Many people have not come across the idea of interoception before. So what is it? Interoception is known as the eighth sense. It is the ability to feel sensations in the body. It includes things like the sensation of temperature, hunger and thirst or needing the toilet. One thing to know about interoception is that it is common for autistic people to have low interoceptive awareness.
When I was a child I had big troubles with sensing heat and cold and would wear inappropriate clothing for the weather. It took me a lot longer to toilet train than most kids. In fact it is common for autistic children to toilet train later than their neurotypical peers and when they do they can still struggle with the sensations involved in toileting. This is likely to be related to interoceptive awareness.
Another thing to know about interception is that there is an emotional element to it. The condition alexithymia – sometimes called ‘emotion blindness’ – is where a person cannot articulate or be aware of their emotions. This is common amongst autistic folks as well. I definitely hav alexithymia. It doesn’t mean I lack emotions – far from it! What it means is that an emotion needs to be pretty big for me to be aware it is happening and by the time I do it has become quite extreme.
Having low interoceptive awareness can mean different things for different people. It can impact on behaviour. If you imagine that you are really hot and thirsty and depressed and stressed and someone says or does something to upset you how much bigger your reaction would be than if you were physically comfortable and in a good mood. People with strong interoceptive awareness in this situation may take steps to address the issues and avoid difficult situations but if you are not aware of how you are feeling then this is considerably more challenging.
I think everyone needs to know about interoception and particularly the autistic experiences around it. If you want to know more I would highly recommend reading work by my friend, advocate colleague and co-author Dr Emma Goodall who has considerable expertise in this space.
