How to Calm a Panic Attack With Breathing (and What to Avoid)

If you are in a panic attack, breathe in gently through your nose for 4 seconds and out slowly for 6, with no holds. Let the exhale do the work. This may take the edge off the wave, but it does not always stop it, and that is normal.

This article gives you a calm, step-by-step method, explains what the research does and does not show, lists what to avoid (including the paper bag), and covers when to get help.

Can breathing calm a panic attack?

Sometimes, and mostly by turning the intensity down, not by switching the attack off. Panic attacks bring a sudden wave of fear with a pounding heart, sweating, trembling, dizziness or trouble breathing. NIMH says attacks often last several minutes, and some last longer (National Institute of Mental Health).

The research on breathing for panic is mixed. A 2003 review found nine studies of breathing training for panic disorder and judged them not compelling enough to say the training clearly works, partly because the methods varied a lot (Meuret et al., 2003). In a 77-person trial, adding breathing retraining to cognitive behavioral therapy gave no extra benefit, and some data pointed to a slightly worse result (Schmidt et al., 2000). A more careful approach, with a handheld device that gave feedback on breathing, helped 37 people with panic disorder more than waiting did, and the gains held at 12 months (Meuret et al., 2008).

The honest summary: slow, gentle breathing is a safe thing to try, and it can give you something to do. It is not a standalone answer for panic disorder.

Why gentle breathing is the safe choice

Panic often pulls your breathing fast and high in the chest. Fast breathing can lower carbon dioxide in the blood, which can bring on tingling, light-headedness and a feeling of unreality. Those feelings then look like more danger, and the wave grows.

A slow pace with a longer exhale works the other way. It slows the rate without forcing big breaths, and it gives your attention a simple job. In a 2026 study of 66 students facing a stressful virtual speech, a breathing pattern with a 3-second inhale and a 6-second exhale stopped the usual rise in heart rate and reported anxiety that the normal-breathing group showed (McAllister et al., 2026). That was a lab task, not a panic attack, so treat it as a clue, not proof.

How to breathe through a panic attack

You can do this sitting, standing or lying down. Keep your eyes open if closing them makes you feel worse.

1. Name what is happening. Say to yourself, "This is panic. It is uncomfortable and it will pass." That one sentence takes some fuel away.
2. Let your shoulders drop and unclench your jaw. This takes about five seconds.
3. Breathe in gently through your nose for about 4 seconds. Small and easy, not a big gulp.
4. Breathe out slowly through your mouth for about 6 seconds. Soft lips, like blowing on hot tea. No holds at the bottom.
5. Repeat for 3 to 5 minutes, or until the wave eases. That is roughly 30 to 50 breaths. If you lose count, just keep the exhale longer than the inhale.
6. Look around and name five things you can see. This grounds you in the room while your body settles.

If a 4-second inhale feels like too much, shorten both counts, for example 3 in and 4 or 5 out. If counting makes you feel more pressured, skip the counting and simply make each exhale a little slower than the last.

What the research shows

• Breathing training for panic, 9 studies: the evidence was not strong enough for a clear verdict, and the study methods varied (Meuret et al., 2003).
• Breathing retraining added to CBT, 77 patients: no clear extra benefit over CBT without it (Schmidt et al., 2000).
• Feedback-guided breathing training, 37 patients: large improvements in panic severity versus a waiting group, maintained at 12 months. It used a device that measured carbon dioxide, so it is not the same as breathing alone (Meuret et al., 2008).
• Stressful speech, 66 students: a longer-exhale pattern and box breathing both blunted the usual stress response, with no difference in thinking performance (McAllister et al., 2026).

The takeaway: gentle breathing is a reasonable tool, the proof for panic specifically is thin, and professional treatment such as cognitive behavioral therapy has the stronger record.

What to avoid

• Breathing into a paper bag. A 1989 study found oxygen dropped sharply during paper bag rebreathing, and the author described three deaths when it was used on people who were short of oxygen or had heart trouble (Callaham, 1989). It is an old habit worth dropping.
• Long breath holds. Holding your breath can feel like air hunger, which is exactly what panic fears.
• Big, forced deep breaths. They can speed things up and leave you dizzy.
• Fighting the feeling. Pushing hard against panic often adds more fear. Aim to ride it out.
• Treating breathing as a test you can fail. If the first try does not work, nothing went wrong. Try again, or switch to grounding.

Who should be careful

• People with panic disorder: avoid breath holds and fast, deep breathing, which can trigger or worsen symptoms. Use only the gentle long-exhale pattern.
• Anyone with chest pain, trouble breathing that does not ease, or a first-ever attack: get medical help right away, because these can have causes other than panic.
• People with asthma or another lung condition: keep every breath easy and unforced, and check with your doctor about what suits you.
• Anyone who feels dizzy, faint or tingly: stop, breathe normally, and sit down.
• Anyone having frequent attacks or avoiding places because of them: please talk to a doctor or therapist. Effective help exists.
