What are sensory processing difficulties?
Sensory processing difficulties occur when the brain does not process information from sensory stimuli in an expected way.
Individuals who struggle with sensory processing difficulties either over or under respond to sensory stimuli. This is called being hypo-sensitive (under responsive) or hyper-sensitive (over responsive). Hyper-sensitivity creates a quick response and an individual will appear to over-react to very little sensory input. One easily understood example of this would be someone being very sensitive to noise. Hypo-sensitivity in individuals requires extra sensory stimuli and a craving for additional input. Basic examples being spicy or salty foods, and the desire to perpetually rock and spin.
The three categories of sensory processing differences:
1. Sensory modulation disorder.
This affects an individual’s ability to regulate their response to sensory stimuli
2. Sensory based motor disorder.
This affects coordination and balance.
3. Sensory discrimination.
This is the understanding of where the sensory information is coming from.
Under current guidelines in the UK, Sensory Processing Disorder is diagnosed as part of thorough clinical assessments due to the challenges it creates on the functioning of daily life. It is seen as a subtype and not a standalone diagnosis. Sensory processing difficulties are milder in their day-day limitations and can be diagnosed by an Occupational Therapist (OT).
Some experiences change the way we sense the world entirely.
Trauma leaves its mark in many places. In memory, in the body, in the way a room can feel unsafe without explanation. For those living with Post-Traumatic Stress Disorder, or carrying the quiet weight of a traumatic or acquired brain injury, the home is not simply a backdrop to daily life — it is a sensory environment that can either soothe or overwhelm, support or exhaust.
This is something that does not yet receive the acknowledgement it deserves.
The NHS tells us that one in three people who experience trauma may go on to develop PTSD. That one in ten of us will encounter it in our lifetime. And for those living with a traumatic brain injury, research shows that eight in ten have experienced sensory overload since their injury — with a profound effect on their quality of life, their relationships, and their sense of home.
These are not statistics. These are people. Families. Someone's partner, parent, child.
If the way a room is lit, the textures it holds, the sounds it absorbs or amplifies — if any of these things can ease even a little of that daily weight, then it is worth every moment of careful thought. A home that works gently with a changed nervous system is not a luxury.
For many, it is the difference between coping and flourishing.
This is why this work matters. It is why your home deserves to be designed for the way you live and need.
