South Korea Has Fan Death Belief

In South Korea, it's standard for electric fans to come equipped with automatic timers, a feature directly linked to a persistent and uniquely Korean urban legend. The widespread belief is that if you fall asleep in a sealed room with a fan running, you risk death. The supposed mechanisms for this "fan death" vary, with the most common explanations being suffocation from depleted oxygen or a fatal drop in body temperature, also known as hypothermia.

While scientifically unfounded—as fans only circulate existing air and cannot lower a room's temperature—the myth has plausible historical roots. One prominent theory traces its origin to a 1970s government media campaign. During a national energy crisis, reports on the dangers of leaving fans on overnight may have been promoted as a way to encourage citizens to conserve electricity. Another theory suggests the belief grew from early, unscientific media reports that sensationalized coincidental deaths, linking the tragedy to the fan that happened to be in the room without considering other causes like heat stroke or underlying health issues.

Despite a lack of evidence and skepticism from younger generations, the notion of fan death has shown remarkable staying power. It remains a common piece of household advice passed down from elders, and the ubiquitous timer feature on Korean fans serves as a tangible daily reminder of this fascinating cultural belief.
