Fan Death: The Terror of Closed Rooms and Electric Fans

If you grew up in a Korean household, you probably remember the sheer panic of a hot summer night being abruptly interrupted. Picture this: It’s July, the humidity is unbearable, and you’ve finally drifted off to sleep with a fan oscillating peacefully beside your bed. Suddenly, your bedroom door flies open. Your mother rushes in, dramatically clicks off the fan, and cracks the window open. "Do you want to die?" she scolds in a hushed, terrified whisper.

Welcome to the phenomenon of "Fan Death" (선풍기 괴담)—one of Korea’s most infamous and enduring urban legends. For decades, it was a widely accepted fact across the Korean peninsula that sleeping in a completely closed room with an electric fan running would lead to certain death.

The supposed scientific explanations varied, depending on who was warning you. Some claimed the fan would create a vortex that sucked the oxygen away from your face, causing asphyxiation. Others insisted it would drop your body temperature to fatal levels of hypothermia. Some even believed the fan blades physically chopped up the oxygen molecules. To a non-Korean, this sounds like a plot from a sci-fi comedy. But in Korea, this belief was so pervasive that to this day, almost every electric fan sold in the country comes with a mandatory built-in sleep timer. You wind it up to 60 or 120 minutes, ensuring the machine shuts off before it can supposedly claim your life.

But where did this deeply rooted fear come from? As a Korean-Canadian, I always found it fascinating how my parents, who were otherwise perfectly logical immigrants, held onto this belief with ironclad conviction. The roots of the Fan Death myth can actually be traced back to Korea's rapid modernization in the 1970s.

During this era, South Korea was facing a severe energy crisis. Electric fans were becoming a common household appliance, causing power grids to strain. Rumor has it that the government—aided by sensationalist media—either birthed or conveniently leaned into the myth to encourage energy conservation. Nightly news broadcasts would occasionally report on a tragedy: a person found dead in their home. The actual cause of death might have been a heart attack or alcohol poisoning, but the news anchors would point out the ominous detail: "An electric fan was found running in the closed room." In an era before the internet, if the 9 o'clock news said a fan could kill you, it was treated as absolute gospel.

Today, the Fan Death myth has lost much of its lethal grip. Younger millennials and Gen Z Koreans, both in Korea and across the diaspora, openly joke about it. We make memes about surviving a night with the fan on. Yet, the legacy remains embedded in our culture.

Even now, when the summer heat rolls in and I turn my fan on before bed, I catch myself subconsciously leaving the bedroom door open just a crack. It’s no longer about a genuine fear of suffocating. Instead, it’s a lingering echo of my mother’s voice—a quirky, slightly overbearing, but undeniably warm expression of Korean parental love, making sure I survive the night.
