I'm very curious if anyone knows any neurologic explanation of why stimming is linked to Asperger's, or why it works.
I can't remember where I read it (probably here on WP) but I remember reading somewhere that there was a theory linking stimming to the production of endorphins, the "feel good" hormones. I can't remember if this was an ASD-specific thing or just a general neurological theory. I hope someone more knowledgeable than I can provide better information.
I know of one thing I am certain is a stim. I like to run my hair between my index and middle fingers, mostly with my left hand. I did it as a kid and remembered that I felt so much pleasure from it. I remember doing it so much my parents would yell at me. I got the impression it was "wrong." As an adult I decided to go to a buzzcut mostly because it was low maintenance but also to minimize this stim (though I didn't know what it was at the time). That was 14 or 15 years ago. In that time I occassionally found myself rubbing my hair with my hand, but it wasn't quite as satisfying so I didn't do it very often. Since my AS diagnosis last month I decided to let my hair grow out so I can start doing it again. One of the reasons I sought out the diagnosis was to find out why I was having meltdowns and learn to better handle the stress that leads up to them. Once I learned what stimming was and what its purpose was, I realized I did it as a kid to soothe myself. Now, with my hair noticeably longer, I can now do this stim again. However, I've found I do it nearly all the time, often without knowing I'm doing it, unless I'm focusing on a task or doing something that requires both hands. I really start going crazy with it if my hair is wet or cool to the touch. It looks weird, particularly at work, but I haven't been feeling as stressed as before or, more importantly, meltdown-prone since I've started, so I'm sticking with it.
I do a few other things that I've heard were stims, but they're more boredom/fidgety-related. Several months ago I realized I had started doing this thing with my left hand where I bend my thumb and then tap the top of it with my index, middle, and ring fingers in a rhythmic pattern. If you've seen the movie "Ben X" it looks similar to what he does with his right hand when he walks down the street. When I first noticed it I thought it was my mind subconsciously trying to play guitar since I haven't played in a while. I also have a tendency to pace a lot, at work and at home. Sometimes when I'm at home I play with a yo-yo, though I don't do any tricks; I just make it go up and down. It's relaxing for some reason.
Hmm...over-explanation?
