. Sit quietly and look at a bird. Paying attention has never sounded so relaxing.
