    A superstition that fans must not be left running constantly.

    Trains in Korea periodically restart the air conditioners in the cars to say that they weren’t constantly running.

      It’s that you can’t sleep with a fan on in an enclosed room with no open windows. Thats the murdery bit.

      A constantly running fan isn’t a problem there as far as I know.

        if you were in a room with no ventilation (ie shut and sealed windows, a door with an air seal and no air vents)

        • in zero gravity
        • OR in a room with a heat index of 90°F+ (heat index not temperature)
        • OR in a room that puts you in danger of hypothermia (especially if you have heart issues at the same time

        it’s possible that a fan might exacerbate oxygen deprivation or the affects of the extreme temperatures

        If you have normal windows, a gap under the door and a vent of some kind then it simply won’t.

      Locked in a house with a killer fan that has a mind of its’ own!

      Ma’am, we’ve traced and located the source of that breeze, it seems to be coming from…
