Do not point at face while sleeping. Must open all windows. Will cause DEATH)
I interrupt the silence to bring you none other than "Korean Fan Death". This is a REAL and SERIOUS issue folks. Tens of Koreans die every year because of fans....(Yes, I am talking about those oscillating machines that keep us cool on hot days.)
This is taken from wikipedia.org Fan Death
South Korean government position:
The Korea Consumer Protection Board (KCPB), a South Korean government-funded public agency, issued a consumer safety alert in 2006 warning that "asphyxiation from electric fans and air conditioners" was among South Korea's five most common seasonal summer accidents or injuries, according to data they collected. Also included among the five hazards were air conditioner explosions, and sanitation issues, including food poisoning and opportunistic pathogens harbored in air conditioners. According to the KCPB:
"If bodies are exposed to electric fans or air conditioners for too long, it causes bodies to lose water and [causes] hypothermia. If directly in contact with [air current from] a fan, this could lead to death from [the] increase of carbon dioxide saturation concentration and decrease of oxygen concentration. The risks are higher for the elderly and patients with respiratory problems. From 2003 [to] 2005, a total of 20 cases were reported through the CISS involving asphyxiations caused by leaving electric fans and air conditioners on while sleeping. To prevent asphyxiation, timers should be set, wind direction should be rotated and doors should be left open."
