This is not very scientific of course but they also measured the subjects' body oxygen and temperature levels and found that the oxygen didn't go to a level where it was harmful, and body temperatures didn't drop to a level where hypothermia would set in and kill the sleeping victim. If these notions sound bizarre, that's the power of Korean urban legend for you. The results:
|body oxygen||sleep efficacy||body temperature|
In other words, fans don't use up the oxygen in a closed room, the air isn't sucked away from under the nose causing suffocation(!), and body temperatures don't plummet to dangerous levels. Korean Mother says she's not yet convinced, but we're going to show her the video next time she comes round to see if the KBS report can change her mind.
Of course, three people is hardly a scientific sample size, and a fairer study would no doubt involve more people, more time, and certainly more soju to accurately reflect the realities of life in Korea.
Intriguingly, I read that the notion of 'fan death' really gained traction in public mind around the time of the energy crises in the 1970s. If true, one wonders if this didn't play into the hands of a government trying to manage supply, if indeed there wasn't deeper involvement in its creation.
