Interoceptive Intelligence: Knowing What's on the Inside

Without bringing your hands to your heart nor elevating your heart rate – can you pause and feel your heartbeat right now?

– How do you feel your heart beating?

– How good are you at noticing or feeling your heartbeat?

– How often do you feel your heartbeat?

The sense nobody told you about

In school we learn about five senses: sight, hearing, taste, smell, and touch. But there's another one working quietly underneath all of them. Interoception is your ability to perceive the internal signals of your own body — your heartbeat, your breath, hunger, fatigue, tension, even the physical texture of an emotion like anxiety.

Here's the exciting part: it's a sense you can train and get better at. And the implications for health and overall wellbeing are tremendous.

Interoceptive intelligence isn't just detecting your heart rate. It's noticing the full range of signals from your body and emotions — which ultimately helps us make stronger connections with ourselves and with others.

What's happening in the brain

Your brain continuously tracks these internal signals, a process vital for maintaining homeostasis — your body's internal balance. These signals travel through the thalamus, which acts as a relay station, passing information along to regions like the insula.

The insula is a deep part of the brain that helps process emotions, taste, and bodily sensations, allowing us to interpret them — like realizing your heart is racing because you're nervous about a presentation, or lit up with excitement at a game.

Researchers measure interoception in a few different ways. One is interoceptive accuracy — how well you actually detect internal signals like your heartbeat. Another is interoceptive attention — how often you notice these signals at all. And these individual differences shape more of life than you'd expect, influencing eating habits, pain perception, and emotional regulation.

It's not simply that more awareness is better. Highly anxious individuals, for instance, may over-focus on internal sensations in a way that amplifies distress, while others may be largely disconnected from their bodily cues. The goal is a strong connection to your internal signals and a balanced, non-reactive relationship with them. (Sounds a lot like yoga, doesn't it?)

Interoception even shapes decision-making. Research suggests people with higher interoceptive awareness may make better choices by subconsciously linking physical sensations to past experience — which might be exactly what's happening when someone "trusts their gut."

Where movement comes in

This is the part I find most exciting, because it's where the science meets what I actually teach.

Practices like yoga, breathwork, and mindful strength training are, in a very real sense, interoception training. When a yoga teacher cues you to feel your ribs expand on an inhale, or to notice the subtle shift in pressure as the breath leaves your body — that's interoceptive attention in action. You're strengthening the very skill the research describes.

And movement trains the balance the research points to, not just raw awareness. You learn to feel a racing heart, a trembling muscle, or a wave of discomfort without being swept away by it. You notice the signal and stay steady. That's the witness — the part of you that can observe what's happening inside without being consumed by it.

That capacity of nonjudgmental awareness has a neurological footprint, and it's deeply tied to emotional regulation.

So when people say a consistent movement practice helps them feel more grounded, more in tune with themselves, better at reading their own needs — this is, in part, why. They're not imagining it. They're getting better at a measurable sense.

A sense worth cultivating

Researchers are still exploring the best ways to study this complex sense and its full impact on our health, behavior, and wellbeing. But the through-line is already clear: knowing what's happening on the inside — and meeting it with steadiness rather than reactivity — supports nearly every dimension of how we feel and function.

If you'd like to build this kind of body awareness through a practice designed around you, I offer 1:1 private therapeutic yoga and movement sessions. Reach out anytime.
