Vestibular Hypersensitivity – A Fear of Movement
As a parent, when you see your child refusing to play on swings, afraid to climb stairs, or even feeling anxious during transitions at school, you might think: "Why are other children playing so happily, while mine seems so fearful?" A teacher might also tell you: "They always stand to the side and don't join in!" or "They don't respond when called—I'm not sure if they're even listening."
Try not to blame yourself or your child. Let's explore this together—there may be an important reason behind their behaviour: vestibular hypersensitivity.

What is the Vestibular Sense?
The vestibular system is our body's built-in "balance sensor," located in the inner ear. It helps us perceive whether we are moving, tilting, or spinning. In simple terms, it tells us: "Am I standing steady?" and "Am I about to fall?"
For children with vestibular hypersensitivity, this sensor is overly sensitive. Their bodies often misinterpret their environment as having a "risk of falling," so they are in a constant state of high alert.
A child with vestibular hypersensitivity might:
· Be afraid of heights—even too scared to go down a low slide
· Fear swinging—crying even with the gentlest motion
· Be terrified of lifts—finding the feeling of going up and down frightening
· Be scared of stairs—especially when looking down
· Be fearful of being bumped into—feeling anxious in queues, during class transitions, or in crowded places
· Be afraid of slopes—holding on tightly when walking on an incline

Case Example: The Story of Four-Year-Old Lok Lok
Four-year-old Lok Lok had been in kindergarten for over six months, but his teacher had never heard him speak. During outdoor playtime, while other children ran to the slide and swings, Lok Lok would always stand to the side, quietly watching his classmates.
His teacher initially thought he was just shy and encouraged him to join in. But she gradually noticed that Lok Lok also seemed unresponsive to simple classroom instructions, like "take out your book" or "line up to wash your hands."
His teacher became concerned: "Could Lok Lok have a cognitive delay?" She arranged to meet with his parents.
His mother was equally confused: "He's not like this at home! He talks and plays with us. Why does he become a completely different person at school?"
It was only after an assessment by an occupational therapist that they discovered Lok Lok had significant vestibular hypersensitivity.
Lok Lok wasn't refusing to participate. When he saw other children running and jumping, his body was already sending him alarm signals: "This is dangerous! You might fall!" Living in a constant state of high alert, his brain simply had no capacity left to process his teacher's words, let alone respond verbally.
His "silence," "standing to the side," and "seeming not to understand" were actually his body's self-protective mechanisms.

Why Does Vestibular Hypersensitivity Cause Emotional Problems?
Imagine if, every day at work, the office floor felt like it was swaying beneath you. You'd have to be careful with every step, afraid of falling. Even the slightest movement from a passing colleague might feel like a potential collision. Would you have the focus to do your job? Would you have the energy to chat with others?
Children with vestibular hypersensitivity live in exactly that kind of world. Their bodies are in a constant "state of alert," draining immense energy just to maintain balance. As a result:
· No energy left to listen → They seem not to understand instructions
· No energy left for socialising → They appear shy or withdrawn
· Constant tension and anxiety → They become easily overwhelmed and have meltdowns
Children with vestibular hypersensitivity live in a world that feels full of "dangers." Their emotional struggles often stem from a fear of losing control over their own bodies.

What Parents Can Observe
If you suspect your child might have vestibular hypersensitivity, watch for these signs:
· Movement play: Do they strongly resist swings, slides, or merry-go-rounds?
· Daily environments: Are they particularly fearful of lifts, stairs, or slopes?
· Crowded places: Do they become especially anxious in queues, during class transitions, or at the mall?
· Body posture: Do they always hold on tightly when sitting on a chair?
· Emotional reactions: Do they become unusually irritable, tearful, or have meltdowns in certain environments?

A Heartfelt Message for Parents
Every parent wants their child to be happy at school and play with others. But when you see your child fearful, withdrawn, or even "misbehaving" because of anxiety, please remember:
They are not being "picky," "shy," or "naughty."
They are simply telling you with their body: "My sensory world is overwhelming!"
Vestibular hypersensitivity is not an illness—it's a sensory processing trait. Once we understand the reasons behind it, we can find more appropriate ways to support our children.
If you're unsure how to help, or if your child's anxiety is significantly affecting their daily life (such as at school, in social situations, or emotionally), it's advisable to seek an assessment from a qualified occupational therapist. An occupational therapist can help identify your child's sensory needs and work with you every step of the way.
Every behaviour is a form of communication. When children can't find the words, we need to learn to read the signs.
