How to Stop a Panic Attack: The Science-Backed Protocol
How to stop a panic attack using physiology, not willpower: why fighting panic backfires, the exhale-first breathing method, and how to stop attacks returning.
Do this first, read later
- 1Stop trying to force the panic away. Allowing it lowers the second wave of adrenaline.
- 2Make your exhale longer than your inhale (4 seconds in, 6 to 8 seconds out).
- 3Use cold: hold something cold or splash cool water on your face.
- 4Shift attention from inside your body to details in the room.

What "stopping" a panic attack really means
Once adrenaline has been released, no technique can remove it from your bloodstream instantly. What you can do is stop adding more. Most panic attacks that feel endless are actually a first surge followed by fresh waves of fear about the sensations. Interrupting those follow-up waves is what shortens an attack, and it is realistic to feel noticeably better within a few minutes.
So the aim is not "make every sensation disappear right now". It is "stop fueling the alarm and let it wind down". That shift in goal, on its own, often reduces the intensity.
The panic cycle: why attacks build on themselves
The most influential psychological model of panic, published by David Clark in 1986, describes a loop. A body sensation such as a skipped heartbeat, dizziness, or tight chest is noticed. It is interpreted catastrophically: "I'm having a heart attack", "I'm going to faint", "I'm losing control". That interpretation triggers fear, fear releases adrenaline, adrenaline intensifies the sensations, and the stronger sensations seem to confirm the catastrophe.
Every effective technique for stopping a panic attack breaks this loop at one of its links: calming the body so sensations weaken, correcting the interpretation so the fear drops, or moving attention away so the sensations are not constantly monitored. The protocol below works on all three.
The 5-step protocol
Work through these in order. The whole sequence takes about three to five minutes.
- Acknowledge: "This is a panic attack. It is adrenaline. It is not dangerous and it will pass." Say it even if you do not fully believe it yet.
- Allow: stop trying to escape the feeling. Tell yourself you will let the sensations be there for the next few minutes.
- Exhale: breathe in gently for about 4 seconds and out through pursed lips for 6 to 8 seconds. Continue for at least 90 seconds.
- Cool: hold a cold drink, press a cool cloth to your face, or run cool water over your wrists.
- Redirect: name five things you can see in detail, then return to what you were doing, even slowly.
Why fighting panic makes it worse
When you tell yourself "I have to stop this now or something terrible will happen", your brain hears confirmation that there is an emergency. Struggling against the sensations, tensing up, and scanning your body for signs of danger all keep the alarm running.
Acceptance-based approaches, which are part of modern CBT, teach the opposite: noticing the sensations with curiosity and letting them rise and fall. This is not giving up. It removes the threat signal that sustains the attack. Many people find the peak softens soon after they stop resisting.
Why a longer exhale slows your body down
Heart rate naturally rises a little as you breathe in and falls as you breathe out. This rhythm is called respiratory sinus arrhythmia, and it is driven by the vagus nerve. Making the exhale longer than the inhale spends more of each breath in the slowing phase.
Slowing the overall pace also counters over-breathing, which is behind the dizziness and tingling many people feel. In a 2023 Stanford randomized study, just five minutes a day of exhale-focused breathing improved mood and lowered resting breathing rate more than mindfulness meditation did. That study was in healthy volunteers rather than people with panic disorder, but it supports the same principle.
What about cold water?
Cool water on the face triggers part of the diving reflex, which slows the heart rate. Holding something cold also gives your brain a strong, neutral sensation to focus on. The evidence for cold as a panic treatment is limited, but as a quick, harmless way to interrupt the spiral, many people find it useful. Avoid ice baths or extreme cold, especially if you have a heart condition.
Things that feel helpful but tend to backfire
Some responses bring short-term relief but make future attacks more likely. Researchers call them safety behaviors, because they teach your brain that you only survived thanks to them.
- Leaving the situation immediately every time.
- Always carrying water, medication, or a phone "just in case", and panicking if you forget it.
- Repeatedly checking your pulse or blood pressure.
- Asking others for reassurance over and over.
- Breathing into a paper bag, which is no longer recommended.
How to stop panic attacks from coming back
Getting through one attack is one skill. Reducing how often attacks happen is another, and it is where treatment is most effective. NICE guidelines in the UK recommend a stepped approach: guided self-help based on CBT first, then therapist-led CBT, with SSRI antidepressants as an option. CBT for panic typically includes learning the panic cycle, practicing slow breathing, challenging catastrophic thoughts, and interoceptive exposure: deliberately bringing on mild panic-like sensations, such as by spinning or running on the spot, until they stop feeling threatening.
Benzodiazepines such as alprazolam may stop an attack quickly, but NICE advises against them for panic disorder because they carry risks of dependence and are linked with worse long-term outcomes. Speak to a doctor about what fits your situation.
Breathe with the circle: 4 in, 6 out
Your heart naturally slows a little on every out-breath. Making the exhale longer than the inhale gives your body more of that slowing phase. Keep going for a couple of minutes.
Frequently Asked Questions
Can you stop a panic attack in 30 seconds?
Usually not completely. Adrenaline takes a few minutes to clear. But within 60 to 90 seconds of slow exhale breathing and accurate self-talk, you can stop the second wave, which is often what makes an attack feel endless.
What is the fastest way to calm a panic attack?
For most people it is a combination of a longer exhale than inhale and naming the attack as panic rather than danger. Together they calm the body and remove the fear that keeps the alarm going.
Should I take medication to stop a panic attack?
Only as prescribed by your doctor. Fast-acting sedatives can end an attack but are not recommended for ongoing panic disorder because of dependence risk. Longer-term options such as SSRIs and CBT reduce how often attacks happen.
Does breathing into a paper bag stop a panic attack?
It is no longer recommended. It can lower oxygen levels and is unsafe if the breathlessness is actually caused by a heart or lung problem. Slow, exhale-focused breathing achieves the same goal safely.
Why do panic attacks keep happening even when I know they are harmless?
Knowing is not the same as your nervous system believing. Repeated experience of staying with the sensations without escaping is what retrains the alarm. That is why CBT uses gradual exposure rather than information alone.
