Definition:
Fan death is a South Korean urban legend which states that an electric fan, if left running overnight in a closed room, can result in the death (by suffocation when oxygen is "stolen" from the victims, poisoning, or hypothermia) of those inside.
Causes:
Fan death is thought to be caused by an electric fan left om overnight. Fan death is also thought to be caused by air conditioners and fans in cars, which is why some Koreans leave their car windows open a crack to avoid this unpleasant death, though not often enough, as evidenced by the surge in deaths caused by fans.
