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 yr. Then I heard a sound that I couldn’t place at first. I finished in my tracks after which realized: Crickets had 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 it with out AirPods jammed into my ears.
This occurred for a cause. Earlier this yr, 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 approach to distract myself on lengthy subway rides grew to become a compulsion on lengthy walks in the course of the pandemic. The following 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 had been crammed with different folks’s voices, and I felt like I couldn’t suppose my very own ideas, even after I sat in silence. So I made a decision to give up 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 saved my thoughts occupied always, the absence of them created area 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 possibly can 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 if you happen to resolve to cease ingesting 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 know the world round us, in addition to govt perform, which refers to your capacity to plan and to focus. Certainly, by turning off one relentless stream of stimulus, I used to be releasing up bandwidth in my mind. By not listening to different folks’s tales, I may higher narrate my very own.
That conclusion sounds a bit apparent. What was much less apparent to me was that listening to podcasts whereas doing actually the rest quantities to multitasking, which is unimaginable. The human mind works like an analog laptop, processing packets of knowledge one by one, and our minds are very restricted in bandwidth, based on Earl Miller, a professor of neuroscience at MIT.
“Whenever you suppose you’re multitasking, what you’re doing is activity switching,” Miller informed me. “Your mind is quickly switching from one activity to a different on a regular basis, and also you don’t discover it. Nevertheless it comes at a cognitive value.”
Thanks largely to smartphones, we’ve change into a society of meandering multitaskers. With screens always in our peripheral imaginative and prescient — or in my case, earbuds at all times in my head — we’re switching backwards and forwards between the true and the digital world. In the meantime, a number of the hottest apps on these units are designed to carry as a lot of our consideration for so long as attainable. 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 cut up our consideration, we find yourself residing in the true world in a diminished capability. Our brains didn’t evolve to reside like this.
It might be helpful accountable 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 accountable for washing dishes, tons of of them, a number of nights per week. In pursuit of just a bit little bit of distraction, I spent these hours listening to mixtapes.
Then I went to school within the early 2000s and bought 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 realized how music may truly assist me focus — however provided that it was acquainted and often lyric-free. Then got here life with an iPhone in New York, driving the subway with AirPods, and an itch to devour increasingly more info in my free time.
It seems silence is de facto good for you.
It wasn’t simply me, both. Between 2015 and 2025, the period of time Individuals spent listening to podcasts elevated by 355 p.c. A couple of quarter of these listeners spend greater than 10 hours per week with their podcasts. Writing in New York Journal a number of years in the past, journalist Sirena Bergman admitted to spending 35 hours per 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 numerous silence. And it seems silence is de facto 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 kinds of music. A lot to his shock, his topics had been most relaxed — their blood strain dropped, their coronary heart price slowed — in the course of the random two minutes of silence between the songs. Ten years later, neurobiologist Imke Kirste uncovered completely different teams of mice to sure sounds, every part from Mozart to white noise to nothing in any respect, for 2 hours a day. Publicity to sound led to neurogenesis in the entire mice, however these new cells become functioning neurons solely within the mice uncovered to silence. In different phrases, an absence of enter truly made their brains develop.
Silence additionally permits your mind to create an inside narrative. Neuroscientist Marcus Raichle and a workforce of Washington College researchers referred to as the baseline state of an unstimulated mind the “default mode” — and it’s truly fairly energetic 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 gentle up in default mode additionally deactivate when your mind is doing different issues. Whenever you’re listening to a podcast, for instance, it’s harder in your thoughts to wander. As Alexander Huth, a neuroscientist on the College of California Berkeley, defined to me, the exterior narrative takes over your inside narrative.
Podcasts particularly make it onerous to suppose your personal ideas, since you’re specializing in another person’s story. Huth and his colleagues used an MRI machine to file folks’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 informed me, “all of the default mode community areas observe the content material of a narrative,” whether or not you’re listening to it in a podcast or round a campfire.
“When someone is telling you a narrative you continue to have this working prepare of thought taking place, nevertheless it’s not your internally generated one,” Huth mentioned. “You’re following someone else’s working prepare of thought.”
You’ll be able to change backwards and forwards between the podcast and your inside dialogue. However task-switching comes with a cognitive value. 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 best way, is tremendous vital. It improves every part out of your efficiency at work to your resilience to emphasize. Optimistic 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 know 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 area between — my thoughts wandered, I assumed in regards to the day, I made plans — did have a extra subtle scientific rationalization. With my mind left in default mode longer, my capability for self-reflection rebounded.
If I’m being sincere, I bought bored, too. This was a very good 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, had 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 had 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 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 without delay is that you simply sometimes can’t.
Once more, the issue with doing two issues without delay is that you simply sometimes can’t. Not all duties are created equal, after all. Studying medieval historical past is cognitively demanding, partly, as a result of your mind is taking in numerous new info. Washing dishes isn’t, because you’ve finished it so many occasions the duty has change into computerized.
“These computerized behaviors don’t depend on the identical neural community that’s vital for consideration and cognitive management,” mentioned René Marois, a neuroscience professor at Vanderbilt. “However even throughout these computerized behaviors, one thing can occur that may require consideration and cognitive management and that’s when issues can go awry.”
Because of this, when my experiment ended, I didn’t return to my outdated behavior of driving and listening to podcasts. Driving is computerized sufficient that it’s not onerous to observe a podcast, however paying shut consideration to a very good episode is distracting sufficient that I would miss a flip, or worse.
Human evolution is accountable right here. Our brains advanced on a savannah, in an information-poor surroundings the place there wasn’t rather a lot 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 new info, like rustling bushes, since that might point out a menace, like a tiger able to assault.
“Again when our brains first advanced, that was wonderful,” mentioned Miller. “However now, on this new world we’re residing in with all these screens and sources of knowledge accessible to us, it’s an ideal storm of cognitive confusion that our brains haven’t advanced to cope with.”
That mentioned, there’s 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, a cut up second aside. Most individuals couldn’t spot the second on account of a so-called attentional blink. The researchers theorized that folks had been overinvesting their consideration within the activity. After they performed some background music, nevertheless, they bought higher at recognizing the second goal. The slight distraction provided 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 have interaction 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 shocking 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 moderately obsessive about quiet time, I’d discover myself reaching for my cellphone throughout conversations or chatting in Slack whereas ending up a draft. However understanding what I now find out about how our brains work, I’ve a brand new reverence for break time.
That is outdated recommendation: When you end up caught on one thing, put it down and are available again later with recent eyes. However to construct on that, whenever you take a break, don’t change out of your laptop computer to TikTok. Go exterior and take a look at a tree.
Listening to podcasts, stress-free as it could appear, depletes your cognitive sources.
“Probably the greatest issues that folks can do is to take a break, go exterior in nature,” mentioned Gloria Mark, professor of informatics on the College of California San Diego and writer of Consideration Span. “Simply being away from media and utilizing our full vary of senses might help restore our cognitive sources.”
Your mind runs on cognitive sources, and specializing in duties drains these sources because the day goes on. Doing a tough math drawback prices you cognitive sources. So does having an intense dialogue. Listening to podcasts, stress-free as it could appear, depletes your cognitive sources, too. In the event you’re making an attempt to do two issues without delay, you’re activity switching, forcing your mind to retrieve particular info for every activity, and sporting your self out. In consequence, it takes longer to do every activity, and also you’ll in all probability make extra errors. You’ll even be extra confused alongside the best way.
Listening to podcasts whereas doing a minimum of one different factor was my break time. I wouldn’t essentially care what the podcast was about or soak up the knowledge therein. I’d simply let the media wash over me like a river over stones.
This was, looking back, a awful approach to unwind. As of late, I put on my headphones much less. I truly take a look at my cellphone much less, if solely as a result of I’m not always pulling up a recent 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’s the occasional sigh of silence.
