Start here if it is happening now
Make your out-breath longer than your in-breath, and keep it that way for about three minutes. That is the whole of panic attack breathing in one line, and the timer above is already set to do exactly that. Press Begin, watch the circle, and let it lead. You do not have to read the rest of this page.
You probably cannot concentrate on counting right now, and you do not need to. The circle grows while you breathe in and shrinks while you breathe out, and there is a quiet tone at each change. Let the shape do the counting for you. If you lose the rhythm, rejoin at the next inhale. Nobody does this cleanly during an attack, and doing it messily still works.
Two things matter more than doing it neatly. The first is that the exhale runs longer than the inhale. The second is that you are not holding your breath at any point. Holding feels like the natural thing to do when your chest is tight, and it is the one part worth avoiding here. The reason is a few paragraphs down, and it is not urgent — the timer is.
How to do it
This pattern is called cyclic sighing. It copies the shape of the sigh your body produces on its own every few minutes without asking you. Two seconds in, one more second in, six seconds out. That is the whole thing.
1. Put your back against something
A chair, a wall, the floor, the side of a bath. You are not trying to sit correctly. You are trying to give your body one less thing to hold up, and giving yourself a physical edge to feel is useful when the room has started to feel unreal.
2. Breathe in through your nose for about two seconds
Not a big dramatic breath. A normal one, through the nose, into the lower part of your chest and belly. If your nose is blocked, use your mouth — this is not the part to get stuck on.
3. Take a second, shorter sip of air on top
Without letting the first breath out, add a small top-up inhale of about one second. It feels a little odd the first few times. That oddness is useful: it is a distinct physical action, so it is hard to do absent-mindedly while your thoughts are racing.
4. Let it all out through your mouth, slowly, for about six seconds
Unhurried, like fogging a window rather than blowing out a candle. This is the long part and it is the part that does the work. If six seconds is too long today, make it four and lengthen it later.
5. Go straight into the next breath
Do not hold at the bottom and do not hold at the top. The cycle runs continuously: in, top up, long out, in again. One cycle takes nine seconds, so you will do roughly twenty of them in three minutes.
6. Stay with it after you feel better
The urge to stop the moment the worst of it passes is strong. Give it the remaining time anyway. The tail end of an attack is where people most often talk themselves back into one, and having something to do with your attention helps.
Why no breath-holds
Most breathing techniques you will find for anxiety contain a hold. 4-7-8 holds for seven seconds. Box breathing holds twice per cycle. Both are good patterns, and this site has timers for both. Neither is the default on this page, and the reason is specific.
When you hold your breath, carbon dioxide builds up in your blood. In panic research, breathing in extra carbon dioxide is not a side effect to be managed — it is a deliberate method. A 2025 meta-analysis of 35% carbon dioxide panic-induction studies, published in the Journal of Psychopharmacology, states the premise plainly: "A brief inhalation of 35% CO2 triggers subjective fear and physiological responses occurring during naturally occurring panic attacks." Carbon dioxide is used in that work precisely because it reproduces the suffocation-like feeling and the surge of fear that people describe during a real attack. It is one of the standard ways to study panic in a laboratory.
That is not the same as saying a four-second hold will hurt you. It will not. A voluntary hold in a chair is a very long way from a carbon dioxide challenge in a study. But when you are already frightened, already feeling short of breath, and already scanning your own chest for evidence that something is wrong, a hold asks you to sit inside the exact sensation you are trying to move away from. A pattern with no holds simply removes that question. That is the whole argument, and it is a preference rather than a prohibition.
There is a second reason worth knowing, and it cuts the other way. During an attack many people over-breathe without realising it, which lowers rather than raises carbon dioxide. Meuret and colleagues randomly assigned thirty-seven people with panic disorder either to breathing training guided by their own carbon dioxide readings (twenty of them) or to a waiting list (the other seventeen), in a 2007 study published in the Journal of Psychiatric Research. Before any treatment began, they reported, "The majority of patients' (n=26) initial values of pCO2 were in a hypocapnic range" — below 35 mmHg, sitting low at rest, with no attack under way. Among those who went through the training, "Mean pCO2 increased from hypocapnic to normocapnic levels over the course of treatment and remained normocapnic at follow-up." That was a small trial of one specific biofeedback protocol, not a test of this timer, and it does not show that a long exhale does the same thing. It is simply why slowing the whole breath down is a more sensible first move than holding it.
What a panic attack is, and what it is not
The clinical literature is unusually clear about the shape of it. The StatPearls clinical review of panic disorder, hosted on the National Library of Medicine's Bookshelf, states that "Panic attacks are defined by the Diagnostic and Statistical Manual of Mental Health Disorders (DSM) as 'an abrupt surge of intense fear or discomfort' reaching a peak within minutes." A 2023 narrative review in Frontiers in Psychiatry lists what arrives with it: "PAs are characterized by multiple physical symptoms including a pounding or racing heart, sweating, dyspnea, weakness or dizziness, feeling hot or cold chills, tingling or numbness in the hands, chest pain, or stomach pain." Add a sense of unreality and the fear that you are losing control or dying, and you have most of what people describe.
Two things follow from that definition that are worth holding onto.
It peaks within minutes. Whatever this feels like, it has a shape, and the steepest part of that shape is short. It does not build forever. Part of what makes an attack so frightening is the belief that it will keep escalating until something breaks, and the definition itself says otherwise.
The symptoms are not the thing you are afraid they are. The StatPearls review puts patient education at the center of treatment: "The patient needs a thorough education on the disorder and understands that the symptoms are not life-threatening." A racing heart during an attack is not a heart attack. Feeling unable to get a full breath is not the same as not getting enough air. The sensations are real and they are horrible, and they are not evidence of the emergency your body is insisting is happening.
Before you take any of that as reassurance, read this. If you have never had a panic attack before, or you are having chest pain, or this feels different from your usual attacks, get it looked at today. Panic symptoms overlap with symptoms that need urgent medical attention, and no breathing exercise and no website can tell the difference between them. Only someone who can examine you can. Being checked and told it was panic is a good outcome rather than a wasted trip, and it is exactly the kind of thing urgent care is for.
A panic attack is also not the same thing as panic disorder. Panic disorder is a diagnosis, and the StatPearls review sets out the threshold: it can be made when "recurrent unexpected panic attacks are happening, followed by one month or more of persistent concern over having more attacks, along with a change in the behavior of the individual" to avoid whatever they blame for the attack. A single attack, or attacks that only happen in an obviously frightening situation, is not that. Only a clinician can tell you which you have. A website cannot, and this one is not trying to.
A grounding add-on: 5-4-3-2-1
Some people find that focusing on breathing during an attack makes things worse, because breathing is where the frightening sensations live. If that is you, a grounding breathing exercise that points your attention outward instead of inward is a better fit. You may have been shown a version of this already.
Between breaths, or instead of them, name:
- Five things you can see. Say them silently or out loud. A door handle. A crack in the paint. Your own shoe.
- Four things you can feel. The chair under you, the floor under your feet, fabric against your arm, the temperature of the air.
- Three things you can hear. Traffic, a fan, your own breathing.
- Two things you can smell. If you cannot smell anything, name two smells you like instead. It still works.
- One thing you can taste. Or one slow sip of water.
Pair it with the timer if you like: run the pattern above and name one item on each exhale. The point is not the list. The point is that naming things in the room takes deliberate attention, and deliberate attention is difficult to give to a catastrophic story at the same time.
When to use this, and when not to
Good times to use it. During an attack, once you are somewhere you can sit. In the twenty minutes afterwards, when you are shaky and drained and your thoughts are still circling. Before something you know sets you off. And — most usefully of all — once a day when nothing is wrong, so the rhythm is familiar enough to find when something is.
Times to do something else. If you are driving, walking near traffic, in water, on a ladder, or anywhere that closing your eyes and slowing down would be dangerous, stop and get somewhere safe first. If breathing exercises have reliably made your attacks worse in the past, believe your own experience over this page. If you are in crisis, use the numbers at the top of this page, not the timer.
Who should be careful
Cyclic sighing has no breath-holds and no fast breathing, which makes it one of the gentler patterns on this site. The switcher above, though, gives you access to patterns that do contain holds and one that is deliberately fast. Those carry real cautions, so they are set out here rather than buried.
- Any pattern with a breath-hold — 4-7-8, box breathing, triangle breathing — deserves a conversation with your doctor first if you are pregnant, have a cardiovascular condition or uncontrolled high blood pressure, have epilepsy, have a respiratory condition such as asthma or COPD, have glaucoma, are recovering from surgery, or have panic disorder. Shorten or drop the hold if it makes you tense.
- The energizing pattern is fast, rhythmic breathing. It is not a calming technique and it is the wrong choice during a panic attack. Never do it in water, in a bath, while driving, or standing up. It carries the same cautions as the breath-hold patterns above, and the timer will ask you to acknowledge them before it starts.
- Any pattern at all should be stopped if you feel faint, get pins and needles in your hands or face, get a headache, or feel more panicked rather than less. Go back to breathing normally and let it settle. None of these techniques should be pushed through.
- If you have a heart or lung condition, or you are on medication that affects your breathing or blood pressure, ask the clinician who knows your history before making any of this a routine.
What the evidence shows
Honestly: less than the internet implies, and enough to be worth three minutes of your time.
The most directly relevant trial is a randomized, controlled, remote study run at Stanford by Balban and colleagues and published in Cell Reports Medicine in 2023. It enrolled 108 people and compared three five-minute daily breathing practices against five minutes of mindfulness meditation over one month; on average, participants completed around eighteen to twenty of the twenty-eight days. In their own words: "Breathwork, especially the exhale-focused cyclic sighing, produces greater improvement in mood (p < 0.05) and reduction in respiratory rate (p < 0.05) compared with mindfulness meditation." Their summary of what that adds up to is deliberately modest: "Daily 5-min cyclic sighing has promise as an effective stress management exercise."
Note what that study was and was not. It measured mood and physiological arousal over a month of daily practice, in a sample recruited mostly from an undergraduate psychology class. It was not a trial of stopping an acute panic attack, and it was not a trial in people with panic disorder. Nobody has shown that this pattern aborts a panic attack, and this page does not claim it does. What it offers is a rhythm to follow while the peak passes, which is a smaller and more truthful claim.
The reasoning for avoiding holds rests on a separate body of work, linked in the breath-hold section above: inhaled carbon dioxide is used deliberately to provoke panic-like states in research, and people with panic disorder have been measured sitting at low resting carbon dioxide levels that rose to normal when a treatment targeted them. That is a reasonable basis for preferring a hold-free pattern in the moment. It is not evidence that holds are harmful, nobody has compared holds against no-holds during an actual attack, and none of it should be read as more than a sensible default.
If breathing exercises alone are not moving things, that is expected, and it is worth knowing what the actual treatments are. For panic disorder specifically, the StatPearls review states that "SSRIs are considered the first-line treatment option for patients with panic disorder", and that "Psychological interventions consist of cognitive-behavioral therapy." No breathing pattern appears on that list, and none of this page is an argument for using a timer instead of either of them. A timer is a tool for a bad ten minutes. It is not a treatment.
When to seek help
Talk to a doctor or a mental health professional if any of these are true:
- You have had more than one unexpected attack, and you have started worrying about the next one.
- You are avoiding places, people or situations to reduce the chance of an attack.
- Attacks are waking you from sleep, or happening several times a week.
- You are drinking more, or using anything else, to keep them away.
- You are having thoughts of harming yourself. Use the numbers at the top of this page today, not eventually.
- Something about the physical symptoms is new, or different from your usual pattern.
Asking for help for panic is not an overreaction. It is one of the more treatable things a person can bring to a clinician, and the people who get better usually got assessed rather than waiting it out alone.
Common questions
How long does a panic attack usually last?
A panic attack reaches its peak within minutes. That peak is short, even though it does not feel short while you are in it. The tiredness and shakiness afterwards can last much longer than the attack itself, sometimes for the rest of the day. Three minutes of slow breathing is chosen to cover the worst of the peak, not to end the whole experience.
Should I hold my breath during a panic attack?
Not as a first choice. Holding your breath raises the carbon dioxide in your blood, and inhaled carbon dioxide is used deliberately in research as a way to bring on panic-like states in people who are prone to them. That is an argument for choosing a pattern with no holds when you are already in an attack, not proof that a four-second hold will harm you. If breath-holds feel fine to you and a clinician has taught you one, keep using it.
Can I use 4-7-8 or box breathing instead?
Both are good patterns and both contain holds, which is why neither is the default here. For everyday winding down, use whichever you like. In the middle of an attack, a hold is the part most likely to make your chest feel tighter and pull your attention onto the sensation you are trying to move away from. If you want a hold-free alternative to cyclic sighing, extended exhale breathing is four seconds in and six seconds out with nothing held.
What if the breathing makes me feel worse?
Stop, and do not treat that as a failure. For some people, paying close attention to breathing is itself uncomfortable, because breathing is where the frightening sensations are. If that is you, try the 5-4-3-2-1 grounding exercise on this page instead, which puts your attention on the room rather than on your body. Walking, cold water on your wrists, and phoning someone are all reasonable things to do instead of a timer.
Is a panic attack the same as panic disorder?
No. A panic attack is a single episode. Panic disorder is a diagnosis that requires recurrent unexpected panic attacks followed by a month or more of persistent worry about further attacks, or changes in behavior to avoid them. Plenty of people have a panic attack once and never have another. Only a clinician can make the diagnosis, and this page cannot.
How often should I practice when I am not panicking?
Once a day for five minutes is enough, and practicing when you are calm is what makes the pattern usable when you are not. A rhythm you have never rehearsed is hard to find in the middle of an attack. Missing days does not undo it, there is no target to hit, and there is nothing to buy on this page.
