Zazen for ADHD devs: what 20 minutes of sitting still does to my brain

My brain is loud.

I have ADHD. That's the short version. The long version is that my brain runs roughly seventeen tabs at once, half of them muted, all of them unfinished, and any attempt to close one spawns three more. If you know, you know. The thing I was going to do five minutes ago is being narrated over three other things I was also going to do, one of which I have already forgotten.

I've tried most of the usual tooling to manage this. Timers, lists, apps, hyperfocus-bait, productivity systems that last exactly until the novelty wears off. Some help a little. None of them give me quiet.

This is a post about the one practice that reliably does — and it's probably not what you expect. I sit on the floor in a temple for twenty minutes and stare at a wall. That's it. I'm going to tell you why a very old practice turned out to be the most effective thing I've found for an ADHD brain trying to do software work.

I'll cover: how I stumbled into this as a teenager, why I came back to it in college when the noise got unbearable, what twenty minutes of zazen actually feels like from the inside of an ADHD head, how it's changed my dev work specifically, and — most importantly — how you can just go, wherever you live.

The field trip I wasn't supposed to like

I grew up in Japan. At some point in high school my class got marched onto a bus and taken to a temple for a full day of Zen practice. This was not a spa day. It was a religious training school, and the schedule was: zazen (seated meditation), samu (cleaning work), shakyo (copying sutras by hand), and shojin ryori (vegetarian monastic food). No phones. No talking unless instructed.

Important context: I was at peak teenage everything is terrible mode. Boyfriend stuff, friend stuff, existential stuff. I had seen the temple's one-day trial flyer earlier and thought, only half joking, maybe I can get enlightened and skip the next three years of this feeling. So when the school trip landed on that same temple, I showed up ready.

We did the full day. We copied sutras with brushes. We got hit on the shoulder with a wooden stick (the kyosaku, it's a real thing, they ask if you want it first, it's not as scary as it sounds but you feel it). We scrubbed floors in silence. We ate rice and pickles with the kind of attention you normally reserve for a one-time thing.

And the weird part: something shifted. Not enlightenment, obviously. But the noise came down. It was a hot summer afternoon and normally my brain would have been complaining about the heat while simultaneously spinning on social drama and unfinished homework. That day, I just... noticed it was hot. The cicadas were piercingly loud in a way they usually aren't, because nothing else was competing for audio bandwidth. I walked out of that temple lighter than I walked in, even though I had just scrubbed a floor for an hour.

Fifteen-year-old me didn't have vocabulary for what had happened. I didn't have an ADHD diagnosis yet. I just remembered that for a few hours, my head had been quiet for the first time I could remember.

The noise got worse before I came back

Years passed. I went to university. My brain got louder, not quieter. ADHD in your late teens and twenties has a way of compounding — the stakes go up, the stimulation goes up, the number of tabs goes up, and the strategies that kind of worked when you were sixteen stop working when you have to manage your own schedule.

At some point in college, I hit a wall. Not a depression wall, more of a cognitive traffic jam. Too many open loops, no way to close any of them, and everything I tried — more coffee, more lists, more structure, louder music to drown out the inside noise — was a variation of "push harder against the chaos." Pushing harder is the default ADHD response and it mostly makes things worse.

I remembered the temple. I remembered walking out of it with a quiet head.

I looked up a drop-in zazen session near my university. I went alone. I was nervous, which was funny in retrospect because the thing I was nervous about was sitting still, which for an ADHD brain is a reasonable thing to be nervous about.

That was years ago. I now do it every few weeks. Not as discipline. Closer to brushing teeth for the mind.

What twenty minutes of zazen actually feels like in an ADHD brain

I want to describe this honestly because meditation gets talked about in two broken registers online. Either it's mystical (you will achieve inner peace), or it's clinical (studies show a 12% cortisol reduction). Neither is what it's actually like, especially not for ADHD brains.

Here's what it's like.

First few minutes: you sit cross-legged. Immediately, your knees protest. Your back, which has been slumped at a laptop all week, sends a formal complaint. Your brain, sensing stillness and interpreting it as threat, produces a surge of thoughts. You will at this point believe you are "bad at meditation." You are not. This is what happens to everyone. For ADHD brains, the surge is just louder.

Minutes five to ten: the thought storm. I think about: whether I sent that email, a joke I meant to tell someone three days ago, the weird noise my fridge makes, a conversation I had in middle school, the PR I haven't reviewed, whether I locked the door, the side project, the thing my coworker said in a meeting, the snack I want later. I cannot stop any of them. The practice isn't stopping thoughts — it's noticing each one and not following it down the staircase.

My personal hack for this: I imagine a tiny trash icon floating in the corner of my mind, and I drag each thought into it. Fridge noise — trash. Middle school memory — trash. Did I lock the door — trash (I did). Is this the authentic traditional technique? No. Does it work for a software-shaped ADHD brain? Yes, remarkably well.

Minutes ten to fifteen: something gives. Not always, but often. Some of the thoughts stop arriving. The ones that do arrive feel less urgent. My body, which has been broadcasting pain from my knees, goes quieter. Time stops being linear. Five minutes can feel like fifteen, or like two.

The last five minutes: genuine quiet. Not the zero-thought state the mystical framing promises — there are still thoughts. But they pass through without sticking. My chest unclenches. I become aware of small physical details: the breath, the floor, ambient sound. This is, I think, the part that ADHD brains rarely get to. We are usually too loud to notice we are in a body.

The bell rings, session ends. You try to stand up. Your legs remember they have been cross-legged for twenty minutes and briefly refuse to participate. I have come close to falling over more than once. This is normal and nobody judges you.

And then — the thing I keep coming back for — you walk out and the air feels different. Not magical. Just: the background hum has been muted. My head is quieter, my chest is lighter, and I can look at my inbox without the preemptive clench.

Twenty minutes. That's it.

Why it matters for dev work (especially if you have ADHD)

I don't want to claim zazen makes me a better engineer. That would be the kind of productivity-bro framing I actively avoid, and it's also not what's actually going on. What it does is more specific:

It gives me a hard context reset. Most of my job, corporate and after-hours, is multi-threaded. ADHD brains do not naturally release context between tasks — we carry every open thread with us, invisibly, taxing cognitive bandwidth. A zazen session is the closest thing I've found to running /clear on my own head. Not a break. Not a nap. An actual state reset.

It lowers the fake-urgency floor. The ADHD trap is that every stimulus feels equally urgent because the brain's priority-sorting is garbage. After a session, my nervous system stops treating every Slack ping and every side-project idea as DEFCON 1. I can triage more honestly for a few hours.

It's training in coming back. You sit down intending to focus. You immediately don't. You notice, you come back. You immediately don't again. You come back. This is, unexpectedly, the exact skill ADHD people need all day: notice the drift, come back, without shame. Zazen is literally structured practice in that move.

It builds tolerance for being still without feeling lazy. ADHD brains have a vicious internal narrator that equates stillness with failure. Practicing stillness in a structured, sanctioned, traditional context — where sitting still is the point, not the problem — slowly rewires that narrator. Sometimes the correct move on a hard problem is to close the laptop and sit. I used to fight this. Now I budget for it.

It's medication-friendly. I'm not going to tell you to replace anything with meditation. That's a personal decision between you and a medical professional. But zazen plays well with stimulant medication for me — it gives the medicated focus a quieter room to operate in. Your mileage may vary; please don't tweet at me.

How to actually go to a session

This is the part that feels intimidating and doesn't need to. You don't need to convert, become a monk, learn Japanese, or buy special clothes. You need to find a temple that runs a public zazenkai (zazen gathering) and show up.

If you're in Tokyo

Search 東京 座禅 初心者 or Tokyo zazen drop-in. Several major temples run weekly public sessions, usually early morning, often free or donation-based. A few practical notes:

• Large tourist-facing temples are your best bet for English support. If you don't speak Japanese, aim for temples that already host international visitors. They're used to beginners and will walk you through the mechanics (how to sit, how to bow, what the bells mean).
• Google Translate is fine. Bring a phone, use the camera feature on any written instructions. The monks running these sessions have seen every awkward-foreigner situation. They are kind about it.
• Smaller neighborhood temples often hold zazenkai too — they just don't advertise it in English. If there's a temple near your apartment, it's worth walking in on a weekday afternoon and asking. Many do, quietly.

If you're anywhere else

Good news: zazen is not a Tokyo thing. Zen traveled. There are Zen centers in New York, London, Berlin, Paris, Portland, Barcelona, and probably within an hour of wherever you live. Search [your city] zazen or [your city] Zen center. Most will have a weekly beginner-friendly drop-in.

They will usually have a fifteen-minute orientation before the session. They will show you how to sit. Nobody expects you to know what you're doing.

Logistics

• Loose, comfortable clothes. Something you can sit cross-legged in without a waistband cutting off circulation.
• Socks.
• Phone on silent, out of sight. Don't bring a notebook to "journal insights" — this is a thing people try and it misses the point.
• Eat something small an hour before. Don't go hungry, don't go full.
• Expect awkwardness the first time. Stay for the whole session. Leave better than you arrived.

The honest pitch for ADHD brains specifically

I'm not going to tell you this will fix your ADHD. It won't. What it will do is give you occasional access to a quality of quiet that ADHD brains don't get to often — and that quiet has downstream effects on how you code, how you triage, how you carry context, and how gently you talk to yourself during a bad focus day.

Twenty minutes is short enough that even the most restless ADHD brain can get through it with a trash-icon hack and some patience. It's structured, it's external, it's low-technology. You don't have to configure anything. You just sit.

If you try it, I'd genuinely love to hear how it goes for your brain. Drop me a note.

And if you don't — that's also fine. The cicadas are still loud somewhere.
