Your heart pounds, your chest tightens, your hands tingle and a wave of fear says something terrible is about to happen. Was that a panic attack or an anxiety attack? People use the two terms interchangeably, and search results do the same, which can leave you more confused, and more worried, than before.
This guide explains how the terms differ, which one clinicians actually use, how to tell the experiences apart, how they can be confused with a heart attack, what to do in the moment, and how both are treated. It is general information, not a diagnosis.
In short
- Panic attack is a recognised clinical term. It is a sudden surge of intense fear that peaks within minutes, with strong physical symptoms.
- Anxiety attack is an informal, everyday term. It usually describes anxiety that builds up more gradually, often around a worry or stressor, and tends to be less intense.
- They overlap a great deal, and plenty of people use “anxiety attack” to mean a panic attack. Labels matter less than the pattern and the help you get.
- Both are treatable. Cognitive behavioural therapy (CBT) has the strongest evidence.
- Chest pain or other symptoms that could be a heart attack need urgent medical help. If in doubt, call 112.
The short answer
A panic attack is a defined clinical event. An anxiety attack is a popular phrase that doesn’t have a formal definition in the DSM-5-TR, the American Psychiatric Association’s diagnostic manual.
In everyday use, people tend to mean:
- Panic attack: sudden, overwhelming and physical, often feeling like it comes out of nowhere
- Anxiety attack: a spell of intense worry, tension or dread that builds, often with an identifiable cause
Not every clinician or writer draws the line in the same place. If you are unsure which you had, describe what happened to a doctor rather than worrying about the label.
What is a panic attack?
According to the DSM-5-TR, a panic attack is an abrupt surge of intense fear or discomfort that reaches a peak within minutes, accompanied by at least four of these symptoms:
- Pounding or racing heart
- Sweating
- Trembling or shaking
- Shortness of breath or a feeling of smothering
- A feeling of choking
- Chest pain or discomfort
- Nausea or abdominal distress
- Dizziness, unsteadiness or feeling faint
- Chills or hot flushes
- Numbness or tingling
- A sense of unreality (derealisation) or of being detached from yourself (depersonalisation)
- Fear of losing control or “going crazy”
- Fear of dying
Panic attacks can be expected, triggered by a known fear such as a phobia, or unexpected, appearing without an obvious trigger. Some people have them in their sleep.
A panic attack is not the same as panic disorder. Many people have a single panic attack, or a few, without developing a disorder. Panic disorder is diagnosed when attacks are recurrent and unexpected, and are followed by at least a month of persistent worry about having more attacks or changes in behaviour to avoid them. Our anxiety disorder page explains how these conditions are assessed.
What is an “anxiety attack”?
“Anxiety attack” isn’t a formal diagnosis, but it describes a real experience: an episode of intense anxiety, often building over minutes, hours or even days, usually linked to a worry or stressor. It might include:
- Constant, spiralling worry
- Restlessness, tension or feeling “on edge”
- A sense of dread or being overwhelmed
- Irritability
- Difficulty concentrating
- Tiredness or trouble sleeping
- Physical symptoms such as a racing heart, tight chest, stomach upset, sweating or shaky hands
Many people who say “anxiety attack” are describing exactly this. Others use the phrase for what clinicians would call a panic attack.
Panic attack vs anxiety attack: side by side
| Panic attack | “Anxiety attack” (informal) | |
|---|---|---|
| Clinical status | Recognised term in the DSM-5-TR and ICD-11 | Informal, with no official definition |
| How it starts | Abruptly, often within minutes | Usually builds gradually |
| Trigger | May be unexpected, or tied to a known fear | Often linked to a worry, stressor or situation |
| Intensity | Very intense | Variable, often less intense |
| How long | Peaks within minutes. Most attacks pass in a short time, though you may feel drained afterwards | Can last for hours or days |
| Main feeling | Terror, a sense of impending doom, fear of dying or losing control | Worry, dread, tension, feeling overwhelmed |
| Physical symptoms | Strong and sudden: racing heart, breathlessness, chest tightness, dizziness, tingling | Present but often milder and more drawn-out |
| Afterwards | Exhaustion, and fear of another attack | Lingering tension or worry |
| Linked disorder | Can occur in panic disorder, phobias, PTSD and other conditions | Often seen with generalised anxiety or high stress |
These are generalisations. Real experiences blend, and one person may have both kinds on different days.
Could it be a heart attack?
This is the question that sends many people to the emergency department, and it is a sensible one to ask. Panic attacks and heart attacks can feel alarmingly alike, with chest pain, breathlessness, sweating and a racing heart. You cannot reliably tell the two apart from symptoms alone.
Features that point more towards a heart problem include:
- Pressure, tightness or heaviness in the chest, especially during exertion
- Pain spreading to the arm, shoulder, neck, jaw or back
- Cold sweats, nausea or breathlessness without an obvious fear trigger
- Existing heart disease, diabetes, high blood pressure, smoking, a strong family history, or older age
If you are unsure, or this is your first episode, treat it as an emergency and call 112 or go to the nearest emergency department. Doctors would much rather check and reassure you than miss a heart attack. Once a doctor has ruled out heart and other physical causes, you can handle later episodes with more confidence.
Other physical conditions can mimic anxiety or panic, including an overactive thyroid, heart rhythm problems, low blood sugar, asthma, and the effects of caffeine, alcohol, drugs or some medicines. That is one reason a first episode deserves a medical check.
What causes panic and anxiety attacks?
There is rarely one cause. Common contributors include:
- A sensitive alarm system, shaped by genes, temperament and early experiences. Our guide to why we get anxiety explains how this works.
- Ongoing stress, such as work pressure, money worries or caregiving. See our guide to negative stress.
- Fear of body sensations. Some people become frightened of a fast heartbeat or dizziness, which fuels more fear and then more sensations, a loop that psychologists such as David Clark have described.
- Life changes, loss or trauma.
- Caffeine, nicotine, alcohol and other substances, including withdrawal from alcohol or sedatives.
- Poor sleep and exhaustion.
- Other conditions, such as phobias, social anxiety, depression, PTSD and OCD.
What to do during an attack
Whether it’s called panic or anxiety, these steps help in the moment:
- Remind yourself it will pass. Panic attacks are frightening but are not dangerous in themselves, and they peak and fade.
- Slow your breathing. Breathe in gently through your nose and out slowly through your mouth, with a longer breath out than in. Don’t force deep breaths, since over-breathing can add to dizziness and tingling.
- Ground yourself. Name five things you can see, four you can touch and three you can hear.
- Stay where you are, if it is safe. Escaping can teach your brain that the situation was dangerous. If you must move, do so calmly.
- Don’t fight it. Trying to force the feeling away tends to make it stronger. Let it rise and pass.
- Ask for help, and tell someone you trust what is happening.
- Get urgent help if you suspect a heart attack, if you have chest pain that doesn’t ease, if it is your first episode, or if you aren’t sure. Call 112.
One outdated tip to avoid: breathing into a paper bag. It isn’t recommended, and it can be harmful if the cause is something other than panic.
What to do after
- Note what was happening before it began: situation, thoughts, body sensations, caffeine, sleep.
- Rest and eat and drink something, without alcohol.
- Be kind to yourself. Don’t judge the episode as weakness.
- Avoid building your life around avoiding triggers, which tends to shrink your world over time.
- Speak to a doctor if it has happened more than once, if you fear another attack, or if it is affecting your life.
Treatment that works
Panic and anxiety are very treatable. Typical treatment includes:
- A medical assessment, to rule out physical causes
- Talking therapy. Cognitive behavioural therapy is the best-supported approach, and for panic it often includes interoceptive exposure, deliberately and safely bringing on harmless body sensations so you learn that they aren’t dangerous. Our guide to behavioral therapy for anxiety explains the approach, and our Behavioural Therapy page describes how we use it.
- Medication, where appropriate, prescribed and monitored by a doctor. Some antidepressant-type medicines are used for panic and anxiety. Sedative medicines are generally intended for short-term use only, because they can lead to dependence, as our guide to prescription drug addiction explains. Never start, change or stop a medicine without medical advice.
- Lifestyle support: regular sleep, movement, less caffeine and alcohol, and stress management. See our guides to stress management techniques and exercise for mental health.
- Treatment of related conditions, such as depression, phobias or substance use. Our guide to dual diagnosis explains why treating both together matters.
If your attacks are linked to a specific fear, our guide to how to get rid of a phobia explains how gradual exposure works.
Panic, anxiety and substances
Many people use alcohol, cannabis or sedatives to cope with attacks. Relief is brief, and over time it often worsens anxiety and can lead to dependence. Stopping after regular use can itself trigger severe anxiety, so talk to a doctor before cutting down. Our guides to alcohol use disorder vs heavy drinking and alcohol withdrawal explain the risks.
If you are supporting someone
Stay calm and with them, speak slowly, avoid saying “calm down” or “it’s all in your head,” encourage slow breathing and grounding, and don’t leave them alone. Call 112 if you suspect a heart problem or you aren’t sure. Our guide to how to deal with a person with anxiety and depression explains what helps and what doesn’t.
When to get professional help
Speak to a doctor, psychiatrist or clinical psychologist if:
- It is your first attack, or you have chest pain or other worrying physical symptoms
- Attacks are recurring, or you fear having another
- You are avoiding places or activities because of them
- Anxiety is affecting your sleep, work or relationships
- You are using alcohol, drugs or sedatives to cope
- You feel hopeless or numb
If you feel hopeless or are having thoughts of self-harm, please reach out now. You are not alone. In India, the free national tele-mental-health helpline Tele-MANAS (14416) offers support, and in an emergency you can call 112. Our guide to how to tackle mental health issues explains who to see and what to expect.

Frequently asked questions
What is the difference between a panic attack and an anxiety attack?
“Panic attack” is a recognised clinical term for a sudden surge of intense fear that peaks within minutes. “Anxiety attack” is an informal phrase, usually describing anxiety that builds more gradually, often around a stressor, and tends to be less intense. They overlap, and many people use the terms interchangeably.
Is an anxiety attack a real thing?
The experience is real, but “anxiety attack” isn’t a formal diagnosis in the DSM-5-TR. Clinicians usually describe it as a period of intense anxiety, or sometimes as a panic attack.
How long does a panic attack last?
Panic attacks usually peak within minutes and then fade, though you may feel shaky and exhausted afterwards. Anxiety that builds up around a worry can last much longer, sometimes hours or days.
Can a panic attack cause a heart attack?
Panic attacks are frightening, but they are not themselves dangerous. They can feel very like a heart attack, though, and the two can’t reliably be told apart from symptoms alone. If you are unsure, or it’s your first episode, call 112.
How do I stop a panic attack?
Remind yourself it will pass, breathe slowly with a longer breath out, ground yourself by naming things you can see, hear and touch, stay where you are if it’s safe, and don’t fight the feeling. Treatment with CBT can reduce attacks over time.
Is panic disorder the same as having a panic attack?
No. Many people have a panic attack without developing panic disorder. The disorder involves recurrent unexpected attacks plus ongoing worry about more, or changes in behaviour to avoid them.
Can anxiety attacks happen at night?
Yes. Some people wake from sleep in a panic attack. It can be very frightening, and it is worth discussing with a doctor.
Do I need medication?
Not always. Many people recover with therapy, such as CBT. Medication is an option, particularly for more severe or persistent symptoms, and should be decided with your doctor.
This article is for general information and isn’t a substitute for professional medical advice, diagnosis or treatment. If you think you may be having a heart attack, call 112 immediately.
