What Is Stimming

Stimming, short for "self-stimulatory behavior" or stereotypic movement, refers to repetitive physical movements, sounds, or behaviors—such as hand flapping, rocking, or spinning—common in individuals with autism. These behaviors serve as essential coping mechanisms for regulating emotions, managing sensory input (avoiding overload or seeking stimulation), reducing anxiety, and aiding focus. 

People with autism stim to help them self-regulate. It can be anything from rocking back and forth, spinning in circles, walking on their toes. There are also vocal stims like humming, repeating words or sounds. A lot of stims are harmless, but there are some that are hurt like head banging or biting. 

Stimming can help manage emotions, sensory input and stress. Stimming can be visual, auditory, tactile, or motor-based, helping individuals cope with overwhelming environments. Look at it as a way for someone to help us feel comfortable with being in uncomfortable situations. 

Common Motor Stimming (Body Movement)

• Hand Flapping: Frequently used when excited or distressed.

• Rocking: Moving back and forth while sitting or standing.

• Spinning: Turning in circles.

• Pacing or walking on tiptoes.

• Head banging or tapping.

• Twirling hair or fingers. 

  
  

Visual Stimming (Sight-Based)

• Watching objects spin: Staring at fans or spinning toys.

• Repetitive blinking.

• Flicking fingers in front of eyes.

• Staring at lights or colors.

  
  

Auditory/Vocal Stimming (Sound-Based) 

• Echolalia: Repeating words, phrases, or movie lines.

• Humming or grunting.

• Whistling.

• Tapping ears or making clicking noises.

  
  

Tactile/Sensory Stimming (Touch/Taste/Smell) 

• Rubbing textures: Stroking soft fabrics or skin.

• Chewing or mouthing objects.

• Sniffing objects.

• Scratching skin. 

  
  

Object-Focused Stimming

• Flicking switches or opening/closing doors.

• Fidgeting: Tapping pencils or spinning items.

Stimming is generally harmless and helps regulate the nervous system, but it may require support if it becomes self-injurious, such as severe scratching or head banging.

I’ve noticed I have a few stims that I didn’t know what they were until I learnt what stimming was. They are most common when I’m walking. I’ll be listening to music and I will I tap my fingers along with the beat to whatever song I’m listening to. I also tend to stick my arms out when I’m walking. If my sweatshirt has long sleeves, I twirl the ends as I'm walking.

I remember I used to spin when I was a kid. It didn’t happen often since it only happened on the playground at school. It was when I had separation anxiety. As a kid, I had to know where my brother was. If I didn't see him or know where he was, especially on the playground at recess and lunch, I would get upset. I would look at the ground and spin a few times. 

I also tend to fidget. When I’m on my computer, I play with a pencil/pen or bounce a ball up and down on my desk. It's usually when I’m writing, I need to keep my hands busy. Fidgeting could be a sign of nervousness or anxiety. I do have some stims that I do when I’m nervous or anxious. 

My stims happen subconsciously. Sometimes, I can catch myself doing it, but it's something that can’t be helped. You just have to let it go and let stims do whatever they want.
