Understanding Sensory Needs: A Practical Guide for Support Workers and Families
Sensory processing affects how people experience everyday life. This practical guide explains the eight senses, what over- and under-sensitivity look like in real situations, and how support workers can make a genuine difference.
Understanding Sensory Needs: A Practical Guide for Support Workers and Families
When we talk about the senses, most of us think of five: sight, hearing, taste, smell, and touch. But there are actually eight senses that shape how a person experiences the world. For many people living with a disability, those sensory experiences can be intense, confusing, or overwhelming in ways that are not always obvious to those around them.
Understanding sensory needs is one of the most practical things a support worker or family member can do. It can transform everyday moments (a trip to the shops, a meal, getting dressed in the morning) from a source of stress into something manageable, even enjoyable.
This guide is written for support workers, carers, and families who want to understand sensory needs more deeply and respond in ways that genuinely help.
The Eight Senses
Most people are familiar with the traditional five senses. But three more are just as important, and for many of the people we support, they are just as influential.
The Five You Know
1. Vision processes light, colour, movement, and contrast.
2. Hearing processes sound, pitch, volume, and background noise.
3. Smell (olfactory) detects and interprets scents in the environment.
4. Taste (gustatory) experiences flavour, oral texture, and temperature of food and drink.
5. Touch (tactile) feels pressure, temperature, texture, and pain on the skin.
The Three Less Known
6. Proprioception is our sense of where the body is in space. It guides how much force to use, how to grip a cup, and how to move without falling.
7. Vestibular governs balance, movement, and head position. It keeps us upright, helps us track movement, and allows us to tolerate being spun or tilted.
8. Interoception is our internal body awareness. It is how we feel hunger, thirst, a full bladder, pain, anxiety, or fatigue from the inside.
How Sensory Processing Works
The brain constantly receives signals from all eight senses at once. It filters, organises, and interprets these signals so we can respond appropriately. For most people, this happens automatically and without effort.
For some people (including many with autism, ADHD, cerebral palsy, acquired brain injury, intellectual disability, or sensory processing disorder) this filtering process works differently. The brain may receive too many signals at once, not enough, or it may struggle to organise them in a way that makes sense.
This is not a choice, a behaviour problem, or a lack of effort. It is a neurological difference that deserves to be understood and respected.
Sensory Over-Sensitivity (Hypersensitivity)
Someone who is over-sensitive to a sense experiences it more intensely than most people. What feels like ordinary background noise or a light touch to one person can feel genuinely painful or overwhelming to another.
Signs to look for
Sound Sensitivity
Covering ears in response to sounds others barely notice, such as fans, crowd noise, or the hum of fluorescent lights. Loud environments like shopping centres or busy restaurants can be genuinely overwhelming.

What helps
Modify the environment
Dim lights, turn off background noise, remove clothing tags, and offer soft natural fabrics. Build regular quiet breaks into the routine before the person becomes overwhelmed, not only after. Always give advance notice before touch or movement.
Respect sensory preferences
Honour food textures and temperatures at mealtimes. Introduce new foods gradually, calmly, and without pressure. Treat headphones, sunglasses, and caps as legitimate support tools. Ask team members to avoid personal fragrance in shared spaces and use unscented products.
Sensory Under-Sensitivity (Hyposensitivity)
Someone who is under-sensitive to a sense may appear not to notice things that others find obvious. They may seek out stronger or more intense sensory input because their brain is not registering lower-level signals.
Signs to look for
Seeking pressure
Touching everything, seeking firm contact, pushing against surfaces, or preferring heavy blankets and tight clothing
High pain threshold
Not noticing pain, heat, or cold as others do, including failing to respond to injuries that would be immediately obvious to most people
Movement seeking
Spinning, rocking, jumping, or crashing into things. Needing constant movement in order to stay focused and regulated
Body and internal awareness
Appearing clumsy, bumping into objects frequently, or not noticing hunger, thirst, or a full bladder until the sensation becomes extreme
What helps
Heavy work and proprioception
Carrying heavy items, pushing a trolley, kneading dough, and gardening all provide the deep pressure input the body is seeking. These activities are not treats; they are meeting a genuine neurological need.

Sensory Needs in Everyday Life
It helps to think about specific everyday situations and the sensory challenges they may contain.
Mealtimes
For someone with tactile sensitivity, clothing is a daily sensory challenge. Seams, labels, elastic waistbands, stiff fabrics, or anything wet against the skin can cause real discomfort. Seamless clothing, natural fibres, and consistent comfortable options can make mornings significantly easier. Routine and predictability matter just as much as the clothing itself.
Mealtimes involve multiple senses at once: smell, taste, oral texture, temperature, and the visual presentation of food. Someone with sensory sensitivities may appear to be a fussy eater but is responding to genuine discomfort. Respecting preferences, approaching new textures gradually, and keeping mealtimes calm makes a real difference.
Personal Care
Shopping centres, public transport, markets, and restaurants combine noise, bright lights, crowds, unfamiliar smells, and unpredictable movement all at once. For someone with sensory sensitivities, this can be exhausting. Choosing quieter times of day, using noise-reducing headphones, planning a clear exit route, and identifying a calm space nearby all support a successful outing.
Showering, hair washing, teeth brushing, and nail trimming all involve significant tactile and proprioceptive input. The pressure of water, the feel of a toothbrush, or having nails touched can be experienced as intense or painful. A consistent routine, warm-up time before tasks, preferred products, and an unhurried approach can significantly reduce distress.
Sensory Environments Matter
The spaces where people spend their time have a direct effect on how regulated they feel. Support workers can make a genuine difference by thinking about the environment, not only the person.
At Home
Keep background noise from televisions, radios, and appliances to a minimum. Use soft, warm lighting rather than harsh fluorescent lights. Designate a calm, low-stimulation space the person can access when overwhelmed, and keep the home organised and predictable.
In Shared Living
Be mindful of strong cooking smells, cleaning products, and personal fragrances in shared spaces. Communicate clearly about schedule changes, as unpredictability can be just as overwhelming as sensory overload itself. Respect that each person in a shared home has their own sensory profile.
In the Community
Plan ahead by checking venues for sensory considerations before attending. Build in extra time, as rushing amplifies sensory stress. Always have a quiet exit plan ready, and follow the person's lead about how long to stay and when it is time to go.
Behaviour is Communication
One of the most important things to understand about sensory responses is this: what we sometimes call "challenging behaviour" is most often a sensory response. A person who hits, bites, withdraws, shuts down, screams, or refuses to move is frequently communicating, in the only way currently available to them, that something in their environment is too much, or not enough.
Before asking "Why are they doing that?", ask "What might they be feeling right now, and what might they be trying to tell me?"
When we approach sensory responses with curiosity rather than judgement, we are far more likely to find the right support. And the person is far more likely to feel genuinely understood.
Building a Sensory Profile
Every person's sensory needs are unique. What is calming for one person may be distressing for another. The most useful thing a support team can do is build an individual sensory profile, developed with the person themselves, their family, and any allied health professionals involved in their care.
What to include
Record which senses the person is over-sensitive or under-sensitive to, specific triggers to manage, activities and strategies that support regulation, early signs of becoming overwhelmed, and agreed responses when those signs appear.
How to use it
A sensory profile is a living document. Share it with all team members and review it regularly as the person's needs and preferences evolve. Involve an occupational therapist where possible to ensure the profile is evidence-based and accurately reflects the person's experience.
A Note on Interoception
Interoception often receives less attention than the other senses, but it is worth highlighting separately. Many people with disability experience reduced interoceptive awareness, meaning they may not notice internal signals such as hunger, thirst, pain, a full bladder, anxiety, or fatigue until those signals become extreme.
This has practical implications for daily support. Rather than waiting for a person to report that they are hungry or need the bathroom, regular proactive check-ins build a routine that supports body awareness. It also means emotional regulation can be harder: a person may not notice they are anxious until they are already overwhelmed, because the quieter, earlier signals simply did not register. Understanding interoception helps us support people with greater empathy and foresight.
How Focus ACT Approaches Sensory Needs
At Focus ACT, understanding how each person experiences the world is the foundation of the support we provide. Our support workers take time to learn each person's individual sensory profile, observing carefully, listening to families and allied health professionals, and building consistent routines that reduce unpredictability and support regulation. We adjust environments where we can, advocate for changes where we cannot, and we always approach distress with curiosity rather than assumption. We work alongside occupational therapists and other specialists to ensure our approach is evidence-based and truly person-centred, because when sensory needs are understood and respected, everyday life becomes not just more comfortable, but genuinely richer.
