Essentially the most embarrassing factor occurred to me lately. It was twilight, and I used to be strolling my canine across the quiet Brooklyn neighborhood the place I’ve been residing for a few 12 months. Then I heard a sound that I couldn’t place at first. I finished in my tracks after which realized: Crickets have been chirping.
It was my first time listening to crickets in my new neighborhood as a result of it was one of many first occasions I’d walked by way of it with out AirPods jammed into my ears.
This occurred for a cause. Earlier this 12 months, I had the sudden realization that I used to be listening to too many podcasts and had been for years. What began out as a strategy to distract myself on lengthy subway rides turned a compulsion on lengthy walks throughout the pandemic. The subsequent factor I knew I’d be catching up on The Day by day whereas washing dishes or listening to 5 minutes of Radiolab as I took out the trash. Quickly, all of my quiet moments have been full of different individuals’s voices, and I felt like I couldn’t assume my very own ideas, even after I sat in silence. So I made a decision to stop podcasts for a month.
It’s outstanding what quitting one thing you get pleasure from can do to your worldview. However quitting podcasts additionally did one thing to my mind. As days stretched into weeks, I began to acknowledge some order returning to my ideas. Whereas podcasts stored my thoughts occupied always, the absence of them created house for me to give attention to one factor. My consideration span improved. I learn a few books. I smiled at my neighbors. I seen the crickets.
You would chalk all this as much as a placebo impact. I made a decision to be extra current and so I used to be. It’s like in the event you determine to cease consuming for Dry January and really feel more healthy the very subsequent day. However suspecting there was extra occurring upstairs, I reached out to psychologists, neuroscientists, and different researchers who examine cognition. They defined the science behind the mind’s default mode community, which controls your prepare of thought, and processes like notion, which helps us filter info to grasp the world round us, in addition to govt perform, which refers to your means to plan and to focus. Certainly, by turning off one relentless stream of stimulus, I used to be liberating up bandwidth in my mind. By not listening to different individuals’s tales, I may higher narrate my very own.
- The human mind is incapable of multitasking. Any time you assume you’re multitasking, you’re really switching duties quickly, and that comes at a cognitive price.
- Silence prompts the mind’s “default mode” — and that’s good. Quiet time makes house for self-reflection, planning, and daydreaming.
- Easy sensory experiences, like strolling outdoors with out headphones, restore cognitive assets much better than utilizing podcasts as background throughout breaks.
That conclusion sounds a bit apparent. What was much less apparent to me was that listening to podcasts whereas doing actually anything quantities to multitasking, which is unattainable. The human mind works like an analog pc, processing packets of data one by one, and our minds are very restricted in bandwidth, in accordance with Earl Miller, a professor of neuroscience at MIT.
“While you assume you’re multitasking, what you’re doing is activity switching,” Miller instructed me. “Your mind is quickly switching from one activity to a different on a regular basis, and also you don’t discover it. However it comes at a cognitive price.”
Thanks largely to smartphones, we’ve change into a society of meandering multitaskers. With screens continually in our peripheral imaginative and prescient — or in my case, earbuds all the time in my head — we’re switching forwards and backwards between the true and the digital world. In the meantime, a few of the hottest apps on these gadgets are designed to carry as a lot of our consideration for so long as potential. Podcasts invite you to hearken to the subsequent episode. Instagram impels you to maintain you scrolling. TikTok desires you to maintain watching.
As we more and more break up our consideration, we find yourself residing in the true world in a diminished capability. Our brains didn’t evolve to stay like this.
It might be helpful responsible smartphones for all my distractions, however the issue dates again to the ’90s when the Walkman dominated my youth. My household ran a restaurant in Tennessee, the place I used to be in command of washing dishes, a whole bunch of them, a number of nights every week. In pursuit of just a bit little bit of distraction, I spent these hours listening to mixtapes.
Then I went to varsity within the early 2000s and acquired my first iPod, the gadget for which podcasts are named. With 10,000 songs in my pocket, I’d stroll round campus hooked up to my earbuds. It was round this time that I discovered how music may really assist me focus — however provided that it was acquainted and normally lyric-free. Then got here life with an iPhone in New York, driving the subway with AirPods, and an itch to devour increasingly info in my free time.
It seems silence is basically good for you.
It wasn’t simply me, both. Between 2015 and 2025, the period of time People spent listening to podcasts elevated by 355 %. A few quarter of these listeners spend greater than 10 hours every week with their podcasts. Writing in New York Journal a couple of years in the past, journalist Sirena Bergman admitted to spending 35 hours every week listening to podcasts and puzzled the identical factor as me: What’s all this content material doing to my mind?
Listening to a piece week’s value of podcasts deprives your mind of lots of silence. And it seems silence is basically good for you.
There’s a mountain of scientific proof for this. In 2005, medical researcher Luciano Bernardi studied the physiological results of listening to completely different types of music. A lot to his shock, his topics have been most relaxed — their blood strain dropped, their coronary heart charge slowed — throughout the random two minutes of silence between the songs. Ten years later, neurobiologist Imke Kirste uncovered completely different teams of mice to sure sounds, all the things from Mozart to white noise to nothing in any respect, for 2 hours a day. Publicity to sound led to neurogenesis in all the mice, however these new cells became functioning neurons solely within the mice uncovered to silence. In different phrases, an absence of enter really made their brains develop.
Silence additionally permits your mind to create an inner narrative. Neuroscientist Marcus Raichle and a staff of Washington College researchers referred to as the baseline state of an unstimulated mind the “default mode” — and it’s really fairly lively even when at relaxation. Self-reflection occurs when your mind’s on this default mode community. It’s then that we assemble our autobiographical narrative, and that we daydream.
The areas of the mind that mild up in default mode additionally deactivate when your mind is doing different issues. While you’re listening to a podcast, for instance, it’s harder to your thoughts to wander. As Alexander Huth, a neuroscientist on the College of California Berkeley, defined to me, the exterior narrative takes over your inner narrative.
Podcasts particularly make it onerous to assume your individual ideas, since you’re specializing in another person’s story. Huth and his colleagues used an MRI machine to file individuals’s mind exercise whereas they listened to exhibits, like “The Moth Radio Hour.” This allowed them to make a map of individuals’s sensory, emotional, and reminiscence networks. Notably, Huth instructed me, “all of the default mode community areas monitor the content material of a narrative,” whether or not you’re listening to it in a podcast or round a campfire.
“When anyone is telling you a narrative you continue to have this operating prepare of thought occurring, however it’s not your internally generated one,” Huth mentioned. “You’re following anyone else’s operating prepare of thought.”
You’ll be able to change forwards and backwards between the podcast and your inner dialogue. However task-switching comes with a cognitive price. As I’d seen on my distracted subway rides, your thoughts can’t wander far when it’s being pulled in one other path.
Self-reflection, by the way in which, is tremendous essential. It improves all the things from your efficiency at work to your resilience to emphasize. Constructive considering when your mind is in default mode can even simply make you are feeling happier.
The crickets incident occurred within the second week of my experiment, and it didn’t take a neuroscience lesson for me to grasp why. As soon as I finished listening to podcasts, I began listening to the world. I heard birds singing, leaves rustling, and horns honking. What occurred within the house between — my thoughts wandered, I believed in regards to the day, I made plans — did have a extra refined scientific rationalization. With my mind left in default mode longer, my capability for self-reflection rebounded.
If I’m being sincere, I acquired bored, too. This was factor, for essentially the most half. I did miss being distracted from chores, although. My subway rides felt longer, and driving appeared much less enjoyable. Podcasts, I noticed, have been how I stuffed the idle however barely annoying minutes of my days. It didn’t really feel like lacking out on a lot if I have been listening to a historical past podcast whereas washing dishes or folding laundry. Fairly the opposite: I used to be studying about how the Medici household formed the banking system of the Center Ages or why the swing dancing craze of the Nineteen Nineties fizzled out so quick. However I might additionally discover myself barely distracted and needing to rewind the episode to relisten to one thing I missed.
The issue with doing two issues directly is that you just usually can’t.
Once more, the issue with doing two issues directly is that you just usually can’t. Not all duties are created equal, in fact. Studying medieval historical past is cognitively demanding, partially, as a result of your mind is taking in lots of new info. Washing dishes shouldn’t be, because you’ve executed it so many occasions the duty has change into automated.
“These automated behaviors don’t depend on the identical neural community that’s essential for consideration and cognitive management,” mentioned René Marois, a neuroscience professor at Vanderbilt. “However even throughout these automated behaviors, one thing can occur that may require consideration and cognitive management and that’s when issues can go awry.”
That is why, when my experiment ended, I didn’t return to my previous behavior of driving and listening to podcasts. Driving is automated sufficient that it’s not onerous to comply with a podcast, however paying shut consideration to episode is distracting sufficient that I would miss a flip, or worse.
Human evolution is responsible right here. Our brains advanced on a savannah, in an information-poor surroundings the place there wasn’t quite a bit to concentrate to, defined Miller, the MIT professor. That’s why we now have mechanisms to focus intently on one factor at a time. On the identical time, we developed a thirst for brand spanking new info, like rustling bushes, since that would point out a risk, like a tiger able to assault.
“Again when our brains first advanced, that was effective,” mentioned Miller. “However now, on this new world we’re residing in with all these screens and sources of data obtainable to us, it’s an ideal storm of cognitive confusion that our brains haven’t advanced to take care of.”
That mentioned, there may be proof that pairing sure duties can enhance consideration and focus. For a 2005 examine, researchers from Vrije Universiteit Amsterdam confirmed topics two targets on a display screen, a break up second aside. Most individuals couldn’t spot the second as a result of a so-called attentional blink. The researchers theorized that folks have been overinvesting their consideration within the activity. After they performed some background music, nevertheless, they acquired higher at recognizing the second goal. The slight distraction supplied by music put them in a subtle state of consideration, barely bettering their focus.
This may assist clarify why I can write whereas listening to minimal techno however to not folks music. The digital beats take the sting off, whereas the woodsy lyrics interact the components of my mind that course of language. Or, if I’m again in my ancestral savannah, the grass rustling within the breeze is calming, whereas a stunning snarl is trigger for alarm.
It’s actually onerous to cease multitasking within the twenty first century. Even throughout my podcast experiment, which ended with me being somewhat obsessive about quiet time, I’d discover myself reaching for my telephone throughout conversations or chatting in Slack whereas ending up a draft. However figuring out what I now learn about how our brains work, I’ve a brand new reverence for break time.
That is previous recommendation: When you end up caught on one thing, put it down and are available again later with contemporary eyes. However to construct on that, once you take a break, don’t change out of your laptop computer to TikTok. Go outdoors and have a look at a tree.
Listening to podcasts, enjoyable as it might appear, depletes your cognitive assets.
“Among the finest issues that folks can do is to take a break, go outdoors in nature,” mentioned Gloria Mark, professor of informatics on the College of California Irvine and creator of Consideration Span. “Simply being away from media and utilizing our full vary of senses can assist restore our cognitive assets.”
Your mind runs on cognitive assets, and specializing in duties drains these assets because the day goes on. Doing a tough math drawback prices you cognitive assets. So does having an intense dialogue. Listening to podcasts, enjoyable as it might appear, depletes your cognitive assets, too. When you’re attempting to do two issues directly, you’re activity switching, forcing your mind to retrieve particular info for every activity, and carrying your self out. Because of this, it takes longer to do every activity, and also you’ll most likely make extra errors. You’ll even be extra confused alongside the way in which.
Listening to podcasts whereas doing at the very least one different factor was once my break time. I wouldn’t essentially care what the podcast was about or take up the knowledge therein. I’d simply let the media wash over me like a river over stones.
This was, looking back, a awful strategy to unwind. As of late, I put on my headphones much less. I really have a look at my telephone much less, if solely as a result of I’m not continually pulling up a contemporary podcast. Once I stroll my canine, I stroll to the park and hearken to the swaying grass and hearken to the timber. The one factor sweeter than the sound of crickets there may be the occasional sigh of silence.
Correction, December 3, 5 pm ET: A earlier model of this submit misstated the college the place Gloria Mark works.
