Sensory sensitivities in autistic children

Why ordinary environments can feel extreme
Many autistic children process sensory input differently — some senses may be amplified (hypersensitive), others may register less than expected (hyposensitive), and this can vary by sense and by day. A supermarket's fluorescent lights, overlapping conversations, and food smells that barely register for one person can be genuinely overwhelming for an autistic child, even painful.
This isn't an overreaction or a behaviour choice — it's the brain processing sensory information in a different way.
Sensory seeking and sensory avoiding
- Seeking behaviours increase input: spinning, jumping, seeking deep pressure, touching textures, humming.
- Avoiding behaviours reduce input: covering ears, avoiding certain fabrics or food textures, refusing certain environments.
A child can be a seeker in one sense (loving movement) and an avoider in another (hating loud noise) at the same time.
Common sensory triggers
- Unexpected or sustained loud noise (hand dryers, fire alarms, crowded rooms)
- Bright or flickering lights
- Clothing tags, seams, or certain fabrics
- Strong smells (perfume, cleaning products, some foods)
- Crowded, visually busy spaces
What helps
- Noise-cancelling or noise-reducing headphones for predictably loud environments
- Advance warning about sensory-heavy events (fire drills, assemblies, parties) where possible
- Sensory breaks — a quiet space to retreat to, even briefly
- Clothing without tags/seams, or letting your child choose textures they're comfortable in
- Following sensory-seeking needs rather than suppressing them — movement breaks, fidget tools, or weighted items can genuinely help regulation rather than being "indulgent"
Sensory overload and meltdowns
A meltdown is often the result of accumulated sensory and/or emotional load exceeding what a child can process — it is not the same as a tantrum, and is rarely something a child can simply "choose" to stop. The most effective response is usually to reduce input (quiet, dim, fewer demands) rather than reasoning or instructing in the moment.
When to talk to your clinician
If sensory sensitivities are significantly limiting daily activities (eating, dressing, school attendance, sleep), an occupational therapist with sensory integration experience can offer a structured assessment and tailored strategies.
