My 2 cents... I probably have AS, pending final diagnosis.
I dislike too much heat in enclosed spaces: at home, on a bus, in a car, where there is little or no airflow. Being on an overheated bus will add significantly to my anxiety and discomfort and might accelerate a sensory overload. However, I prefer hot weather over cold, and I mean I'd take 100F over 30F any time, but mean, open space.
I don't have that issue with hairdriers. A hairdrier doesn't bother me, as long as I am the one handling it: I dislike being touched by others, in particular on my head and face (I shave my head myself) and someone using hairdrier on me would count as "touching". However, space heaters (blowers) do bother me any time, in particular if they smell strange.
