What's going on
In Japan, cleaning your ears with a small bamboo or metal ear pick (mimi-kaki) is a deeply familiar ritual — quite different from the cotton swab approach common elsewhere, and traditionally done while lying with your head in someone's lap. What most people don't experience is what one poster discovered: the act of cleaning their ears triggers an involuntary cough.
The culprit is a branch of the vagus nerve that passes through the outer ear canal. In some people, stimulating this nerve sends a confused signal to the throat, triggering a cough reflex as if something needed to be cleared. Estimates put this trait at around 2% of the population. When the original poster looked it up, they realized that the friend who'd said "yeah, me too!" on a call wasn't proof this was common — the two had simply found each other against enormous odds. The thread became a gathering point for the entire 2%, along with people sharing their own unexpected nerve cross-wirings.

I told someone on a call “cleaning your ears makes you cough, right?” and they said “yeah, totally~” so I figured it must be common lol. Turns out only 2% of all humans experience this. We’d just beaten crazy odds by finding each other. Regular people don’t choke when they clean their ears??
耳かきすると咳でるよね～って話をしたら通話相手から「わかる～」と返ってきたので多数派なんだと思ってニコニコしてたけどどうやらそんな人間全体の２%しかいないらしくただすごい確率で出会っただけだった。普通の人は耳かきしてむせないんだ。
I’m in the ear-cleaning-makes-me-cough camp too and always assumed it was normal. Then as a kid I saw a magazine Q&A where someone asked “why do I cough when I clean my ears?” and the reply was basically “huh? what? no idea lol” — that’s when I realized I was the weird one w
自分も耳かきしてむせる派で、コレが普通だと思ってたんですが、子供の頃購読してた雑誌の質問コーナーで「耳かきしてむせるのは何故？」って質問に対し「え？何それ…知らん」的な回答が載ってるのを見て、自分が少数派なんだと知った思い出w
Yep! I’m one of the humans that coughs 🙋
はい！咳が出るタイプのニンゲンです
Same here, I cough when I clean my ears. Genuinely surprised we’re the minority
自分も耳かきで咳出ます 少数派なのびっくりです
2%?! I’m absolutely the type who goes all wehho wehho when cleaning my ears — are there really that few of us??
2%！？私耳掃除でウェッホウェッホなるタイプだけど同士そんな少ししかいないの！？
My little sister always digs too deep and ends up choking herself lol
妹、よく深追いして咽せてる
Happens to me sometimes too. Mom’s the same way so maybe it’s hereditary?
ワイも時々だけどなるわ。かーちゃんもそうだからやっぱ遺伝なんすかね
Whether I use an ear pick or a cotton swab I always end up in a coughing fit. Honestly jealous of people who can just clean their ears like normal
耳かきでも綿棒でも咳が止まらなくなるから何も苦なく耳掃除できる人羨ましい
I cough when cleaning my ears too. And at this point I’ve figured out exactly which spot in my outer ear canal sets it off.
ぼくも耳かきしてると咳き込む。しかも外耳のどのあたりを刺激したら咳き込むかまで見つけてしまった。
For me it’s less a cough and more like… an itch in my throat
咳と言うか、喉がかゆくなる
When I do it myself it’s fine, but if someone else does it I cough like crazy. Was especially bad as a kid
自分でやる分には大丈夫なんだけど人にされるとめっちゃ咳出る 子供の頃とかヤバかった
Yeah!! My parents used to go at it without mercy and I’d be coughing the whole time
わかる！親が容赦ない耳かきするからめちゃくちゃ咳出てた
Left ear is totally fine but my right ear sets off a coughing fit every time!
左は平気なのに右だけめちゃ咳出ます！
Mine only triggers in the left ear
これ左耳だけなる
Left ear definitely sets it off! When I was little my grandma would clean my ears and point out every time that I’d cough. She’d say “just like your dad lol” — so yeah, probably genetic.
左耳をかくと確実に出ます！小さい頃祖母に耳かきをしてもらうと毎回咳が出ることを指摘され「お父さんにそっくり(笑)」なんて言われてたので遺伝要素がありそうです。
Right ear only for me
右だけ咳出るんよな
Started getting it in my right ear as an adult. My right ear canal seems smaller than the left — wonder if that’s related?
大人になってから右耳だけ咳が出る。右耳の穴が小さいっぽいが何か関係あるのだろうか
Is this some kind of vagus nerve reflex maybe?
迷走神経反射の一種とかなんだろうか
Apparently it is the vagus nerve. Not sure if it’s hereditary but both my parents and I cough from it. So when ear-cleaning cafes (specialty spots where attendants clean clients’ ears with a mimi-kaki — briefly trendy a few years back) were popular for a bit, I just couldn’t figure out how everyone else was perfectly fine in there.
迷走神経が原因らしいですね 遺伝するのかわからないですが我が家は親も私も咳き込みます なので少し前に流行った耳かき屋を見てなんで皆んな平気なんだろと思ってました
Happens to me too. Apparently there’s a nerve that connects the throat to the ear, and when stimulated it mistakenly reads the situation as something being in your throat. Also supposedly more common in women.
自分もなる 喉から耳まで繋がってる神経があるらしく、それが反応して喉に異物があると判定しちゃうのが原因らしい ちなみに女性の方がなりやすいらしい
I cough, and on top of that I get this feeling like my eyeballs are about to pop out… (I’m guessing the eyeball-popping sensation is probably a minority within the minority lol)
咳出ますし、なんなら目玉飛び出そうになりますね… （多分、目玉飛び出そうな感覚になるのは少数派）
No cough for me but my lower back goes all JOLT JOLT!! 😂
咳は出んけど腰がﾋﾞｸﾝｯﾋﾞｸﾝｯ!!ってなるわ
Oh I get you~ I cough when cleaning my ears, sneeze when I look at bright light like the sun, and scratching around my tailbone makes me suddenly need to pee
わかる〜 耳かきすると咳が出るし、太陽みたいな眩しい光を見るとくしゃみが出るし、尾骶骨のあたりを掻くとおしっこしたくなる
Same here. Also sneeze from bright light. And I’m apparently one of those people with no visible wrist tendon (recently went viral — people discovered that some individuals lack the palmaris longus, a thin tendon that shows as a raised ridge when you pinch your fingers and flex your wrist; roughly 10–15% of people don’t have it) either. I’m a rare species in all the most pointless ways.
私も出る。あの、光を見てくしゃみも出る。この前騒がれてい手首の骨も1本も出ないタイプなので、本当にめちゃくちゃどうでもいい所が希少種。
Never coughed from ear cleaning myself, but blowing my nose makes the spot between my eyebrows itch
耳かきでむせた事はないんですが、鼻をかむと眉間が痒くなります
Along the same lines — my husband sneezes from mint and other menthol-y things. When I told him that never happens to me he was genuinely shocked lol
似たような話でダンナ氏がミントとかスースーするものでくしゃみが出るという。私は全くそうならんて言ったらめっちゃ驚かれた(笑)
Slightly different but I have a spot on the right side of my upper lip that makes my right ear itch every single time I touch it. Human nerves probably don’t run in perfectly clean lines — maybe signals just get crossed sometimes.
ちょっと違うけど上唇の右側に「触ると絶対に右耳が痒くなる場所」があるので人の神経はあんまり綺麗な位置に通ってなくてたまに信号が混ざってたりするのかもしれないと思ったり。
I cry at a high rate when I 💩 but I’ve never once met anyone else like me
俺は💩するときに高確率で涙が出るんだけど、まだ同族に出会ったことがないんやね
Ear cleaning makes me cough, looking at the sun makes me sneeze, pulling three all-nighters makes blood come out of my butt, and pressing the handle of a wooden sword makes soy sauce come out
耳かきすると咳が出るし、太陽を見るとくしゃみが出るし、三徹するとケツから血が出るし、木刀の柄を押したら醤油が出る
There’s also the chance the person on the call was just going along with you. That might actually be how these misconceptions spread — where people who are really in the minority start believing they’re the norm.
通話相手も適当に話し合わせてるだけの可能性があるのが。こうやって、ほんとは少数派なのに自分が多数派だっていう勘違いが生まれていってるのかもしれない
My take
The way completely unrelated parts of your body turn out to be wired together by nerves — I feel like that happens more often than you'd think. The human body really is something else.
