01
Sensory processing differences
The same environment does not feel the same to every nervous system.
Sensory processing describes how the brain and body register, organise and respond to information from the environment and inside the body. Autistic people commonly report sensory differences, and sensory differences are also described by many people with ADHD.
01Hypersensitivity
Input may feel unusually intense, painful, intrusive or impossible to filter. A sound others barely notice may occupy your whole attention.
02Hyposensitivity
Some input may register faintly or late. You might miss hunger, pain, temperature or environmental cues until they become urgent.
03Sensory seeking
Movement, pressure, sound, texture, taste or repetition may help organise attention, increase alertness or create a sense of regulation.
04Mixed and changing patterns
You can seek one kind of input and avoid another, or need different things depending on sleep, hormones, illness, stress and accumulated load.
A sensory profile is descriptive, not diagnostic. People can have meaningful sensory needs for many reasons.
02
Why needs fluctuate
Your threshold is not a fixed character trait.
Sensory tolerance can narrow when the nervous system is already carrying fatigue, illness, pain, hormones, uncertainty, social demands, hunger, poor sleep or burnout.
If the same sound suddenly feels unbearable, the sound may not have changed. The capacity available to process it may have.
03
Overload, shutdown & meltdown
Overload is a capacity event, not a behaviour problem.
When input exceeds what can be processed, thinking, speech, movement and emotional regulation may become harder. One person may become visibly distressed, need to escape or lose control of expression. Another may go quiet, still, distant or unable to respond.
Meltdown
An involuntary outward response to overwhelm. It may involve crying, movement, shouting, panic or an urgent need to escape. It is not a chosen attempt to manipulate.
Shutdown
An involuntary inward response. Speech, movement, decisions or connection may reduce as the system protects itself from further input.

04
Interoception
The body may whisper, arrive late or speak all at once.
Interoception involves sensing internal body states such as hunger, thirst, temperature, pain, fatigue, heartbeat and the need for the toilet. These signals may be difficult to notice, interpret or act on until they become intense.
Regular, low-pressure check-ins can be more useful than waiting to feel a clear signal. Try asking what the body might need rather than whether you can prove the need is strong enough.
A body check-in
Temperature · pressure · hunger · thirst · pain · movement · rest
You do not need to accurately name every sensation. Noticing that something has shifted can be enough to try food, water, movement, the toilet, a layer of clothing or quieter input.

My Sensory Profile
Notice what you avoid, seek and find regulating.
Explore each sensory area without trying to create a permanent label. The useful question is what your nervous system needs in a particular context.
Notice your pattern
Which sounds hurt, compete or disappear?
You might notice: Voices, appliances, traffic, chewing, alarms, overlapping conversation.
Possible supports: Earplugs, headphones, quiet rooms, advance warning, one voice at a time.
Sensory Safety Plan
Decide what helps before language and decisions become harder.
My plan
- Speech becomes harder
- Leave or move somewhere quieter
- I need a quieter space
- Low light and no questions
06
Responding to overload
Make the environment simpler before asking for more regulation.
During overload, language and problem-solving may add more input. Support can be quiet, practical and familiar.
Do not force touch, eye contact, speech or a regulating strategy. Offer simple choices and respect a request for space when it is safe to do so.
07
Sensory safety in daily life
Support works best before the threshold is crossed.
“I focus better away from the main walkway. Could we use the quieter desk?”
“Please let me know before touching me and explain one step at a time.”
“I’d love to come. I may leave early if the noise becomes too much.”
“I need twenty minutes with low light and no questions before we talk.”
Sunglasses, ear protection, movement, familiar food, reduced fragrance, predictable plans and recovery time are not signs of failing to cope. They are ways of making participation more accessible.
08
Professional support
Individual assessment matters more than a fashionable solution.
An occupational therapist with relevant neuroaffirming experience may help clarify sensory patterns, participation barriers and practical environmental supports. A GP can assess new or changing physical symptoms, hearing, pain, migraine, medication effects or other medical contributors.
Be cautious with universal claims
A strategy being popular does not mean it is right for every nervous system.
Evidence for specific sensory-based interventions varies. Supports should be collaborative, individually tailored, physically safe and stopped if they increase distress.
