People with Autism Level 3 are often extremely sensitive to sound, especially in busy or unpredictable places. Even “normal” noise can feel painful, frightening, or overwhelming.

5  

• TV, radio, music
   
• Vacuum cleaner, washing machine
   
• Traffic, buses, trains
   
• People talking all at once
   

• Supermarkets
   
• Schools
   
• Shopping centres
   
• Hospitals
   
• Events & gatherings
   

• Doors slamming
   
• Alarms
   
• Sirens
   
• Shouting
   
• Dropping objects
   

These sounds are unpredictable, which makes them even more stressful.

When overwhelmed by noise or crowds, a person may:

• Cover ears
   
• Cry or scream
   
• Run away
   
• Freeze or shut down
   
• Hit, bite, or throw (out of distress)
   
• Stop communicating
   

⚠️ This is not bad behaviour.
It means: “I’m scared and overloaded.”

✔️ Noise-cancelling headphones
✔️ Ear defenders
✔️ Quiet background music
✔️ Turn TV/radio down

✔️ Quiet room at home
✔️ Calm corner with cushions
✔️ Dim lights + soft sounds
✔️ Door closed when needed

✔️ Explain where you’re going
✔️ Show pictures first
✔️ Use “Now / Next” cards
✔️ Practice short visits

✔️ Go at quiet times
✔️ Short trips only
✔️ Take regular breaks
✔️ Leave early if needed

If distress begins:

🛑 Step 1: Reduce sound
→ Headphones / quiet space

🫂 Step 2: Provide comfort
→ Weighted blanket / hug (if accepted)

🎵 Step 3: Use one “safe” sound
→ Favourite calm song on repeat

🕯️ Step 4: Lower stimulation
→ Lights down, voices soft

For Autism Level 3:

Loud noise + crowds + sudden sounds
= Fear + confusion + overload
 

With the right support, this becomes:

Safety + calm + confidence 🌱

People with Autism Level 3 often experience very strong sensitivity to light, movement, and busy visual environments.

Bright lights, fast movement, or cluttered spaces can feel overwhelming, confusing, and distressing, making it hard to stay calm and focused.

Creating a visually calm environment is essential for comfort and wellbeing.

In Autism Level 3, the brain may:

• Struggle to filter visual information
   
• Notice every detail at once
   
• Become overloaded quickly
   
• Find it hard to focus on one thing
   

Too much visual input can cause stress and shutdown.

Overload is not behaviour — it is a physical response.

Bright or harsh lighting may cause:

• Headaches or eye strain
   
• Agitation or anxiety
   
• Covering eyes
   
• Avoidance of rooms
   
• Increased meltdowns
   

Common triggers include:

• Fluorescent lights
   
• Flickering bulbs
   
• Strong sunlight
   
• Reflections
   
• Screens
   

Fast or unexpected movement can feel frightening.

This may include:

• People walking past quickly
   
• Crowded spaces
   
• Escalators
   
• Busy classrooms
   
• Traffic
   
• TV screens with fast scenes
   

Movement overload can increase anxiety.

Busy environments can be very difficult.

Clutter may include:

• Too many posters
   
• Messy rooms
   
• Crowded shelves
   
• Lots of colours
   
• Busy patterns
   

Too much visual information makes it hard to relax.

Visual overload may show as:

• Covering eyes
   
• Turning away
   
• Crying or shouting
   
• Pacing or rocking
   
• Hiding
   
• Refusing to enter rooms
   
• Shutdown
   

These are signs of distress.

Helpful strategies include:

People with Autism Level 3 often experience very strong sensitivity to touch, textures, and changes in temperature.

Sensations that feel normal to others may feel painful, uncomfortable, or overwhelming, causing distress and difficulty with daily activities.

Respecting these sensitivities is essential for comfort and emotional safety.

In Autism Level 3, the brain may:

• Process touch and temperature more intensely
   
• Struggle to filter physical sensations
   
• React quickly to discomfort
   
• Become overloaded easily
   

These responses are physical, not behavioural.

Touch sensitivities may include:

• Discomfort with hugs or physical contact
   
• Distress from unexpected touch
   
• Sensitivity to brushing hair or teeth
   
• Dislike of hand-holding
   
• Avoidance of crowded spaces
   

Even gentle touch can feel overwhelming.

Certain textures may cause strong discomfort, including:

• Clothing labels or seams
   
• Rough or stiff fabrics
   
• Wet or sticky surfaces
   
• Certain food textures
   
• Bedding materials
   

Texture discomfort can affect dressing and eating.

Sudden or extreme temperature changes may cause:

• Distress when entering hot or cold rooms
   
• Difficulty regulating body temperature
   
• Sensitivity to drafts or heaters
   
• Discomfort with sweating or cold skin
   

Temperature changes can feel intense.

Distress may show as:

• Pulling away from touch
   
• Removing clothing
   
• Crying or shouting
   
• Agitation or withdrawal
   
• Refusal of activities
   
• Meltdowns
   

These are signs of overload.

Helpful strategies include:

• Ask before touching
   
• Warn before personal care
   
• Respect boundaries
   
• Use firm, predictable touch if preferred
   

• Choose soft, seamless clothing
   
• Remove labels
   
• Let the person choose fabrics
   
• Use familiar bedding
   

• Dress in layers
   
• Keep rooms at steady temperatures
   
• Use blankets or cooling aids
   
• Avoid sudden changes
   

Support must be individual.

For people with Autism Level 3, sensitivity to touch, textures, and temperature can be intense and distressing.
Respecting these needs helps reduce anxiety, build trust, and improve quality of life.

Comfort comes first.

People with Autism Level 3 often experience very strong sensitivity to smells and tastes.
Scents or flavours that seem mild to others can feel overpowering, unpleasant, or distressing.

These sensitivities can strongly affect eating, daily routines, and comfort.

In Autism Level 3, the brain may:

• Process smell and taste more intensely
   
• Struggle to filter sensory input
   
• React quickly to unpleasant sensations
   
• Become overloaded easily
   

These reactions are physical, not behavioural.

Strong smells may cause distress, including:

• Perfume or aftershave
   
• Cleaning products
   
• Air fresheners
   
• Cooking odours
   
• Smoke or traffic fumes
   

Reactions may include covering the nose, gagging, or leaving the area.

Taste sensitivities may include:

• Strong dislike of bitter, sour, or spicy foods
   
• Preference for bland or familiar foods
   
• Rejection of mixed textures
   
• Sensitivity to temperature of food
   
• Gagging or vomiting with certain foods
   

Food can feel unsafe.

Distress may show as:

• Refusing food
   
• Nausea or gagging
   
• Crying or shouting
   
• Pushing food away
   
• Leaving rooms with strong smells
   
• Meltdowns
   

These are signs of overload.

Helpful strategies include:

• Use unscented products
   
• Avoid strong perfumes
   
• Ventilate rooms well
   
• Cook when possible away from living areas
   
• Respect avoidance
   

• Offer familiar “safe foods”
   
• Introduce new foods slowly
   
• Keep textures separate
   
• Avoid pressure to eat
   
• Use consistent routines
   

Support must be personalised.

For people with Autism Level 3, strong reactions to smells and tastes are real and distressing.
Respecting these sensitivities helps improve comfort, nutrition, and emotional wellbeing.

Food and environment should feel safe.

When sensory, emotional, or mental demands become too much, autistic people may experience overload.
This is the body and brain’s way of saying “I can’t cope right now.”

Overload is not bad behaviour — it is distress.

Signs may include:

• Increased stimming (rocking, flapping, repeating sounds)
   
• Agitation or irritability
   
• Pacing or restlessness
   
• Covering ears or eyes
   
• Crying or shouting
   
• Trying to escape the situation
   
• Withdrawing or becoming very quiet (shutdown)
   
• Refusing interaction
   

Each person shows overload differently.

Overload can be triggered by:

• Too much noise, light, or movement
   
• Busy or crowded environments
   
• Sudden changes
   
• Social pressure
   
• Fatigue
   
• Emotional stress
   
• Too many demands
   

When the brain is overwhelmed, coping skills disappear.

When signs appear, act early:

• Lower noise and lighting
   
• Move to a quiet space
   
• Remove extra people
   
• Turn off screens if needed
   

• Stop non-essential tasks
   
• Pause instructions
   
• Avoid questions
   
• Reduce expectations
   

• Go back to familiar activities
   
• Use comfort items
   
• Follow known routines
   
• Use calming music or silence
   
• Allow rest
   

Safety comes first.

Responding calmly helps:

• Prevent meltdowns
   
• Reduce recovery time
   
• Build trust
   
• Improve emotional regulation
   
• Protect wellbeing
   

Your calm becomes their calm.

Overload signs are signals of distress, not misbehaviour.
When they appear, reduce input, lower demands, and return to a safe routine.

Early support prevents crisis.
