The sources reviewed here do not establish that ordinary fan use kills a healthy person in a closed room. A household fan does not remove oxygen or create a vacuum. The Korean fan death story is a cultural belief, separate from real heat, electrical, or other medical risks. Warnings about electric fans appear in a Korean newspaper archive entry from 1927, decades before the often-repeated 1970s energy-crisis theory. That entry shows concern about fans in print by then; it does not establish when the specific enclosed-room death legend began or reveal a single origin.
“Fan death” refers to a reported Korean belief that sleeping with an electric fan running in an enclosed room can be fatal. Historical reporting documents the belief, but reports and expert interviews do not establish that ordinary fan use causes such deaths. Heat, electrical, and other medical risks are separate questions.
What does the historical record show?
The National Institute of Korean History catalogues a July 31, 1927 article in Joongoe Ilbo titled “선풍기병, 신기하다는 전기부채의 해, 잘못되면 생명 위험,” roughly, “Electric-fan sickness: the strange harm of fans, potentially life-threatening if misused.” The archive identifies it as a commentary or opinion piece. It is evidence that warnings about fans appeared in print during the 1920s, not evidence that the warning was medically correct or that the article began the belief.
That date also complicates the popular claim that a South Korean government invented fan death during the 1970s energy crisis to reduce electricity use. Warnings about fan-related illness appeared in print by 1927, so the 1970s cannot be the first time fans were linked with serious danger in Korean public writing. The archive entry alone cannot establish whether it described the same enclosed-room death legend. The sources reviewed here do not establish who first circulated the idea or whether later officials deliberately promoted it.
Newspaper reporting continued to describe people found dead with fans running. A 2004 Korea JoongAng Daily review of newspaper archives found such stories from the early 1970s onward and interviewed forensic and medical experts. The article records disagreement among those experts at the time; it does not demonstrate that a fan caused the deaths. A later 2026 account by Stripes Korea likewise describes the origin as unclear and distinguishes the older belief from the unproven government-origin theory.
Can a fan use up the oxygen in a room?
No. A household fan moves air around the room; its blades do not consume oxygen, break oxygen molecules, or make a vacuum over a sleeper. The 1927 newspaper article is a historical source for a warning that appeared in print, not scientific evidence that the warning was medically correct.
Reports of a death occurring while a fan was running also do not, by themselves, show that the fan caused it. In its 2004 reporting, Korea JoongAng Daily quoted a Seoul National University forensic-medicine professor who had examined some cases and said that underlying conditions were present in many of them. The same article records differing professional views, so it should be read as a report on a debate, not as a controlled study. Yonhap’s 2008 interviews also captured disagreement among Korean physicians. Neither a newspaper headline nor an interview can determine the cause of an individual death without medical evidence.
Is there a real safety concern when using a fan?
Yes, but it is different from oxygen deprivation. A fan does not cool the air in a room the way air conditioning does. It can help a person feel cooler by moving air across the skin, but very hot indoor air can change that effect. The U.S. Centers for Disease Control and Prevention advises using fans indoors only when the temperature is below 90°F (about 32°C); above that, a fan can increase body temperature.
That heat guidance concerns overheating, not the traditional claim that a fan removes oxygen or creates a lethal vacuum. Follow local heat alerts, drink fluids as appropriate, and move to a cooler place when indoor temperatures are dangerously high. Use electrical appliances according to their safety instructions and keep damaged cords or motors out of service.
Do people in Korea still believe in fan death?
Views differ by person and generation. A 2026 first-person report in Stripes Korea describes the warning as a family habit the author heard growing up, while also noting that the story’s history is uncertain. One person’s account cannot measure how common the belief is nationwide. It is safer to describe fan death as a recognizable Korean urban legend without suggesting that all Koreans believe it.

Sources and scope
The historical date and headline come from the National Institute of Korean History’s record of the 1927 Joongoe Ilbo article. Contemporary expert views and newspaper-archive reporting are summarized in Korea JoongAng Daily (2004) and Yonhap (2008). Current fan-use heat guidance is from the CDC. A 2026 Stripes Korea account provides a recent, attributed perspective on the belief. These sources support a cautious history and a distinction between folklore and heat safety; they do not establish a definitive origin or a prevalence rate.
