A similar phenomenon makes it dangerous to sleep without proper ventilation:
>It is important that crew accommodations be well ventilated; otherwise, astronauts can wake up oxygen-deprived and gasping for air, because a bubble of their own exhaled carbon dioxide has formed around their heads.

- eridius 14y agoThis sounds like the exact opposite of fan death.
- lallysingh 14y agoBecause it's real?
- jere 14y agoThe funny part is fans mix gases and prevent exactly the scenario they're accused of causing in fan death (assuming we're talking about asphyxiation and not hypothermia... the hypothermia concern is beyond ridiculous). I don't think I've ever even heard of fan death, but I checked and the issue I mentioned in the OP is actually discussed on the fan death wikipedia page.
- hosay123 14y agoThis seems relevant.. old concrete can often emit significant levels of Radon that will tend toward floor level. It's supposedly quite important to properly vent old basements on a semiregular basis for this reason. In such an environment, a fan left running overnight may easily contribute to increased mortality.
- lifeisstillgood 14y agoMy first thought on reading "crew quarters must be well ventilated" was - like, opening the windows? Then I remembered. Luckily I am not on safety critical work for NASA
- Zecc 14y agoWhen I read "It is important that crew accommodations be well ventilated; otherwise, astronauts can wake up ..." my mind completed with "asphyxiating in a vacuum".
