Sensory Difficulties
Sensory difficulties are common for autistic people and can affect how someone experiences everyday environments. Sounds, lights, textures, smells, tastes, movement or touch may feel overwhelming, uncomfortable, muted or difficult to process.
What are sensory difficulties?
Sensory difficulties happen when the brain processes sensory information differently. For autistic people, sensory input may be experienced more intensely, less intensely, or in a way that feels confusing or difficult to organise. This can affect comfort, emotional regulation, communication, behaviour and day-to-day wellbeing.
How sensory differences can feel
Some autistic people may experience heightened reactions to sensory input, while others may have reduced responses and seek stronger sensory experiences. Many people experience a mixture of both depending on the environment, their stress levels, tiredness, health and what else is happening around them.
Sensory differences are not someone “being difficult”. They are real experiences that can have a significant impact on how safe, comfortable and regulated a person feels.
Common sensory areas
- Sound: loud noises, alarms, crowds, echoing rooms or background noise.
- Light: bright sunlight, fluorescent lighting, flickering screens or busy visual environments.
- Touch: clothing labels, certain fabrics, unexpected touch, hair brushing or tooth brushing.
- Taste and smell: strong smells, food textures, certain flavours or mixed smells in public places.
- Movement and body awareness: needing to move, rock, spin, pressure-seek or avoid certain movements.
Hypersensitivity
Hypersensitivity means being over-sensitive to sensory input. Everyday experiences may feel much stronger, more painful or more overwhelming than other people expect.
- Loud or high-pitched sounds may feel distressing.
- Bright or flickering lights may cause discomfort or pain.
- Certain clothing textures or physical touch may feel unbearable.
- Strong smells or tastes may cause nausea, anxiety or avoidance.
Hyposensitivity
Hyposensitivity means being under-sensitive to sensory input. A person may need stronger or more frequent sensory experiences to feel regulated or aware of their body.
- Seeking loud sounds, bright lights, movement or pressure.
- Enjoying deep pressure, weighted items or firm hugs.
- Reduced awareness of pain, temperature or body signals.
- Needing to move, fidget, chew, spin or touch objects to stay regulated.
Sensory integration difficulties
Sensory difficulties are not always linked to just one sense. Some people may find it hard to process several sensory inputs at once. For example, listening to someone speak in a noisy room, coping with bright lights while navigating a crowded space, or managing smells, sounds and movement at the same time can be exhausting.
This can make busy environments feel overwhelming and may affect concentration, communication, confidence and participation.
How sensory difficulties can impact daily life
- Social settings: parties, shops, classrooms or busy places may lead to overload, anxiety or withdrawal.
- Self-care: brushing teeth, washing hair, getting dressed or eating certain foods may feel uncomfortable or distressing.
- Behaviour and regulation: sensory overload can lead to shutdowns, meltdowns, avoidance or repetitive behaviours used for self-soothing.
- Energy levels: coping with sensory input can be tiring and may affect mood, attention and resilience.
Managing sensory difficulties
- Create sensory-friendly environments: reduce noise, dim lights and provide quiet spaces where possible.
- Use sensory tools: noise-cancelling headphones, sunglasses, fidget toys, chew tools or weighted items may help some people.
- Build predictability: visual schedules and routines can reduce anxiety and make transitions easier.
- Support communication: visual aids, communication cards or agreed signals can help someone express sensory needs.
- Seek professional guidance: occupational therapists and other professionals may offer tailored sensory strategies.
Understanding sensory needs can make a big difference
Sensory difficulties can affect many areas of life, but the right understanding, adjustments and support can help autistic people feel safer, calmer and more able to take part in the things that matter to them.
