panic attack. what to do right now

what’s happening in your body

A panic attack is a false alarm. The part of the brain that handles survival decided there was danger nearby and launched everything needed to run: adrenaline, a racing heart, fast breathing, tense muscles. The only problem is that there’s no one to run from. Your body is ready for a fight, and around you there’s a kitchen or a train carriage.

That’s where all the frightening sensations come from:

• Your heart is pounding. Adrenaline drives your heart rate up so the muscles get blood. In a panic attack the heart is healthy and doing exactly what it does on a treadmill.
• You can’t get enough air. The most deceptive one. Breathing speeds up and the carbon dioxide in your blood drops below normal — yet the feeling of being short of air only grows, so you breathe faster still. Right now you have more air than you need.
• Your head spins, your fingers and lips go numb. A direct result of the fast breathing — pure mechanics, taken apart in when you can’t get a full breath. Unpleasant and safe.
• Everything feels unreal. Derealisation is part of the stress response too. It frightens more than anything else here, and your mind is fine.
• It feels like you’re dying. Fear of death is part of the definition of a panic attack. It feels completely real — and it still passes along with the attack.

That isn’t the whole list. The list psychiatrists use runs to thirteen signs: sweating, trembling, chills or a rush of heat, nausea or an unsettled stomach, chest pain, the feeling of being choked, the fear of losing control. Any four of the thirteen are enough for an attack to count as a panic attack. That’s why it looks different in two people, and why “but mine comes without the pounding heart” doesn’t rule it out.

An attack builds fast, in a few minutes, and rolls back just as fast. A panic attack rarely lasts longer than half an hour: the adrenaline simply runs out, and the body can’t hold that state for long.

when to call an ambulance

Everything above describes a panic attack. Before there’s a diagnosis, though, and on a first attack, there’s no way to be sure yet.

Call emergency services — 911 in the US and Canada, 999 in the UK, 112 across Europe — if:

• there’s pressing or burning pain in the chest spreading to the left arm, the neck, the jaw, or between the shoulder blades;
• the pain holds for more than fifteen or twenty minutes, or keeps building;
• there’s sudden breathlessness at rest, particularly if that’s new for you;
• you fainted, rather than just felt faint;
• one side of the body has gone weak, the face has dropped, speech has slurred;
• it’s your first attack ever — especially if you’re over forty, or you have a heart condition, diabetes, or high blood pressure;
• it’s running differently from previous times: longer, stronger, other sensations.

Calling an ambulance for a panic attack is legitimate. Nobody can tell it from a heart attack by sensation alone — chest pain and the fear of dying belong to both pictures, and an ECG takes a minute. There’s a side benefit, too: for a lot of people the fear halves after that first examination, because it finally becomes clear what they are dealing with.

why breathing in particular helps

Breathing is the one automatic process in the body you can reach with your attention. Through it you can get at a reaction you otherwise couldn’t touch.

There’s a specific mechanism at work. On the inhale the heart speeds up, on the exhale it slows down; this is called respiratory sinus arrhythmia, and it shows on an ECG. Which means that if you make the exhale longer than the inhale, the average heart rate goes down, and you can measure it. Everything else follows: the brain gets a signal from the body that there’s no chase, and gradually lets the alarm go.

That’s why most calming techniques make the exhale longer than the inhale; everything else is a detail of rhythm. There are rhythms with equal inhale and exhale too — box breathing and resonance breathing, five seconds each way. There the calm comes from the overall slowing of the breath.

how to do it: the physiological sigh

A technique the body already knows: it does this kind of sigh on its own, several times an hour, to open up the lungs — we’re simply repeating it deliberately. A Stanford study, published in Cell Reports Medicine in 2023, found that five minutes of these sighs a day over a month lifted mood and slowed resting breathing more than the same minutes of meditation. Anxiety came down in both groups alike.

1. Breathe in through the nose — calm, deep, the belly moving forward. About three seconds.
2. Top it up — one more short breath in through the nose, on top of the first. It feels like there’s nowhere left for air to go, but there’s room. One second.
3. Long exhale through the mouth — slowly, without forcing it out. Six seconds, until it runs out.
4. Repeat. Five or six rounds is usually enough, but you can go longer.

Counting is hard in a panic, so the practice at the top of the page holds the rhythm for you. In the app the same thing runs through vibration — you can close your eyes and not look at the screen at all.

what makes it worse

The four things people most often suggest for panic all work against you.

The paper bag. Don't breathe into one. The advice has been around since the last century and even made it into films, but doctors have dropped it: if something else is behind the symptoms — asthma, a heart problem — breathing into a bag lowers your oxygen and does real harm. Slowing the exhale is enough. Clinics’ own pages still carry this advice, and it sits high in search results.

Big breaths one after another. The most common suggestion and the least useful one: inhales in a row with no long exhale make hyperventilation worse. The exhale is what settles things — in the sigh above, the deep inhale works only because an exhale longer than both inhales follows it.

Alcohol. It muffles things for an hour, and the rebound usually arrives as heightened anxiety the next day.

Looking up your symptoms. Any list will hand you a heart attack and a stroke, and the whole thing starts over.

what else takes an attack down

Bring yourself back into the room. Find five things you can see, four you can touch, three sounds you can hear, two smells and one taste. The technique is called 5-4-3-2-1 and it rests on something simple: attention can’t be held on a catastrophe in your head and on the pattern of the wallpaper at the same time.

Cold on the face. Splash cold water on your face, or step out into cold air. The face is the part that matters: cold there slows the heart a little. Holding something cold to your wrists gets suggested a lot — it distracts, but it does nothing for the pulse.

Tell yourself this is panic. Out loud or silently: "this is a panic attack, it will pass". A thing with a name frightens less than a thing without one. It's a working technique from cognitive behavioural therapy.

Stay put if you can. When an attack catches you in a shop or on the underground, the strongest urge is to bolt. If you manage to wait it out, your brain remembers that the place turned out to be safe. If you can't — that happens to plenty of people, and it changes nothing about next time.

what comes after an attack

The attack lets go and you still don’t feel like yourself for a few hours. That is how it should be: the body has just run a sprint.

Wrung out. Weakness, shaking, sometimes a headache. Water, food and an hour with nowhere to be all help.

Shame, especially if it caught you around other people. From the outside it almost always looked far less dramatic than it felt.

The fear that it will happen again. This one sticks around longest — for many people it stays after everything else has gone, and it starts nudging them to avoid the place where it happened. More on that just below.

why one attack invites the next

One mechanism sits between a single attack and panic disorder, and it isn’t complicated.

After a first attack the body stays as it was, but attention shifts: you start listening to your heart. And you find something, because a heart does beat faster sometimes — after stairs, coffee, a stuffy room, a short night. Then the thought arrives: here it comes. That thought triggers a spike of adrenaline, the pulse genuinely jumps, and the thought turns out to be right. The circle closes: a sensation, a thought about danger, fear, the same sensation stronger than before.

So panic disorder runs on the fear of the next attack, and that thought in the middle of the circle is what therapy works on.

if it keeps happening

A single panic attack in a lifetime happens to a great many people — it means nothing on its own. If the attacks come back — and especially if you start arranging your life to avoid them (not taking the underground, not going far from home) — that’s panic disorder, and it has a name, a diagnosis and a well-studied treatment.

The threshold is fairly specific: the attacks recur and arrive unexpectedly, and for at least a month afterwards either the worry about the next one sticks around, or life gets rearranged to avoid it. That month is there to separate a disorder from the ordinary shake-up after one bad episode.

It responds to treatment better than a lot of conditions do. Cognitive behavioural therapy helps the majority, usually within ten to fifteen sessions. Some people need longer, and that's a normal way for it to go. The person to see is a clinical psychologist or psychotherapist; if medication is needed, a doctor will choose it.

Separately: before starting that work it’s worth seeing a doctor once and ruling out physical causes — everything after that goes more calmly. For the acute situations, where waiting for an appointment isn’t the answer, see when to call an ambulance above.
