I've had it up to here with yoga studios and certain teachers. Why are they so insistent about being "authentic" about burning incense when it affects so many people, e.g. asthma, people who get migraines, and people who just straightforward hate the smell? The same goes for "smudging" products (for "cleansing the space" 
), palo santo, and scented oil burners etc. Just stop burning stuff FFS! I can't breathe properly, and now my hair stinks and I need to wash it again. Why are people in so much denial about how harmful it is?
I've been trying to find out about the type of local yoga classes that take place at local community centres, dance studios and hired halls etc, even the teacher's house like I used to do until my teacher had a career change. I wish their smoke policy could be listed online so I didn't have to keep emailing people. Recently I received yet another reply from a teacher saying she does burn incense, but she could stop if it really affected me, and that she was grateful for my communication.
Except that this has happened several times before, and every single time without fail they have stopped for a couple of weeks and then started again as if I wouldn't notice. Because however grateful they claim to be, really they're secretly annoyed that someone has asked them to change something about their class. That's why I'm looking for a class where they don't burn anything in the first place, so that I don't have to keep making special requests.
I've also tried various other spiritual things like 5 Rhythms (silly I know) and the organisers are just as bad and I often end up feeling stressed and annoyed.
I also used to go to a music rehearsal in a multi-purpose building where the timetable got changed and the booking before us was given to a yoga class, so even after they'd left, the room still stank. We made complaints to the manager of the building and all they could do was tell us to open the windows, even in the middle of winter.
It's just not good enough.
