What is stimming?
Stimming means self-stimulatory behaviour — repeated movements, sounds or actions that help a person regulate, express emotion or manage sensory input.
Examples: hand flapping, rocking, spinning, humming, finger movements, fidgeting, repeating sounds, tapping, chewing, watching lights, hair twirling, pacing, jumping.
The NHS notes that some autistic children may find repetitive movements calming and enjoyable.
Why people stim
To calm down, express excitement, manage anxiety, cope with sensory input, feel grounded, release energy, communicate feelings or focus attention.
Should stimming be stopped?
Usually, no. Stimming is often helpful. Only intervene if it is causing harm, is unsafe, is seriously affecting daily life, is causing injury, or the person wants help changing it.
If a stim is unsafe, try replacing it with a safer alternative rather than simply stopping it:
- Biting hands → chew-safe jewellery
- Head banging → crash mat, deep pressure, OT advice
- Scratching skin → fidget tool, textured fabric, stress ball
- Running off → safe movement space
