How Does Hyposensitivity Affect Responses to Temperature in Autism? 

Hyposensitivity and temperature response in autism are closely linked, often shaping how children and adults react to everyday environments. For some autistic individuals, the brain under-registers heat or cold, leading to unusual sensory reactions. Instead of pulling away from a hot object or shivering in the cold, they may show little or no outward response. 

This reduced hot/cold sensitivity does not mean they cannot feel temperature at all, but rather that the signals are muted. As a result, they may not recognise discomfort or danger quickly, which can create safety concerns if burns or frostbite go unnoticed. 

Common Sensory Reactions to Temperature 

Here is how hyposensitivity and temperature response in autism may appear in daily life: 

Limited reaction to heat or cold  

A child might play outside without a coat in winter or touch hot objects without complaint. Occupational therapy often focuses on building body awareness and teaching protective routines. 

Seeking extreme temperatures  

Some individuals deliberately press against cold surfaces or seek hot baths, as strong input helps their nervous system register sensations. Structured sensory activities can meet these needs safely. 

Delayed pain or discomfort response  

Instead of reacting immediately, discomfort may only appear later. Parents and carers are encouraged to use regular checks and environmental supports to prevent harm. 

Recognising differences in hot/cold sensitivity helps families create safe, supportive environments. Visit providers like Autism Detect for tailored advice on managing sensory reactions.
