I’ve tried one session of traditional yoga that was conducted in an air-conditioning room.  I do feel weird about it as I hardly perspire at all.  As what I am aware of, most yoga outlet doesn’t equip their room with an air-contidioning.  The most they have is a rotating fan.  Does anyone know what is the actual norm for a yoga room?  I am in the midst of converting one of my room into a yoga room.  But the room has only air-con in it.  If air-con is a no-no, I have to quickly think of the alternative, i.e. to grab the discount ceiling fans that is on sale right now.
