There is the braced one. Shoulders up, sleep thin, everything slightly too loud, a list running underneath whatever else you are doing.

And there is the flat one. The afternoon where starting anything is impossible, where the sofa holds you and the day goes past at a distance.

Between them is a third state, and most people have no word for it at all.

The map is simple. A nervous system moves between mobilised, shut down, and settled while still awake. Mobilised is useful and meant to be temporary. Shutdown follows when it goes on too long. The third is where you are alert and not braced at once, and it is what this newsletter aims at.

I want to be straight about the source. The three state description is associated with polyvagal theory, popular among therapists and disputed among researchers. The anatomy underneath it is contested, and anyone selling you nervous system rewiring deserves suspicion. What survives the argument is the description. Most people recognise all three in their own week, whatever the mechanism turns out to be.

The description is worth having for one reason. You cannot aim at a state you have no name for. Ask most people what they want and they say calm, which usually means the flat one, because it is the only alternative to braced they have had recently. Shutdown is cheap and available. Settled is neither.

Here is what eleven years of illness does. The braced state stops being an event and becomes the baseline, because there has been something to brace for every week of them. Shutdown arrives as the only relief available. The third gets rarer, not because you failed at it, but because it needs conditions that have been in short supply.

Which is the part that matters. The third state is not a skill you lack. It has conditions, and conditions can be arranged. Not reliably, not on demand, and not by breathing in a particular pattern. But more often than nothing, and you have had it this month without noticing.

One boundary. If the flat state is where you live most days, and nothing has registered as pleasant for weeks, that is not a nervous system to manage with a practice. That is a conversation with your doctor, with treatments behind it.

For everything else, the question is less about technique than about evidence:

Today’s Practice

Not a regulation exercise. An investigation, and it works better written down than thought about.

On a hard day, do the first step and nothing else. Naming which state you are in is a complete act, and if the answer is the flat one for the third week running, that is the week to ring your doctor.

What the Research Says

Heart rate variability is the number people reach for here. The variation between heartbeats does track something about how the body regulates itself, and group level research links lower variability with poorer outcomes. The complication is that an individual reading is noisy. Sleep, alcohol, a cold coming on, your age and your sex all move it. Consumer devices use their own undisclosed scoring, so a number from a ring is not a clinical measurement. As a trend over months it may mean something. As a daily verdict on how regulated you are, it mostly tells you that you slept badly.

Everyone’s Talking About

Somatic shaking is having a long moment, and it has a reasonable story behind it. Animals do tremble after a threat passes, and the practice invites you to shake deliberately to discharge what is held. The trouble is evidence. There is very little, almost nothing controlled, and the published work is small and enthusiastic. There is also a serious caution. For people carrying trauma, a practice that deliberately raises intensity without a trained person present can leave you worse. If it feels good, treat it as movement you enjoy. That is a respectable reason to do something.

From the Old World

Indian philosophy got to a three part description a very long time ago, and arranged it as qualities rather than states. Rajas is restlessness, drive, agitation, the quality of being in motion. Tamas is heaviness, inertia, the quality of being stuck. Sattva is clarity and balance, the one in between. The physiology is not the point and the systems are not equivalent. What is striking is that a tradition watching people closely two thousand years ago arrived at the same shape, and gave the middle one a name, which is more than English has managed.

Come Home

Five lines, from whichever state you are in.

One act for today, if you want one. Write down one time this month you felt settled and awake, and what was around you when it happened.

You have not lost the third state. You have been living somewhere that makes it rare, and that is a different problem with different answers.

P.S. Tomorrow, the old world. An Akan word for going back to fetch something you left behind, and why that is not the same as being stuck.
