Quick answer
What is panic attacks?
A panic attack is a sudden episode of intense fear with physical symptoms — racing heart, breathlessness, chest tightness, dizziness and feeling out of control. They peak within minutes and are not dangerous, though they feel frightening. Breathing slowly helps in the moment; recurring attacks may need talking therapy or treatment for underlying anxiety.
Panic attacks feel frightening but are not dangerous
A panic attack is a sudden surge of intense fear or discomfort that peaks within minutes, accompanied by strong physical symptoms. Many people fear they are having a heart attack, stroke, or losing control. Panic attacks are not physically dangerous — but they are very distressing, and recurring attacks can significantly affect daily life.
What happens during a panic attack
Symptoms often come on suddenly and may include:
- Racing or pounding heartbeat
- Chest tightness or pain
- Breathlessness or feeling unable to breathe
- Dizziness, light-headedness, or feeling faint
- Trembling or shaking
- Sweating and hot or cold flushes
- Nausea or stomach churning
- Numbness or tingling in hands and feet
- Feeling detached from yourself or reality (derealisation)
- Fear of dying, losing control, or going mad
Attacks usually peak within 5 to 20 minutes, then fade. Exhaustion afterward is common.
Why panic attacks happen
The body’s fight-or-flight response activates without real danger. Adrenaline surges, causing the physical symptoms. Triggers may include:
- stress and life pressures
- caffeine and stimulants
- lack of sleep
- specific situations — crowds, motorways, public transport
- sometimes no clear trigger
Panic attacks are linked to anxiety and panic disorder (recurrent unexpected attacks plus worry about future attacks), but can occur in anyone.
What to do during an attack
In the moment:
- Remind yourself — “This is a panic attack. It is frightening but not dangerous. It will pass.”
- Breathe slowly — breathe in through the nose for 4 seconds, out through the mouth for 6. Slow exhale activates the calming nervous system.
- Ground yourself — notice 5 things you can see, 4 you can hear, 3 you can touch.
- Stay put if possible — leaving reinforces the belief that the situation is dangerous.
- Do not fight it — accepting the sensations reduces their intensity.
Panic attacks vs medical emergencies
Panic symptoms mimic heart attack and other serious conditions. Rules of thumb:
- First-ever severe chest pain, breathlessness, or collapse → call 999
- Recognised panic pattern in someone already assessed by a GP → use calming techniques, but seek help if symptoms are different from usual
- When in doubt, get checked — especially with chest pain, fainting, or symptoms during exercise
When attacks keep happening
See a GP if you have:
- recurrent panic attacks
- constant worry about having another attack
- avoidance of places or situations (shops, driving, leaving home)
- attacks affecting work, relationships, or quality of life
This pattern may be panic disorder — highly treatable.
Treatment
Cognitive behavioural therapy (CBT) — the most effective treatment. Helps you understand the cycle of panic, challenge catastrophic thoughts, and gradually face feared situations. Available through NHS talking therapies (self-referral in England via nhs.uk/talk).
Medication — SSRIs (such as sertraline) reduce attack frequency. Used alongside CBT or when therapy access is delayed. Benzodiazepines are avoided long-term due to dependence risk.
Self-help:
- reduce caffeine and alcohol
- regular sleep and exercise
- mindfulness and relaxation practice
- apps such as NHS-approved digital CBT tools
Panic attacks and agoraphobia
Repeated attacks can lead to agoraphobia — avoiding places where escape feels difficult or help unavailable. Early treatment of panic disorder prevents this pattern becoming entrenched.
Supporting someone having a panic attack
Stay calm, speak slowly, encourage slow breathing, and avoid telling them to “calm down” (which can feel dismissive). Reassure them it will pass. Help them sit somewhere safe until symptoms subside.
You are not alone
Panic disorder affects roughly 1 in 50 people at some point. Effective treatment exists — most people recover significantly with CBT. Asking for help is the first step, not a sign of weakness.
Common questions
- What does a panic attack feel like?
- Sudden intense fear or dread with racing heartbeat, chest tightness, breathlessness, dizziness, trembling, sweating, nausea, and feeling detached from reality or fear of dying. Symptoms peak quickly — usually within 10 minutes — then subside.
- Are panic attacks dangerous?
- Panic attacks themselves are not physically dangerous — you cannot die from a panic attack, though they feel terrifying. However, first-time severe chest pain or breathlessness should be assessed urgently to rule out heart or lung problems.
- What triggers panic attacks?
- Stress, caffeine, lack of sleep, certain situations (crowds, driving), and sometimes no obvious trigger. They are linked to anxiety and panic disorder but can occur in people without a general anxiety diagnosis.
- How can I calm a panic attack?
- Remind yourself it will pass and is not dangerous. Breathe slowly — in through the nose for 4 counts, out through the mouth for 6. Ground yourself — name 5 things you can see, 4 you can hear. Stay where you are rather than fleeing, which reinforces fear.
- How are recurring panic attacks treated?
- Cognitive behavioural therapy (CBT) — including exposure therapy — is the most effective treatment. SSRIs (antidepressants) help some people. Lifestyle changes — reducing caffeine, regular sleep, exercise — support recovery. NHS talking therapies are available via self-referral in England.
