How long does a panic attack last?

Clinical guidance describes an attack peaking quickly — within one to ten minutes — with the peak lasting roughly five to ten minutes unless it is constantly rekindled. Many people feel shaky or drained for a while afterwards. The important part of that description is the exception: an attack is extended by what keeps restarting it.

Can you faint during a panic attack?

It is unlikely, and for a reason worth knowing. Fainting happens when blood pressure drops. A panic attack does the opposite — heart rate and blood pressure go up. Clinical guidance describes the system producing a panic attack as the opposite of the one that produces fainting, which is why the feeling of being about to faint so rarely turns into actually fainting.

What should I do when a panic attack starts?

Stop trying to stop it, which is the counterintuitive bit. Fighting the attack is itself a way of feeding it. Sit down somewhere if you can, let your out-breath get longer than your in-breath, and let it peak — it is going to anyway, and it comes down on its own. Avoid checking your pulse and scanning for the next symptom, because that is what rekindles it.

Is a panic attack dangerous?

The attack itself is a false alarm rather than a physical emergency, and it ends on its own. That said, several of its symptoms — chest pain, breathlessness, a racing heart — genuinely overlap with conditions that do need urgent care. If you have not had chest pain assessed before, get it checked. Having panic attacks does not protect anyone from also having something else.

Why do panic attacks wake me up at night?

Night-time panic attacks are recognised and are described as especially frightening because they arrive with no obvious trigger — you wake already in one. They are not a sign that something worse is happening. They tend to be more disorienting simply because you have no context for them on waking.

When do panic attacks become panic disorder?

Panic attacks on their own are not a psychiatric condition — they are common, and roughly one in five people experience one at some point. It becomes panic disorder when attacks recur and you develop a persistent fear of having another, or start changing what you do to avoid them. That pattern is very treatable, and worth taking to a doctor rather than managing alone.

What to Do During a Panic Attack

A panic attack is a false alarm — the fight-or-flight response firing when there is nothing to fight or flee. Clinical guidance describes it peaking within one to ten minutes, with the peak itself lasting roughly five to ten minutes unless it is repeatedly rekindled. That last phrase matters, because rekindling is the part you have some influence over: checking your pulse, scanning for the next symptom, and fighting to make it stop all feed it. One fear worth retiring immediately is fainting, which is unlikely during panic because the physiology running an attack is the opposite of the one that makes people faint. None of this is a reason to ignore chest pain you have not had checked before. But if you already know these are panic attacks, the most useful thing is to stop trying to end it and let it do what it does anyway.

If you are in one right now: it peaks within about ten minutes, and it comes down on its own. You do not have to do anything clever. Scroll to the list if reading is hard at the moment.

What is actually happening

A panic attack is the fight-or-flight response firing when there is nothing to fight or run from. Clinical guidance puts it plainly: it is a false alarm — like a fire alarm going off when there is no fire.

Everything you are feeling is that system doing its job, in the wrong context. The racing heart, the fast breathing, the sweating, the urge to get out — all of it is a body preparing to deal with a danger that is not there.

The symptoms clinicians list include a racing or pounding heart, sweating, shaking, shortness of breath, choking sensations, chest pain or pressure, nausea, dizziness, tingling or numbness, hot flushes or chills, a sense that things around you are unreal or that you are detached from your body, thoughts of losing control, and fear of dying.

That last one is on the clinical list. It is a symptom of the attack, not a piece of information about your situation.

How long it lasts

This is the most useful thing to know, and it is specific.


Time to peak	1 to 10 minutes
How long the peak lasts	About 5 to 10 minutes — unless constantly rekindled
Afterwards	Often shaky, drained or on edge for a while

That exception is the part worth sitting with. An attack has a natural shape and it comes down. What extends it is anything that keeps restarting the alarm.

Things that rekindle it: checking your pulse, scanning your body for the next symptom, searching what is happening to you, fighting to make it stop, and asking repeatedly whether you are okay. Each one is understandable and each one tells the alarm system there is still something to be alarmed about.

You are very unlikely to faint

This fear is almost universal during attacks, and it is worth retiring properly, because the reason is mechanical.

Fainting happens when blood pressure drops. A panic attack does the opposite — heart rate and blood pressure go up. Clinical guidance describes the physiological system producing a panic attack as the opposite of the one that produces fainting.

So the feeling of being about to pass out is real, and it is coming from something other than being about to pass out.

What actually helps

The theme is: stop adding to it, and let it do what it is going to do anyway.

Stop trying to stop it. This is the hardest one and the most useful. Fighting the attack is a way of confirming to yourself that something dangerous is happening.
Sit down if you can. Not because you will faint, but because it removes one thing to manage.
Make the out-breath longer than the in-breath. Slow out, longer than feels natural. It will not end the attack and it does settle the body.
Do not check your pulse. Nothing you find there will reassure you for more than a few seconds.
Let it peak. It is going to. Waiting it out is not giving up — it is the thing that actually works.
Name it, once. “This is a panic attack. It peaks and it passes.” Once, not as a chant to argue with.
Afterwards, do not flee the place. If you can stay a few minutes after it settles, you avoid teaching yourself that the place was the problem.

When to get it checked anyway

This matters more than the rest of the page.

Several panic symptoms — chest pain, breathlessness, a pounding heart — overlap with conditions that need urgent care. Clinical guidance notes directly that the symptoms can look like a medical condition and that people seek emergency assistance.

If you have never had chest pain assessed, get it assessed. Go to an emergency department or call your local emergency number for chest pain that is new, severe, spreading to the arm or jaw, or accompanied by breathlessness you have not had before.

Being someone who has panic attacks does not protect you from also having something else. Nothing here is a reason to talk yourself out of care.

Attacks that wake you

Panic attacks that happen during sleep are recognised and described as particularly frightening, because they come with no obvious trigger — you simply wake already in one.

They are not a sign of something worse. They are more disorienting mainly because there is no context to attach them to on waking. Our guide on waking at 3am covers the broader problem of the small hours, and much of it applies afterwards.

When it is panic disorder

Panic attacks by themselves are not a psychiatric condition, and they are more common than people assume — roughly one in five experience one at some point in their lives, with a much smaller proportion going on to panic disorder.

The line is not the attacks. It is what grows around them: a persistent fear of the next one, and changing what you do to avoid it. That avoidance is what turns a frightening experience into a shrinking life.

It is also very treatable. The strongest evidence is for CBT, and specifically for approaches that involve deliberately bringing on the feared sensations in a controlled way so they stop being frightening — which is emphatically a thing to do with a clinician rather than alone. Our guide on talking to a doctor covers how to raise it.

If the pattern you recognise is less sudden terror and more constant low-level dread, the guides on managing mild anxiety and googling your symptoms may fit better.

Afterwards, write down what happened

Not during. Afterwards, when it has settled.

Two things are worth having: roughly when it happened, and what was going on beforehand. Panic that seems to come from nowhere usually turns out to have some pattern once there are a few instances written down — a time of day, a level of tiredness, a kind of situation.

That matters for a specific reason. Memory is unreliable about this in a known direction: you will remember the worst attack and the most recent one, and those two will stand in for all of them. Our guide on why you cannot remember how you felt goes into why.

Logging it in a few seconds afterwards, as you can in Moodify, gives you something concrete to show a doctor instead of trying to describe it from memory in a short appointment.
