Definition
Stimming, short for self-stimulatory behavior, refers to repetitive movements, sounds, or sensory input that help regulate the nervous system. Common stims include hand-flapping, rocking, humming, spinning, chewing, or repeating phrases.
Why It Matters
Stimming serves a genuine neurological function: it helps autistic people manage sensory input, regulate emotions, and communicate. Suppressing stims is harmful and linked to increased anxiety.
Common Misconception
Stimming is not a symptom to eliminate. It is not inherently disruptive. Many non-autistic people stim too, leg-bouncing, hair-twirling, pen-clicking, but autistic stims are more visible and more frequently targeted for suppression.
