Sensory processing challenges: when the world feels too much (or not enough)

What is sensory processing?

Sensory processing refers to how the brain receives, organizes, and responds to information from the senses — sight, sound, touch, taste, smell, movement, and body awareness. Most people process sensory information automatically and without much difficulty. For some children, this process works differently, leading to responses that seem unusually intense, unusually muted, or inconsistent. This is sometimes called sensory processing disorder or sensory processing differences, though these terms are used in different ways by different professionals.

Over-sensitivity (hypersensitivity)

Children who are over-sensitive to sensory input may be distressed by sounds that others find tolerable, refuse to wear certain clothing because of how it feels, be very picky about food textures, avoid messy play, be bothered by bright lights, or become overwhelmed in busy environments. These reactions are genuine — the child is not being dramatic or difficult. Their nervous system is processing sensory input more intensely than typical.

Sensory seeking (hyposensitivity)

Some children seem to need more sensory input than others. They may crash into furniture, seek out tight hugs, chew on objects, make loud noises, or be constantly in motion. This sensory-seeking behavior is the nervous system's way of getting the input it needs to feel regulated. It can look like hyperactivity or impulsivity, but the underlying cause is different.

How sensory differences affect daily life

Sensory processing differences can affect many areas of daily life — getting dressed, eating, participating in school, playing with other children, and managing transitions. Children may have meltdowns in response to sensory triggers that adults don't notice. Understanding that a child's behavior is driven by sensory processing differences — rather than defiance or manipulation — can change how families and educators respond.

How occupational therapy can help

Occupational therapists (OTs) who specialize in sensory processing work with children to help their nervous systems become better regulated. This may involve sensory integration therapy, which uses structured sensory activities to help the brain process input more effectively. OTs also work with families to create sensory-friendly environments and routines at home and school. Progress takes time, but many children show meaningful improvement with consistent support.
