How to rebuild your broken attention span

You’re taking breaks wrong.

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.

A weekly dispatch to make sure tech is working for you, instead of overwhelming you. From senior technology correspondent Adam Clark Estes.

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.

“It’s a myth to think that we should push ourselves to focus as long as possible and we’ll be more productive,” said Gloria Mark, the author of Attention Span: A Groundbreaking Way to Restore Balance, Happiness and Productivity and the Substack The Future of Attention.

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.

“We need to stop trying to recover from cognitive fatigue and overload by consuming more........
