Stimming – short for “self-stimulatory behaviour” – is a common way for autistic people to self-soothe. It involves repetitive movements, sounds, or actions and is often categorised in medical literature as a form of “rigid and repetitive behaviour.” However, this framing can be misleading, as it casts stimming in a negative light. As a result, health professionals, teachers, and even parents may attempt to discourage it, despite its essential role as a self-regulation strategy. Suppressing stimming can have serious emotional and psychological consequences.

While stimming is not exclusive to autism, autistic individuals tend to engage in it more frequently and in more noticeable ways. Physical movements such as hand-flapping, rocking, spinning, or tiptoeing are common, as are repetitive interactions with objects like arranging them in patterns or using stim toys. Stimming can also involve other senses—some people find comfort in repeating words, scripting familiar conversations, or re-watching favourite films. Oral stimming, such as chewing on pens, clothing, or “chewllery,” is another common form. Many people, autistic or not, engage in stimming to some degree, yet autistic children are often encouraged to stop. Alternative suggestions, such as keeping hands in pockets, rarely provide the same sensory relief.
The act of suppressing stimming is an example of “masking,” where autistic individuals consciously or unconsciously hide their natural traits to avoid social judgement. Masking is particularly common among autistic women and has been linked to increased anxiety, burnout, and even suicide. Many autistic adults report losing their natural stims over time due to social pressure. In some cases, even workplaces discourage stimming, despite its benefits for self-regulation. Masking not only impacts mental health but can also affect education, employment, relationships, and overall quality of life.

Society must become more accepting of stimming, particularly parents, teachers, and employers. Research indicates that increased understanding fosters greater acceptance. Intervention should only be considered if stimming becomes self-injurious or poses a risk to others, in which case a safer alternative should be encouraged. Otherwise, the best approach is simple—let autistic people stim freely. If you see someone stimming, there is no need to comment or intervene. As the saying goes, “If you can’t say anything nice, don’t say anything at all.”
