    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.
