In July 1973, the South Korean police found a man dead in his room. The doors and windows of the room were closed and there were no signs of outsiders entering. When he was found, only two electric fans were still spinning. The
incident caused great panic in Korean society. People believed that the electric fan killed the man, which was called the electric fan murderer. The subsequent investigation results of the case further confirmed this speculation.
Korean society has fallen into this fear for a while.
The Global Times reporter in South Korea used to go to the supermarket to buy electric fans because he couldn't stand the summer heat and didn't like to use the air conditioner. I thought that the temperature was so high that electric fans would be out of stock, but after arriving at the supermarket, I found that many electric fans were actually on sale. When the reporter was buying an electric fan, the salesperson aunt also reminded her that the room must not be closed at night, and the electric fan must not be turned on all night, otherwise it may be life-threatening.
Coincidentally, there was a Korean friend who had been told by her parents about the murder of electric fans since she was a child. Although she was dubious, she still had an instinctive fear of electric fans. One year when traveling to Southeast Asia, the temperature was very high and the night was very sultry, but she preferred to sleep in the corridor instead of blowing an electric fan in the house.
Some people don’t believe this statement. They think that in a closed room at night, when the wind blown by an electric fan blows directly on the surface of the human body, the airflow will drive the air to reduce the pressure near the body, resulting in a decrease in the oxygen content in the air. At the same time, human body temperature will drop.
If the wind of the fan is strong enough, people will have short-term breathing difficulties due to insufficient oxygen, and a drop in body temperature will also make it difficult for people in sleep to wake up.
At the same time, people in a closed room continue to exhale carbon dioxide, causing the oxygen content in the room to further decrease, and eventually people will gradually suffocate due to lack of oxygen in a coma.
seems reasonable. However, medical research has found that electric fans need to blow for three days and three nights to reduce body temperature. On the other hand, it is difficult to lower the air pressure only by the weak wind of electric fans.
Therefore, there has not been an authoritative enough convincing statement about the electric fan murder, but this kind of fear really persists in the psychology of the Koreans.
In 2006, the Korean Consumer Council also listed "electric fan killing" as one of the five most dangerous things in the summer".
