Interoception: The Hidden Sense That Controls More Than You Think
Can't tell if you're hungry, thirsty, or need the bathroom until it's urgent? Interoception differences are common in autism — and rarely discussed.
Key Takeaways
- Interoception is the sense of your body's internal state — hunger, thirst, pain, temperature, heart rate, and emotions
- For many autistic people, these signals are muted, delayed, or absent until they become urgent
- Poor interoception is directly linked to alexithymia (difficulty naming emotions) and irregular eating patterns
- Interoceptive awareness can be developed through body scans, scheduled meals, and mindfulness practices
The Eighth Sense
You've heard of the five senses. You might know about vestibular (balance) and proprioceptive (body position) senses.
But interoception — the sense of your body's internal state — is the one most people have never heard of.
And it's one of the most affected in autism.
Interoception is how your brain registers hunger, thirst, pain, temperature, heart rate, and the need to use the bathroom.
For many autistic people, these signals are muted, delayed, or completely absent until they become urgent.
The Ripple Effects
Interoception differences have far-reaching consequences.
Difficulty identifying emotions (because emotions are felt through the body) is directly linked to interoception. This experience is called alexithymia, and it's extremely common among autistic individuals.
But that's just the start.
Poor interoception also contributes to irregular eating patterns, dehydration, chronic health issues from not recognizing symptoms, and difficulty with emotional regulation.
Building Interoceptive Awareness
The good news? Interoceptive awareness can be developed.
Regular body scans, scheduled meals and hydration (rather than relying on hunger/thirst cues), and mindfulness practices focused on physical sensation can all help.
