Stimming (short for "self-stimulatory behavior") refers to repetitive physical movements, sounds, or activities that a person engages in, often unconsciously, to self-regulate emotions or sensory input. It is commonly associated with autism spectrum disorder (ASD) but can also occur in people with ADHD, anxiety, and other conditions. Everyone can engage in stimming behaviors, especially when stressed, excited, or overwhelmed.
Examples of stimming behaviors include:
- Hand flapping
- Rocking back and forth
- Tapping or repeating phrases
- Spinning or twirling objects
- Biting nails or picking skin
- Repetitive sounds or humming
Why do people stim?
- Sensory regulation: Some people stim to manage sensory overload or under-stimulation.
- Emotional regulation: Stimming can help regulate emotions like stress, anxiety, or excitement.
- Comfort and focus: Some find that repetitive movements help them focus or soothe themselves.
While stimming is often harmless, it can be socially misunderstood or, in some cases, cause harm if done excessively or aggressively. In these instances, alternative coping strategies may be explored.
