aromatherapy on closed doors

[ianvillacrusis]

is it dangerous to burn fragrant oils when inside an airconditioned room? or enclosed spaces, we do that almost everynight

[Minyassa]

I would think it would depend upon the oil and amount.  When I go through a period of insomnia I will put a sleep aid blend in my diffuser in the bedroom, which is pretty small, and keep the door closed.  I also burn stick incense in my closed room and only occasionally have problems with it making me cough if I either burn too many sticks in succession or if I am trying a new brand and it contains artificial fragrances.
