Your feelings arrive all at once
Irritated, then suddenly furious, with nothing in between. The early signs were there. They didn't get through.
Interoception: What It Is and How to Build It
You didn't notice you were stressed until the headache arrived.
Interoception is your sense of what's happening inside your body. Most of us were taught to tune it out. Here's why it matters, and how to tune it back in.
Hungry, then suddenly ravenous. Fine, then suddenly furious. Coping, then suddenly in bed for the weekend. If your body's signals only seem to arrive at full volume, this page is for you.
What is interoception?
Interoception is your sense of what's happening inside your body: your heartbeat, breathing, hunger, temperature, tension and gut feelings. It's how your brain keeps track of your internal state, and it shapes your emotions, your stress levels and your decisions. It's sometimes called the eighth sense.
You've probably heard of the five senses that look outward. Interoception looks inward. It's the reason you know you're tired before you yawn, or that something's off before you can say what. Researchers have traced much of it to a part of the brain called the insula, which pulls those body signals together into a felt sense of how you are.
Here's the bit that matters most for change. Psychologists such as Lisa Feldman Barrett argue that emotions are built partly from these body signals. Your brain reads a racing heart and a tight chest, looks at the situation, and makes its best guess: anxious, excited, angry. The clearer the signal, the better the guess.
Signs your interoception could use some attention.
You miss the basic signals
Not noticing you're hungry, thirsty or busting for the loo until it's urgent. Working through lunch without realising.
Stress shows up as symptoms
You don't feel stressed. You get a headache, a sore jaw, a gut that flares. Your body is turning the volume up because nobody answered the quiet version.
Or everything feels too loud
For some people it's the opposite. A faster heartbeat feels like danger, and every flutter becomes something to worry about. That's interoception too, read through a lens of threat.
Why interoception matters for stress and change.
Most high achievers I work with are brilliant at overriding their body. Push through the tiredness. Ignore the knot in the stomach. Get on with it. That works, for a while. It's also how people end up blindsided by burnout they never saw coming, because every early signal was switched off at the source.
Interoception is the early warning system. It's how you notice you're tipping out of your window of tolerance at 30% instead of 90%. It's how you tell the difference between a gut feeling worth trusting and anxiety worth questioning. And it's how identity work becomes something you can feel, not only something you understand.
The good news: it's a skill. It can be built at any age.
How to build your interoception.
Five practices, from quickest to deepest. Pick one and do it daily for two weeks before adding another.
01
Do a three-times-a-day check-in
Morning, mid-afternoon and before bed. Ask: where's my breath, what's my body doing, what's the temperature of this moment? Thirty seconds. You're teaching your brain that these signals are worth noticing.
02
Find your heartbeat
Sit still and see if you can feel your heartbeat without touching your pulse. Chest, throat, hands, wherever it shows up. Don't worry if you can't at first. Most people can't. Trying is the training.
03
Breathe with your attention on your heart
Slow your breathing to about five seconds in and five seconds out, with your attention on the area around your heart. This is the foundation of HeartMath's practice, and with a heart rate variability sensor you can watch your body respond in real time. Few things build interoception faster than seeing it on a screen.
04
Name the sensation before the emotion
When a feeling hits, describe the body part first. "Hot face, tight fists, fast breath" before "I'm angry". This slows the jump from signal to story and gives you a moment to choose.
05
Use ordinary moments
The first sip of a coffee. The water on your back in the shower. The moment your feet hit the floor in the morning. Pick one moment a day and actually feel it. Interoception gets built in everyday life, not only on a cushion.
"Your body has been sending you messages your whole life. Interoception is learning to open them while they're still whispers, not waiting until they're shouting."
A note on numbness, trauma and neurodiversity.
For some people, tuning in to the body doesn't feel neutral. If you've lived through trauma, numbness may have been how you got through, and turning the volume back up can bring up more than you expect. If you notice flashbacks, panic, or feeling detached from your body or your surroundings, please do this work with a trauma-informed psychologist or counsellor.
Interoception also often works differently for autistic and ADHD people. Signals can feel too loud, too quiet or hard to make sense of. That's a difference, not a deficit, and an occupational therapist who specialises in interoception can help you find what works for you.
What I offer is somatic practice and coaching, not therapy. I'm a HeartMath Certified Trainer & Coach, ACT Coach and IMMA Accredited Mindfulness Trainer. If you're in crisis, call Lifeline on 13 11 14, or 000 in an emergency.
Regulation is the floor, not the ceiling.
Feeling what's happening inside you is the start. Once you can feel it, you can steady it. And once you can steady it, you can start looking at the stories that kept setting it off.
That's the path the Self Blueprint follows: body first, then the story, then the new design. The free Stage Assessment takes four minutes and shows you where to start.

Questions people actually ask.
What is interoception? Interoception is your sense of what's happening inside your body: your heartbeat, breathing, hunger, temperature, tension and gut feelings. It's how your brain keeps track of your internal state, and it shapes your emotions, stress levels and decisions.
What's the difference between interoception and proprioception? Proprioception tells you where your body is in space, like knowing where your hand is with your eyes closed. Interoception tells you what's happening inside your body, like noticing your heart racing or that you're hungry.
Can you improve interoception? Yes. Interoceptive awareness responds to practice. Regular body check-ins, slow breathing with attention on your heart, and naming sensations before emotions all build it over weeks and months.
What is interoceptive awareness? Interoceptive awareness is how well you notice and make sense of your internal body signals. Researchers separate it from interoceptive accuracy, which is how precisely you can detect a signal like your own heartbeat. Both can be trained.
Is interoception linked to anxiety? Often, yes. Some people with anxiety are very tuned in to body signals and read them as danger, so a faster heartbeat becomes a sign of panic. Building interoception is partly about noticing signals and partly about learning to read them more calmly.
Is interoception different for autistic or ADHD people? Research suggests interoception often works differently for autistic and ADHD people. Signals might feel too loud, too quiet or hard to read. If that's you, an occupational therapist who specialises in interoception can help.
