This is no more odd than my mother’s family’s belief that sleeping in front of a fan causes illness & stiff muscles.

Is your mom’s family Russian or Eastern European?

My parents believe that 'air draught' can cause the common cold. It was considered pseudo science in the 1960-1990s, and largely ignored by Medicine. As it turns out, draught and cold makes you more receptive to the virus. (I guess that's where it got its name from)

Are you dutch by any chance? I spend hours in the back of my grandparent's car driving through Germany, sweating and being miserable because my grandfather "would get a stiff neck from the air draft". I never believed it.

TeMPOraL2• 8 years ago

Yeah, in Poland, it seems all my family from my parents' generation and older believe in that too. As a kid, I had endless battles with all of them over opening a window. E.g. it would be too hot for me, but everyone would say, "close the window, there's a draft and it'll get you sick". smh.

"Stiff neck" 'teekert mentions and "ear pain" would be mentioned as dangers of draft too. It's so pervasive in the local culture that I even have to occasionally remind people from my generation that common cold is a virus, not a side effect of exposure to elements.

And since my roommate in Japan fell asleep in front of an air conditioning and woke up with a severe bronchitis, I know that falling asleep in front of an AC isn't the best idea either. Luckily I was suffering from severe diarrhea at the same time, so we both had something to make fun of each other. Although his laughter sounded a bit weird due to the bronchitis.

teekert5• 8 years ago

No offense but basing the conclusion that sleeping in front of an AC causes bronchitis on a single observation is the way to help such misunderstandings into the wild.

In reality, you need a fan in an enclosed space to prevent death—at least in zero-G.

I had heard that it was a way to report on suicides without needing to specify how they died.

djsumdog2• 8 years ago

That seems plausible.

kbumsik2• 8 years ago

As a Korean it is funny to see this in HN. And yes, almost everyone used to believe this so that my parents always taught me turning off the fan before sleeping. This psudo-theory is so widespread that it is used to assassinate someone in fictions.

wishinghand3• 8 years ago

Years ago I first took the Wikipedia article at face value. Later on I thought to myself that it’s too far fetched for a majority of people to believe in it. I had also heard that maybe it started as a euphemism for someone who had committed suicide and caught on. Can you shed any light on how common it is? Is it something that people with less education tend to believe?

rubatuga2• 8 years ago

These are just some of my thoughts. Even my parents used to believe in fan death, and both my father and mother are very well educated. My father has a PhD, and my mother has a Masters.

The younger generation don't believe in fan death anymore. Still, many of the older Koreans that believe in fan death are very well educated. However, talking to my parents, they were not educated to think critically, and even today that is not a value that is stressed in Korea. Essentially the majority of older Koreans were raised in a society which had dictatorships, coup d'etat, assassinations, censorship, and government controlled media. Koreans had great economic success, but less freedoms, similar to the situation in China today. Questioning the status quo is detrimental, and keeping your mouth shut is a virtue still taught in Korea today. Knowledge such as fan death is just accepted as fact, and it stayed engrained until recently.

chalupa-man• 8 years ago

It is generational, rather than tied to education. Even very well-educated Koreans born before around 1980 tend to believe in this. I would say it is close to 100% of people over 40. My parents, grandparents, aunts and uncles would call you stupid for not believing in it. My doctor believed in it. Younger people believe in it less often but it is still very common.

Simulacra2• 8 years ago

The fiction sounds interesting! Do you have a reference?

kbumsik2• 8 years ago

I saw some mangas do it, copy and paste "선풍기 살인" in Google image search. They are often referenced as the most perfect assassination in the Korean web to make fun of the ignorance of the authors.

Fun story:

A few years ago I was backpacking around Asia met some friends in northern Vietnam. We were 6 or 7 people so we just rented out a dorm room in a hostel. There were 2 beds left, which were later filled by 2 Koreans.

That night we were all hanging out and the Koreans were quietly minding their own business. It was pretty hot, as Vietnam usually is, so we had the ceiling fans going strong.

Just before turning out the lights, I bent down to the lower bunk and asked if it was ok to turn them off and leave the fan on. I get a mostly blank stare as he murmured a word or two. It didn't sound likely anything close to a "no" do I smiled and said goodnight!

Fast forward to breakfast the next morning, and we're talking about our sleep and someone asks if we heard what they said before turning off the lights. Turns out it was "fan death." Most of us hadn't heard of it before.

Poor guys probably didn't sleep all night.

acchow• 8 years ago

Why didn't they just keep a window or door open too?

reustle2• 8 years ago

1) There were no windows in that room

2) Never leave a bedroom window open in SE Asia, unless you love mosquito bites

lordnacho• 8 years ago

My father is the oldest of a very large bunch of kids. When I ask him to count my aunts and uncles, he always mentions one who died as an infant.

And guess what the "cause" was? Now I understand it better, I always wondered WTF he meant when he said someone left a fan on in the baby's room.

djsumdog2• 8 years ago

Moldovans believe you can get sick from leaving a window open and the breeze coming in. You can be on a packed, sticky hot microbus and they will not crack open a window.

I don't think this superstition is specific to Eastern Europe because I've heard some Germans state similar things about leaving windows open and getting sick.

jacobush3• 8 years ago

Sweden: my mother, my aunts, grandparents on both sides etc. This goes mostly for cars. The thing about opening windows in a house is a bit more hit and miss.

vaibhavsagar• 8 years ago

There's a variant of this in Indonesia too: http://www.expat.or.id/medical/masukangin.html

teekert5• 8 years ago

I think we have some of these things in the Netherlands as well, people believe (among others):

* Air draft causes a stiff neck

* Freezing meat twice and eating it will make you sick

* Cold in general will make you sick ("catch a cold")

* If you hold your poo to long, you can never poo (well) anymore (from the grandparents, pretty sure they believed it, actually it may be true to a certain degree but they used to go when one need to go asap.)

I'm sure I'll come up with more.

DanBC• 8 years ago

* Freezing meat twice and eating it will make you sick

That's not unreasonable. There are different ways to give the safety advice:

1) Don't do it. https://www.nhs.uk/live-well/eat-well/how-to-store-food-and-...

2) It's fine so long as the meat defrosted in the fridge, and your fridge is keeping the correct temperature. Don't re-freeze meat kept out of the refridgerator for longer than 2 hours. https://food.unl.edu/it-safe-refreeze-raw-meat-and-poultry-h...

Sometimes the simpler message is safer.

* Freezing meat twice and eating it will make you sick

Uh, every frozen meal I have ever seen has come with the printed warning not to freeze it again after it has melted?

Freezing does not kill microbes, and additionally formation of ice during the freezing breaks the internal structure of foodstuff making it better medium for bacterial growth. So repeated freezing-unfreezing, especially if the product is taken into room temperature and back allows unwelcome microbes to proliferate. Like with all food poisoning hazards, it will not make you sick with 100% certainty, but increases the risk enough that it is not recommended.

This is near word-by-word translation of the guidelines of Finnish medical society [1] and food safety authority [2].

It is difficult to call "do not freeze stuff again" an unfounded superstition equal to fan death if it is the common recommendation by national authorities.

Ok I didn't consider the "makes meat more permeable to bacteria" -argument. Still, bacteria do die from repeated freeze-thawing cycles. But, in any case, I doubt many people ever investigated the scientific evidence.

coldtea2• 8 years ago

Freezing meat twice and eating it will make you sick*

It won't necessarily make you sick, but it will have much more bacteria after been thawed (the same bacteria it had frozen, but now reproducing again during the time the meat is in normal temperature before getting frozen a second time)

This makes me think of all those pre 1960 American films where someone gets wet in the rain, then at best gets a cold, at worst gets a fever and dies.

I believe its quite common in southern Europe to believe that swimming after eating will lead to stomach cramps and drowning.

I'm surprised to hear the eastern European thing about breezes etc. It was quite common in western Europe and America to open windows even in winter for sleeping children, I believe the practice is still common in scandinavian countries.

jacobush3• 8 years ago

Anecdata for Sweden - yes for me. Some people even let their babies nap (well tucked in) in the stroller in the winter.

Double_a_92• 8 years ago

its quite common in southern Europe to believe that swimming after eating will lead to stomach cramps and drowning.

Taking a bath and showering too...

benj1112• 8 years ago

How does that work? I thought the fear was you wouldn't be able to swim due to cramps, and drown. That isn't really a concern in the shower. And you aren't really using the same (or any) muscles in the shower, to risk a cramp anyway.

dredds• 8 years ago

"Yohan Yoon noticed that his Korean-American parents kept opening the door to his room whenever he slept with the fan on.. So what’s behind this superstition and what role does culture play?"

Another interesting aspect about Fan Death is Hacker News obsession with this subject. There have been been about 15 stories on Hacker News about this so far.

wishinghand3• 8 years ago

Well if it's over several years that's fine. It's an interesting oddity and I'm sure the readership changes over time as well, making it new to plenty of readers.

Simulacra2• 8 years ago

Oh wow I can't sleep without a fan. I stayed at a hotel in Berlin with no a/c or blower option and I had a terrible nights' sleep. The follow year when I went back to that hotel, they had a fan waiting for me. Bless them. I even travel with a USB powered fan on airplanes, because those little nozzles of recycled farts they keep moving further away just won't cut it.
