Panic Attack vs Anxiety: How to Tell the Difference and What to Do

Quick answer: Anxiety is persistent, building worry that can simmer for hours or days, usually in response to stress. A panic attack is a sudden surge of intense fear that peaks within about 10 minutes, with strong physical symptoms such as a racing heart, chest tightness and shortness of breath. Panic attacks feel terrifying but are not physically dangerous. If chest symptoms are new, or you are ever unsure whether it is a panic attack, seek medical assessment to be safe.

Key takeaways

Anxiety builds gradually; a panic attack comes on suddenly and peaks within minutes.
Panic attack symptoms include a racing heart, chest tightness, breathlessness, dizziness and a feeling of unreality.
Panic attacks feel frightening but are not physically dangerous — the surge always passes.
Slow breathing, 5-4-3-2-1 grounding and reminding yourself it will pass can ease an attack in the moment.
Recurrent attacks plus a month of worrying about the next one may indicate panic disorder.
Cognitive behavioural therapy with interoceptive exposure is a well-evidenced treatment for panic.

What is the difference between anxiety and a panic attack?

Although people often use the words interchangeably, anxiety and a panic attack are not the same experience. Anxiety tends to be a slow build — a persistent sense of worry, dread or being on edge that can last hours, days or longer, usually tied to a stressor such as work, health or finances. It rises and falls, but rarely feels like an emergency. If you would like a fuller picture of everyday worry, our guide to understanding anxiety and stress is a good starting point.

A panic attack is different. It is a sudden, intense surge of fear that comes on quickly — often out of the blue — and peaks within about 10 minutes before easing (Healthdirect, 2025). Where anxiety simmers, a panic attack spikes. The physical symptoms are strong and can feel overwhelming, which is part of why a first attack is so frightening.

What does a panic attack feel like?

During a panic attack the body’s alarm system fires all at once. Common symptoms include a pounding or racing heart, chest tightness or pain, shortness of breath or a choking sensation, sweating, trembling, dizziness or feeling faint, and nausea (Beyond Blue, 2025). Many people also notice derealisation — a sense that their surroundings are not quite real — or a fear that they are losing control, going mad or even dying.

These sensations are real and deeply unpleasant, but they are the result of a harmless (if dramatic) burst of adrenaline, not a sign that something is physically wrong. Symptoms usually build fast, peak within roughly 10 minutes, and then fade as the adrenaline clears — most attacks are over within half an hour (Beyond Blue, 2025). Knowing this shape — surge, peak, pass — can make the experience feel less bewildering.

Is a panic attack dangerous?

This is one of the most important things to understand: a panic attack is not physically dangerous, even though it can feel life-threatening. The racing heart and breathlessness are your fight-or-flight response switching on when there is no real threat — uncomfortable, but not harmful. The attack will pass on its own, whether or not you do anything.

There is one sensible caveat. Because chest pain, breathlessness and a racing heart can also be signs of a physical problem, new or unfamiliar chest symptoms should always be checked by a doctor if you are ever in doubt. If you have chest pain and think you may be having a heart attack, call triple zero (000) immediately (Healthdirect, 2025). Once a medical cause has been ruled out, it becomes easier to recognise and respond to panic for what it is.

What to do during a panic attack

You cannot always stop a panic attack, but you can ride it out more calmly. When you feel one starting, try the following:

Slow your breathing. Breathe in gently through your nose for a count of four, then out slowly for a count of six. Longer out-breaths help settle the body’s alarm response.
Ground yourself with 5-4-3-2-1. Name five things you can see, four you can hear, three you can touch, two you can smell and one you can taste. This anchors your attention in the present.
Remind yourself it will pass. Tell yourself, calmly, “This is a panic attack. It is uncomfortable but not dangerous, and it will peak and pass.” Fighting the feelings tends to fuel them; letting the wave rise and fall lets it settle faster.
Stay put if you safely can. Leaving the situation can teach your brain that the place was the danger. Where it is safe, wait for the surge to ease before moving on.

When repeated panic attacks may be panic disorder

A single panic attack is surprisingly common — around 40% of Australians will have one or two at some point in their lives (Beyond Blue, 2025). Having an attack does not mean you have a disorder. Panic disorder is diagnosed when panic attacks are recurrent and unexpected, and are followed by at least a month of persistent worry about having another, or by changes in behaviour to avoid situations where an attack might happen (Beyond Blue, 2025).

Around 5% of Australians experience panic disorder at some stage, and roughly 3-4% in any given year (Beyond Blue, 2025). The good news is that it responds well to treatment. If attacks are becoming frequent, or the fear of the next one is shrinking your world, it is worth speaking with a GP or psychologist.

Evidence-based treatment for panic

Panic is one of the more treatable difficulties in psychology. The best-evidenced approach is cognitive behavioural therapy (CBT), which helps you understand the panic cycle, challenge catastrophic interpretations of body sensations, and gradually build confidence that the sensations are safe. You can read more about how it works in our guide to what CBT is.

A key ingredient is interoceptive exposure — deliberately and safely bringing on the physical sensations of panic (for example, breathing quickly or spinning) so your body learns they are not threatening. A large component analysis of CBT for panic disorder found that interoceptive exposure, delivered face to face, was linked to better outcomes (Pompoli et al., 2018), and reviews of anxiety disorders consistently support exposure-based methods (Ougrin, 2011). Our psychologists provide this kind of support through our panic attack treatment in Melbourne, in person and via telehealth.

Frequently asked questions

What is the main difference between a panic attack and anxiety?

Anxiety is persistent, building worry that can last hours or days, usually linked to a stressor. A panic attack is a sudden, intense surge of fear that peaks within about 10 minutes with strong physical symptoms. In short, anxiety simmers while panic spikes.

How long does a panic attack last?

Panic attack symptoms usually build quickly and peak within about 10 minutes, then ease as the adrenaline clears. Most attacks are over within half an hour. The intensity feels alarming, but it is always time-limited.

Can a panic attack harm you?

Panic attacks are not physically dangerous, even though they can feel terrifying. The symptoms come from a harmless surge of adrenaline. That said, if chest pain or breathlessness is new or unfamiliar, have it checked by a doctor, and call 000 if you think you may be having a heart attack.

How do I calm a panic attack quickly?

Slow your breathing with a longer out-breath, try the 5-4-3-2-1 grounding technique, and remind yourself the attack will peak and pass. Avoid fighting the sensations, as resisting them tends to make them stronger. Staying put where it is safe also helps your brain learn there is no real danger.

When should I see a psychologist about panic attacks?

Consider seeing a psychologist if panic attacks are recurring, if you spend a lot of time worrying about the next one, or if you are avoiding places or activities because of them. These can be signs of panic disorder, which responds well to cognitive behavioural therapy. A GP can also help with a referral and a Mental Health Care Plan.
