Not sure if this 'new' theory has been posted here or not...

http://askakorean.blogspot.com/2009/01/fan-death-is-real.html

Quote:
Here is the science of how a fan could kill. Remember the conditions under which Fan Deaths happen � summer (=heat), enclosed room, fan directly on the body. An electric fan cools your body in two ways: by pushing cooler air onto your body, and by allowing your sweat to dry rapidly and take away heat in that process.

But clearly, the fan does not generate the cool air on its own, unlike an air conditioner. And eventually -- especially if you are a passed-out drunk who is already somewhat dehydrated from the alcohol -- your body will run out of water to turn into sweat. So what happens when it is very hot, but the entire room is enclosed such that no cool air comes in from outside, and you have no more sweat to cool your body with?

Basically, the entire room turns into a gigantic turbo oven. Turbo oven is a conventional oven that has a fan inside that continues to blow air onto the food. This oven is known to cook at lower temperature than a regular oven, yet cook more quickly. Similarly, in a heated room without an outside source of airflow, very hot air is constantly pushed directly to your body, which is a far more effective way of raising your body temperature rather than �baking� in hot air. If you get enough of this, you would die � of hyperthermia, or abnormally high body temperature.

So Korean people had it right after all � fans can kill. They just tend to give the wrong reason.


Read the rest if ya like.

Thoughts?

More than 50% of our body weight is water. That's hell of a lot of water to lose before you stop sweating.

Fighters such as boxers, wrestlers and mixed martial artists often cut tremendous amount of weight, sometimes about 10% of their body weight. Sometimes even to the point where they stop sweating. They sit in saunas and run on treadmills with giant plastic "sweatsuits" on for hours to sweat off the water weight.

There's no way a piddly little fan would accomplish this effect.

(Perhaps someone should tell these fighters a new and easy way to cut weight has been discoved. Simply sleep with the fan on!)

Pretty comical explanation...like the rest.

I've done the fan-death test on myself twice...once drunk, and once sober. I'm still living, but many Koreans tell me the reason I survived is that I'm not Korean.

Granted, I did the tests in our old house's bathroom. I also used a HUGE fan to make sure no one could attribute the use of a crappy, powerless fan to my survival.

As the bathroom door in our old place was warped, we got a pretty damned good seal going. PROBABLY not a TRUE vacuum, but even I wouldn't have been stupid enough, even while drunk, to put myself in an air(thus, oxygen)-free vacuum.

The other factor that I now have to reconsider is that I believe one of the tests was done in the winter, and maybe this newfound "hyperthermia" explanation is what saved my life?!?

Back to the lab...

Yeah, I'd be curious to know about how temperatures affect sweat rates. I imagine that there have been studies done in some hot climates somewhere.

If your body ran out of water you would die from dehydration not from the fan. That would happen anywhere your body runs out of water.. with or without a fan.

The 'scientific' tests I saw once on Korean TV to attempt to explain that Fan Death was possible were all centered on hypothermia.....not once was dehydration mentioned, AFAIK.

If Fan Death was plausible, and it was killing people every year, wouldn't one think the Korean scientists would have established a coherent explanation for it that could be understood by any other scientist?

Obviously, it's not going to kill a normal, healthy person like us.

You often hear stories of this or that country/city that has a heatwave in which x number of people die. Died from what exactly, and how to they make a causal link? I'm just saying it's possible Korea isn't the only country to use inexact science when reporting on heat related deaths.

I think the theory of the moving air causing the body to dehydrate to the point where the cooling mechanisms do not work so well is scientifically sound.

No one is claiming a 100% mortality rate from the fans, but if you are a septuagenarian alcoholic suffering through an intense heatwave a fan might very well kill you.

I'm sorry I don't get it. If you die from dehydration, you don't die because of the fan. If anything, the fan will keep you from sweating too much by cooling you even if you sweat a little.

Bottom line: If you are so dehydrated from drinking, you don't need the fan to kill you. The cause of death is alcohol related. You would be killed whether there was a fan or not. And, you would need to be really, really drunk to suffer this way.

I don't really understand the causality, though I am open to being explained.

And, I would think it would be really difficult to die from alcohol related dehydration, somewhat because I have never heard of anyone dying this way.

Why is it bad luck to walk under a ladder or cross the path of a black cat?


Or break a mirror?

1. Severe Hypothermia, which is where death occurs, starts when the body cools to 88F. No small fan on a person will cause this. The room would need to be in the 50's to cause immersion hypothermia(same as being under water).
2. If this was a legit cause of death, don't you think that the world would know about it and there would be signs posted about the dangers of leaving a fan on at night.
3. I explained to a Co-teacher that Fan death was bogus after she insisted it was real. She went home, researched it and came back next day and apologized saying once she actually looked at it, it didn't make any sense.
4. I can see how some sick,old frail person might get chilled overnight (such as winter time when people die from not having heating) and it cause them to shut down, but a normal healthy person would never succumb to this.

So, you're attacking me because...?
I read (yet another) theory about this topic and thought others might be interested in it and somehow that deserves an unoriginal swipe at me?

I think the point that the link is trying to make is that the fan will cause you to sweat more thus making it the/a main culprit in the death. Did you read the main point of it? I'm not supporting it, but his point goes against yours.

If you are in a room with extreme heat and humidity - how much will a fan cool you?

Fan death is Korean tradition. Korea is the only place in the world with four seasons and fan death!!!
