Breathing for Panic Attacks — What to Do in the Moment

← Back to Blog

A panic attack feels overwhelming — racing heart, shortness of breath, dizziness, the sense that something terrible is about to happen. But understanding what's actually happening in your body gives you a powerful tool to interrupt it: your breath.

Why Panic Attacks Happen

A panic attack is your fight-or-flight system misfiring. Your brain triggers an alarm response — releasing adrenaline, speeding up your heart, and tightening your breathing — when there is no actual physical danger.

One of the most common triggers that makes a panic attack worse is hyperventilation. When you breathe too fast and too shallowly during panic, you exhale too much carbon dioxide. This drops your CO₂ levels, which paradoxically causes dizziness, tingling, and a feeling of unreality — making the panic worse.

The solution: slow your breathing down to restore your CO₂ balance and signal to your brain that you are safe.

Step-by-Step: What to Do When Panic Hits

Step 1 — Recognize It

The first thing to do is name it: "This is a panic attack. It is uncomfortable but not dangerous. It will pass." Panic attacks peak within 10 minutes and almost always subside within 20–30 minutes. Knowing this helps you ride it out rather than fight it.

Step 2 — Slow Your Exhale

This is the single most important thing you can do. A long, slow exhale directly activates your vagus nerve and slows your heart rate.

Do this for 3–5 minutes. You will feel your heart rate begin to slow. This is your parasympathetic nervous system taking back control.

Step 3 — Ground Yourself With the 5-4-3-2-1 Technique

While continuing slow breathing, engage your senses to bring your attention back to the present moment:

• 5 things you can see
• 4 things you can physically feel (feet on the floor, clothes on your skin)
• 3 things you can hear
• 2 things you can smell
• 1 thing you can taste

This interrupts the panic spiral by pulling your attention away from your thoughts and into your physical environment.

Step 4 — Box Breathing to Stabilize

Once the acute panic begins to subside (usually after 5–10 minutes of slow breathing), shift to box breathing to fully stabilize:

What NOT to Do During a Panic Attack

• Don't breathe into a paper bag — this is an outdated technique and can be dangerous
• Don't try to take a huge deep breath — this often makes hyperventilation worse. Focus on the exhale, not the inhale.
• Don't fight the feelings — resisting panic amplifies it. Allow it to pass.
• Don't check your heart rate repeatedly — this increases anxiety. Trust the breathing.

Preventing the Next One — Daily Breathing Practice

The best defence against panic attacks is a daily breathing practice when you are not panicking. Regular slow breathing lowers your baseline anxiety, increases your CO₂ tolerance, and trains your nervous system to recover faster from stress responses.

Just 5 minutes of box breathing or 4-7-8 breathing daily significantly reduces panic attack frequency over weeks. Think of it like physical fitness — you train when you're healthy so your body can handle stress when it hits.

When to Seek Professional Help

Breathing techniques are a powerful tool, but if you're having frequent panic attacks, experiencing panic that significantly limits your daily life, or feeling depressed alongside the anxiety, please speak with a doctor or therapist. Cognitive Behavioural Therapy (CBT) combined with breathing practice is highly effective for panic disorder.
