How long does a panic attack last?

Panic attack symptoms usually build to a peak within about ten minutes and then ease off, though you may feel shaky or tired afterward. Knowing it is time-limited — that it crests and fades — is part of what lets you settle while it runs its course.

Why does slow breathing help during a panic attack?

On each exhale the vagus nerve slows the heart — the 'vagal brake.' A slow breath with a longer exhale keeps you in that calming phase longer, nudging the body away from the 'fight-or-flight' alarm toward 'rest-and-digest.' Breathing is the one part of the stress response you can steer consciously.

How to calm down from a panic attack with your breath

A panic attack feels like it will never end — but it peaks and passes. Your breath is the one part of the surge you can take hold of, and slowing it down helps you ride the wave as it crests and fades.

How do you calm down from a panic attack?

Slow your breathing and make the exhale longer than the inhale. A physiological sigh — two inhales through the nose, then one long exhale out the mouth — can take the edge off within about a minute. You are not switching the attack off; you are riding the wave, which peaks within minutes and then passes. Naming what's happening ("this is a panic attack, it will pass") helps the breathing do its work. [1]

Why does the breath reach a panic attack?

A panic attack is a sudden surge of the body's alarm system — racing heart, fast shallow breathing, tightness, dizziness — even when there's no real danger. Most of that surge runs on its own; you can't decide to slow your heart. But breathing is the one autonomic function you can steer, and it's wired to the rest. On each exhale, the vagus nerve slows the heart (the "vagal brake"), and a longer exhale keeps you in that calming phase longer — nudging the body out of fight-or-flight. You can even feel your pulse ease on the out-breath; that rise-and-fall is respiratory sinus arrhythmia. In one study, a few minutes of breathing that emphasised a slow, extended exhale lowered arousal and improved mood more than other practices. [2]

A breath to use when it hits

1. If you can, name it to yourself: "This is a panic attack. It peaks and it passes."

2. Take two inhales through the nose — a normal breath in, then a small top-up.

3. Let it out slowly through the mouth, as long and unhurried as you can — the long exhale is the calming part.

4. Repeat for a few rounds, then settle into slow breathing (in for about 4, out for about 6) until the wave eases.

5. Let your feet feel the floor. You don't have to make it stop — you only have to breathe through it.
