What is temperature hypersensitivity?IN BRIEF
Hypersensitivity to thermoception refers to heightened sensitivity to temperature, whether to heat or cold. A person affected may sweat excessively, experience pain, or feel intense chills. While this phenomenon is more common among autistic people, it can also affect individuals without any specific diagnosis.

Definition of thermoceptive hypersensitivity
Thermoceptive hypersensitivity is characterized by an excessive reaction to temperature variations. Certain sensations of heat or cold can be perceived extremely intensely, making everyday situations particularly challenging to manage. It’s not a matter of willpower or maturity. The discomfort felt is very real and can cause genuine suffering.
For some autistic people, it can be difficult to understand what’s happening when the signal for heat or cold is perceived. This can result in reactions that may seem disproportionate to others.
Symptoms of temperature hypersensitivity
When reactions or sensations to temperature variations seem unusual or excessive, this may indicate thermoceptive hypersensitivity. Several symptoms can support this conclusion :
- Burning sensations
- Excessive sweating
- Intense chills
- Persistent pain
Consequences of hypersensitivity to heat and/or cold
It’s often frowned upon, especially for an adult, to have difficulty managing temperature variations. This misunderstanding can lead to feelings of invalidation or judgment, which may have significant negative consequences:
- Difficulty performing certain daily tasks
- Avoidance of situations involving temperature variations
- Reactions perceived as surprising
- Excessive caution
- Fear
- Anxiety
- Depression

Important
It's essential to remember that the person is neither lying nor immature in their response to temperature sensations.
Scenario
Justin feels intense pain in his hands when touching cold food. As a result, he avoids cooking meals he enjoys, simply to avoid handling these foods (e.g., cutting meat).
What are the solutions and strategies for thermoceptive hypersensitivity?
- Avoid excessive temperature variations
- Maintain a stable ambient temperature as much as possible
- Wear appropriate clothing for the conditions
- Muscle strengthening can help alleviate temperature-related pain
- Check for underlying medical causes

Autistic people are thought to have differences in their central nervous system, and this might make them more sensitive to various stimuli, including temperature.
Like many autistic people, my 6-year-old daughter has a lot of trouble falling asleep. For the past three nights or so, she's been complaining of feeling very hot. I proposed several solutions: lighter pyjamas, sleeping naked (impossible for her to consider), a washcloth with cold water. All to no avail. Finally, on the third night, I suggested putting her pyjamas in the freezer. Problem solved! A real miracle! I was so pleased that I immediately texted this solution to my best friend whose son is also hypersensitive. My oldest, 8, who also has autism, couldn't stop laughing and asking me if I'd REALLY put the pyjamas in the freezer. The evening ended with everyone in good spirits. Just goes to show that a situation that may seem exasperating (we sometimes run out of solutions) can turn into a wonderful memory.
