Why do we chew ?

This is a constant question we get asked.  Maybe you are a chewer or maybe you have a child that chews? You probably like most wonder why? Perhaps you’ve tried to stop chewing, but it didn’t work? That’s because chewing is a very common stim, and stimming is an essential part of self-regulation.

Chewing is related to our sensory processing system!

It’s quite common for autistic people and people with sensory difficulties to have problems with their sensory system. It’s all to do with our senses and how our brain responds to the messages they send us.

We have 5 senses right?

Wrong! We are commonly taught that we have five senses:

  • Sight
  • Sound
  • Smell
  • Taste
  • Touch

“We actually have 8 senses, the 5 you know from school PLUS, proprioception, interoception & vestibular”


This is understanding what is going on inside of our bodies. Interoception lets us know if we are hungry or thirsty or if we need to go to the toilet. People who are struggling with interception may forget to eat or struggle with potty training. Learn more about Intericpetion here.

Vestibular is our sense of balance and spatial awareness. The vestibular purpose is coordination movement and balance. If you struggle with vestibular, you may have problems riding a bike. Learn more about our vestibular sense here.


That’s our body awareness, knowing which parts of our body do what and where our limbs are in space. The proprioceptive system forms sensory input that sends messages to the muscles and joints in our bodies. That is how we know where our limbs are in relation to objects and people. If you struggle with proprioception, you may struggle with things like catching a ball. Learn more about our proprioception sense here.

Have You Ever Wondered Why We Chew?

So why is this important to chewing?

If someone has difficulties with their proprioceptive system, it can cause problems with movement and levels of arousal. Some people struggle to process some or all of their senses. That’s because the signals go to the brain, but they get jumbled up before the brain forms the appropriate response. This can cause incorrect sensory signals to be sent to the muscles in your oral sensory system and can cause the need to bite or chew.

It can also cause a Sensory overload.

Sensory overload is where one or more of the senses is experiences over stimulation to the environment.

Sensory overload can cause stress, anxiety and fear and lots of other unwanted behaviours such as:

Lack of focus
Covering eyes and ears

Everyone will experience sensory overload differently.

If you can catch it before you go too far, self-regulating and stimming can help.

Stimming is self-stimulatory behaviour which is repetitive movements, moving objects, sounds, and words.

People stim in different ways, but some of the most common stims are:

Hand Flapping
Repeating words or phrases

Stimming is self-regulating are really important. It happens when we need to regulate the proprioceptive system. By regulating the system, it can help us to feel calm, safe and organised.

Chewing is a common stim, so addressing the need to chew is very important.

“Stimming is like breathing just as natural just as important.”

— The Mighty

We can support the need to chew by trying some oral proprioceptive activities like:

Blowing Bubbles
Blowing Whistles
Blowing through straws
Chewing gum
Eating Crunchy foods like carrots
Sucking on boiled sweets
Bouncing on trampolines
Sucking yoghurts and milkshakes through a straw
And Chewigems
Chewing is such a great way to calm and organise the sensory system.

The good thing about Chewigems is that they are portable. Pop them in your bag, around your neck, and take them everywhere!

Chewing is a great way to calm the sensory system, self-regulate and stim!
