Recognising the signs of hyposensitivity in autism is key to understanding why many autistic people display strong sensory seeking patterns. Unlike hypersensitivity, where sensory input feels overwhelming, hyposensitivity means that the brain under-registers sensations. This often leads to behaviours designed to increase stimulation and maintain balance.

These symptoms may not always be obvious at first, but they can affect how a person interacts with their surroundings. By noticing these early, parents, caregivers, and professionals can create strategies to support comfort, safety, and wellbeing.

Common Indicators to Look For

Here are some everyday indicators that highlight the signs of hyposensitivity in autism:

Seeking deep pressure

A child may enjoy tight hugs, crash into furniture, or wrap themselves tightly in blankets. Occupational therapy can provide safe activities that meet this need.

Unbothered by loud sounds or bright lights

Unlike hypersensitivity, hyposensitive individuals may not react to sirens or bright environments. Safety-focused interventions such as structured teaching and occupational therapy are more appropriate for building awareness and ensuring safety.

Chewing or mouthing non-food items

Chewing on pencils, clothing, or toys can be soothing. Therapists often introduce chew-safe tools to provide alternatives.

Constant movement and fidgeting

Repetitive behaviours such as spinning or jumping help stimulate under-responsive systems. Structured physical activities support healthy sensory regulation.
