What Is Sensory Processing?
Every moment, our brain receives input from our senses: sight, sound, touch, smell, taste, and two less-known senses — proprioception (body position) and vestibular (balance and movement). Most people process this input automatically without thinking about it.
For many autistic children, this processing system is dysregulated. The brain either over-registers input (hypersensitivity) or under-registers it (hyposensitivity) — or both, in different senses at different times.
This is known as Sensory Processing Disorder (SPD) or Sensory Integration Dysfunction. It is not laziness, stubbornness, or bad behavior. It is neurology.
Why India Makes This Harder
Indian sensory environments are intense. Festivals involve firecrackers, bright lights, loudspeakers, and crowds. Weddings run for hours with recorded music at 100+ decibels. Temple visits include incense, bell sounds, and large crowds. Family gatherings involve being touched by multiple relatives.
For a sensory-sensitive autistic child, these environments are not celebration — they are assault.
Signs of Sensory Hypersensitivity (Over-registration)
Sound:
- Covers ears at everyday sounds (ceiling fans, vehicles, blenders)
- Distressed at crowded, noisy places (malls, markets, weddings)
- Reacts intensely to sounds others barely notice
Touch:
- Removes clothes immediately when dressed
- Refuses tags, seams, certain textures
- Distressed by haircuts, nail cutting, face washing
- Dislikes being hugged or touched unexpectedly
Food:
- Very limited diet, strong reactions to texture, temperature, smell
- Gags at foods others tolerate easily
- Prefers only specific brands or preparations
Sight:
- Upset by bright lights, fluorescent lighting
- Distressed at busy visual environments
Signs of Sensory Hyposensitivity (Under-registration)
- Seeks intense sensory input: spinning, jumping, crashing into things
- Doesn't notice pain that would stop other children
- Mouths objects far past the developmental stage
- Needs very strong flavors or temperatures
- Seeks tight hugs, compression, and deep pressure
Common Indian Situations That Trigger Sensory Dysregulation
| Situation | Sensory Trigger |
|---|---|
| Diwali | Firecrackers, smoke, sudden loud noise |
| Weddings | Recorded music at high volume, crowds, itchy clothes |
| School prayer assembly | Loud speakers, bright open courtyard |
| Temple visits | Incense smell, bell sounds, touching crowds |
| Haircut at barber | Clippers sound, neck touching, cape texture |
| Rickshaw/bus commute | Motion, engine noise, body contact |
| Holi | Water, colors on skin, noise |
Occupational Therapy: The Main Treatment
The primary treatment for sensory processing difficulties is Sensory Integration Therapy (SIT), delivered by an Occupational Therapist (OT) trained in sensory processing.
An OT will assess your child's sensory profile and design a "sensory diet" — a personalized plan of activities that provide the kind of input the child's nervous system needs to stay regulated throughout the day.
Finding an OT in India:
- AIIMS, NIMHANS, and Ali Yavar Jung institutes have OTs
- Private OT sessions cost ₹500–2000/session in metro cities
- Lower in smaller cities; some NGOs provide subsidized OT
Home Sensory Diet Ideas (India-Adapted)
For hypersensitive children:
- Noise-cancelling earphones or earmuffs at loud events
- Seamless underwear and tagless clothing (available online)
- Sensory breaks in a quiet, dim space during parties
- Gradual exposure to triggers — never forced
For hyposensitive children who seek input:
- Jumping on a mattress (5 minutes, 3x/day)
- Carrying heavy grocery bags (proprioceptive input)
- Rolling in a blanket (the "samosa roll")
- Climbing, wrestling, rough-and-tumble play
- Stirring thick dough, kneading clay
Using Autism Saathi for Sensory Tracking
The Autism Saathi app includes a Sensory Profile assessment tool and a library of home sensory diet activities — all adapted for Indian homes, with no special equipment needed.
