Why Stimming Is Not a Problem — And Why We Need to Stop Treating It Like One

My stims regulate my nervous system. They are not a behavior to be fixed. They are part of how I function.

I was eight years old the first time someone told me to stop.

I had been rocking slightly in my chair — a gentle, rhythmic movement that I was barely aware of. The teacher called my name. I looked up. "Can you please sit still?"

I sat still. For the rest of that class, and for many classes after, I monitored my body constantly for movement that might draw attention. Hands flat. Back straight. Still.

I did not know then what I know now: the rocking was helping me think. It was giving my proprioceptive system enough input to let my mind focus. Stopping it did not make me calmer or more attentive. It redirected cognitive resources toward monitoring my body, leaving fewer resources for what I was supposed to be learning.

Stimming — self-stimulatory behavior — is the body's way of regulating the nervous system. Rocking, hand-flapping, humming, spinning, chewing, repeating sounds or words, rearranging objects: these are the ways an autistic nervous system manages sensory input and emotional arousal. They serve a real neurological function.

The research is clear on this. Studies show that suppressing stims is associated with increased anxiety, reduced cognitive performance, and greater risk of burnout. The behavior management approaches that were standard practice for decades — including intensive ABA focused on eliminating stims — were addressing the visible output while ignoring the underlying need. The need does not go away because the outlet is blocked.

I stim less visibly now than I did as a child — not because I was trained out of it, but because I found stims that work for me in adult environments. I have fidgets in my desk. I work from home when possible, which means I can rock, pace, or hum without managing other people's reactions. When I cannot avoid an environment that requires stillness, I feel the difference.

Here is what suppressing stims costs: attention. Focus. Emotional regulation. By the end of a day where I cannot stim, I am significantly less functional than I would otherwise be. The energy that would have gone toward the work went toward the performance of stillness.

The question I would ask parents and educators who want to reduce stimming is: what need does it meet? Because that need does not disappear when you suppress the behavior. It finds another outlet — sometimes more disruptive, sometimes internalized in ways that are invisible and harmful.

The more useful question is not "how do I stop this" but "how can I give this child the sensory input they need in a way that works for everyone."

Weighted blankets. Fidget tools. Movement breaks. Seating options that allow more body movement. Chewable jewelry. White noise or music. Dedicated time to move.

These are not rewards. They are access. They are how autistic people function.

My stims are part of how I think. They are not a disorder to be treated. They are adaptations developed by a nervous system trying to work as well as it can in an environment that was not designed for it.

The problem was never the rocking.
