The Window of Tolerance

When something overwhelms us, the nervous system has two ways out, up into alarm, or down into shutdown. Between them is a band where you can still think and still feel. The work is to widen it.

When the nervous system reads danger, it takes us out of our thinking selves in one of two directions. Up, into hyperarousal, the racing, defended, fight-and-flight end. Or down, into hypoarousal, the numb, flat, shut-down end. (How it does that, and why, is a story of its own.) Between those two is a band worth knowing well.

Dan Siegel called it the window of tolerance; Pat Ogden and her colleagues carried it into trauma work, and it is Janina Fisher's drawing of it that most clinicians keep on the wall. Inside the window, feelings and reactions stay tolerable. You can think and feel at the same time, both at once, not one cancelling the other, and what you do adapts to fit the situation actually in front of you.

After trauma the nervous system stays braced for danger and never quite stands down, so the smallest thing can throw you clean out of the window, up or down, and you can spend years veering between the two. The signs of each are worth knowing in yourself.

Tap each to open it.

Signs of chronic hyperarousal +

emotional overwhelm · panic · impulsivity · hypervigilance · defensiveness · feeling unsafe · reactive · angry · racing thoughts

Signs of the window of tolerance +

feelings tolerable · think and feel at once · reactions fit the moment

Signs of chronic hypoarousal +

numb or "dead" · passive · no feelings · no energy · can't think · disconnected · shut down · "not there" · ashamed · can't say no

Each of those three cards describes a nervous system state on its own. The next graph shows the system operating over time as we respond to the world around us. You may find you spend more time in one state than the others.

One life, moving through time, riding inside the window, thrown up into hyperarousal, plunging into hypoarousal, and slowly finding its way back in. Signs after Janina Fisher (2008), drawing on Ogden, Minton & Pain (2006) and Siegel's window of tolerance (1999).

The goal was never to stop having a nervous system. It is to widen that band in the middle, so your reaction stays proportionate to what is in front of you. A level-two thing gets a level-two response, not a level-two-hundred one. Drag the window below and watch what happens to the very same reactivity.

Hyperarousal — fight / flight

window of tolerance feelings tolerable · think and feel at once · reactions fit the moment

Hypoarousal — freeze / shutdown

Narrow narrow

The dot is the same movement throughout. Widen the window and the very same reactivity settles inside it, and the signs at either edge ease off.

A narrow window means small things tip you straight out of it. A wider one means more room to feel activated without losing your thinking brain. That is the work, a wider window of opportunity to gain control before the nervous system takes over the driving. So when it happens again, and it will, you have somewhere to stand: notice what the body is doing, breathe yourself back into the room, and only then weigh what is actually there.

And the margin widens.

Living inside a wider window

If your window feels narrower than you'd like, that is something we can work on together.
