The first thing most people want to know is whether something is wrong with them. So let’s say it clearly: what happens in a panic attack is not a malfunction. Every part of it is a system working correctly — on the wrong information.

The system is the fight-or-flight response. Your body has a mechanism for getting you out of danger fast, and the research behind this program describes it as a ‘sudden autonomic discharge’ whose purpose is ‘to prepare the body to engage in protective behaviors of fleeing, fighting, or freezing.’¹ That mechanism is old, it’s fast, and it isn’t optional.

When it fires, a specific set of things happens, and each one has a job:

• Your heart speeds up and beats harder. Blood has to get to the large muscles quickly. This is the symptom people find most frightening and it is the most straightforwardly useful one.
• Your breathing changes. Faster, shallower, higher in the chest. More oxygen in, more carbon dioxide out — sensible if you’re about to run.
• Blood moves. Away from the skin and the extremities, towards the muscles. Hence cold or tingling hands, and hence the pallor other people sometimes notice.
• You sweat. Cooling, in advance of exertion that hasn’t happened yet.
• Your senses sharpen and your attention narrows. Useful for spotting a threat. Deeply unpleasant when there isn’t one, because the narrowing lands on your own body.

Every item on that list is your body getting ready to move. None of it is something going wrong.

So why does it fire when there’s nothing there? Because the alarm system is built to be fast rather than accurate. A smoke detector that goes off at burnt toast is annoying; a smoke detector that waits for certainty is useless. Yours is set the same way, and it’s meant to be.

That’s what a false alarm means here. Not that the feelings are imagined — they are as real as anything gets — but that the thing being responded to isn’t a threat.

This program does not try to switch the alarm off. That’s worth saying at the start, because it’s probably what you came for. You can’t decide not to have an adrenaline response, and every technique that promises to control one tends to make things worse — for a reason that gets its own lesson.

What changes is something else: what the alarm means to you when it goes off. That sounds like a small target, but it turns out to be the whole thing.

One thing to be clear about before you start. This is a compressed, self-guided version of a treatment that normally runs with a therapist, and it’s the weaker version of it. It also leaves out one component on purpose — deliberate symptom provocation — because it isn’t safe to do unsupervised, and Lesson 11 explains what stands in for it. What’s left still works: panic responds to this kind of program better than almost any other anxiety problem.
