Electric fans can kill you overnight in South Korea

CULTURAL BELIEF, NOT A LAW. While not illegal, some Korean fans are sold with automatic shut-off timers, and safety warnings have appeared on fan packaging.

The Full Story

The Belief: Running an electric fan in a closed room overnight can cause death by hypothermia or asphyxiation.

Legal Impact: While not illegal, some Korean fans are sold with automatic shut-off timers, and safety warnings have appeared on fan packaging.

Scientific Consensus: There is no evidence that fans can cause death in this manner. The belief is considered a cultural phenomenon, possibly originating from government messaging during 1970s energy crises to reduce electricity consumption.

Why Include This: It illustrates how cultural beliefs that seem "law-like" can spread and become treated as fact, even without actual legislation - relevant to understanding how weird law myths propagate.

Common Misconceptions

Many people outside Korea assume fan death is an obscure law or government regulation, when it is actually a cultural superstition with no legal basis. While the South Korean media has reported fan-related deaths, medical experts attribute these to other causes such as heat stroke or pre-existing conditions. The belief has significantly declined since the 2000s due to internet skepticism.

Actual Legal Text

Fan death is not a law but a widespread cultural belief in South Korea dating back to the 1920s, when newspapers first warned of risks from electric fans. The belief holds that sleeping in a closed room with a running electric fan can cause death by hypothermia or asphyxiation. No scientific evidence supports this claim. Korean electric fan manufacturers responded to the belief by including automatic shut-off timers on fans sold domestically.
