I had a class recently which got me to thinking about a favorite subject for many students - fans. Some studios and teachers use them a lot and some studios don't even use them at all. At Green Valley, we have some very nice and powerful fans and they are used quite differently depending on the teacher.
I have an interesting theory after watching the use fans. I'm convinced they don't do much to get people to do the postures if they're sitting out or about to sit out. I know sometimes teachers like to turn the fans on in the hopes that the people sitting out will go and do the posture. Unfortunately this seems to have mixed results at best. If you're at the point where you need to sit out, then a little bit of air doesn't make much difference. I know that on the rare occasion I need to sit out a posture, it has nothing to do with whether or not the fans are on. It's generally because of something like eating bad food earlier, being dehydrated before class, etc. So you can turn the fans on all you want, and I would still sit out. What's worse is that excessive fan use drives me crazy, dries up my sweat, makes me cold, etc.
I like a little air flow here and there, but any idea that it makes the postures more doable is a mental reaction, not physical.
