There is a sense that does not make the list of five. Interoception — the perception of your own internal state. Hunger, thirst, heartbeat, the need for a bathroom, the tightening before you cry, the specific dread that arrives ten minutes before you consciously know something is wrong.
People vary enormously in how much of it they have, and the variation matters more than almost anything else in this work.
What low interoception looks like
Not noticing hunger until you are shaky. Discovering you are exhausted only when you sit down. Being told you look furious and genuinely not knowing. Getting ill the week after the crisis rather than during it. Being asked what you feel in your body and finding a blank where the answer should be.
Most people with this pattern assume they are bad at feelings. That is not it. The signal is being generated; it is not arriving.
Why it gets turned down
Because it was expensive to have. If you grew up somewhere your own state was irrelevant or dangerous to express, attending to it had no payoff and some cost, and attention went outward instead — to the room, the other person, the mood. That trade was correct at the time.
It also happens after pain, after long illness, and after any stretch where you had to function through something. Turning the volume down is what let you keep going.
Why it matters here
Because most of body-based therapy runs on it. A therapist asking what happens in your chest is asking you to read an instrument, and for a lot of people the instrument has been unplugged for twenty years.
This is why blankness in early sessions is so common and so misinterpreted. It is not resistance, and it is not evidence the method is wrong for you. It is the starting condition, and it is often the thing being treated rather than an obstacle to the treatment.
How it comes back
Faster than people expect, and through the side door. Not by trying harder to feel things, which mostly produces frustration, but by noticing small, low-stakes, physically obvious things on purpose.
Temperature is the easiest starting point — most people can tell warm from cold when they cannot tell anxious from tired. After that: the weight of your feet, whether your jaw is touching, whether your breath is high or low, whether you are actually hungry or just at the point in the day when you eat. Three times a day, ten seconds, no conclusions required.
That sounds too small to matter. It is the whole mechanism. You are re-establishing a channel by using it, and it responds to frequency rather than intensity.
The caution
For some people more interoception is not better. In health anxiety, attention to sensation feeds the loop directly — noticing the heartbeat produces the fear that produces the heartbeat. Some autistic people find that turning attention inward is reliably dysregulating rather than informative.
If that is you, this work needs to be led by someone who takes it seriously from the first session rather than treating it as something to push through. Say it out loud in the consult call, and listen carefully to the answer.
