A panic attack is a sudden surge of fear and physical activation that usually reaches its highest intensity within a few minutes. Although the sensations may feel dangerous, the aim during an episode is not to force yourself to calm down. It is to check that you are safe, reduce over-breathing, reconnect with the present and allow the wave to fall without feeding it through repeated checking, immediate escape or a constant struggle against every sensation.
Panic attack symptoms and what to do during an episode raise many questions because the experience can resemble a medical emergency. The heart races, breathing feels difficult, dizziness or chest tightness may appear, and there can be an overwhelming sense that something terrible is about to happen.
At that moment, phrases such as “calm down” or “just stop thinking about it” are rarely helpful. The person is not exaggerating. Their alarm system has activated with enormous intensity, even though there may be no equivalent external danger.
This guide explains how to recognise a panic attack, how long it commonly lasts, which techniques may help in the moment, which responses tend to maintain the problem and when to seek medical or psychological assessment. It does not replace healthcare evaluation, particularly when symptoms are new, different from previous episodes or not clearly attributable to anxiety.
What is a panic attack?
A panic attack is a sudden onset of intense fear or discomfort accompanied by physical and cognitive symptoms. It may arise in a feared situation — for example, driving, entering a shopping centre or speaking in public — but it can also occur unexpectedly, including while a person is resting or asleep.
A single panic attack does not necessarily mean that someone has a psychological disorder. Some people experience one during a period of severe stress, exhaustion, illness, heavy stimulant use or major life change. Panic disorder involves recurrent unexpected attacks together with at least a month of persistent concern about further episodes or significant behavioural changes intended to prevent them.
Panic attack
A specific episode. It may happen once or occasionally and is not, by itself, a diagnosis.
Panic disorder
Involves recurrent unexpected attacks, persistent fear that they will happen again and changes such as avoiding places, exercise, travel or being alone.
Symptoms of a panic attack
Symptoms vary between people and may also differ from one episode to another. A person does not need to experience every symptom. What is characteristic is the combination of intense activation, the speed at which it rises and the interpretation that the sensations signal serious danger.
Heart and chest
Palpitations, a racing or pounding heartbeat, pressure, discomfort or tightness in the chest.
Breathing
Breathlessness, rapid breathing, a choking sensation, or tightness in the throat.
Balance and perception
Dizziness, unsteadiness, altered vision, feeling faint, detached from yourself or disconnected from the surroundings.
Temperature and skin
Sweating, chills, hot flushes, tingling or numbness in the hands, face or other areas.
Stomach and muscular tension
Nausea, abdominal discomfort, trembling, muscle tension, weak legs or a feeling of being physically frozen.
Alarm thoughts
Fear of dying, losing control, fainting, “going mad”, being embarrassed or being unable to obtain help.
How long does a panic attack last?
The most intense part usually builds quickly and reaches a peak within a few minutes. Many panic attacks settle within approximately 5 to 20 minutes, although some may last longer.
This does not mean that someone will feel completely recovered after twenty minutes. Tiredness, trembling, muscle discomfort, hypervigilance, fear that the attack will restart or a sense of unreality may remain afterwards. Sometimes it feels as though the episode lasted for hours when several waves of activation and bodily monitoring occurred one after another.
If the intensity does not reduce, symptoms are unusual, remain continuously severe for a prolonged period or there is any uncertainty about their cause, seek medical advice.
Why does a panic attack feel so dangerous?
The body activates processes that would normally help us respond to a threat: the heart rate increases, breathing changes, muscles tense and attention narrows towards possible danger. The problem is not only the initial activation, but the meaning we give to it.
For example, a palpitation may be interpreted as “I am having a heart attack”. Fear increases, the heart beats faster and the new acceleration appears to confirm the original belief. A self-reinforcing cycle develops.
“My heart is pounding”
“Something serious is happening”
Hyperventilation can also contribute. Breathing too quickly or too deeply lowers carbon dioxide levels and may increase dizziness, tingling, feelings of unreality and breathlessness. For this reason, repeatedly taking very large breaths during an episode is not usually helpful. A gentler, steadier breathing pattern is often more useful.
What to do during a panic attack: a step-by-step protocol
No technique switches off every panic attack immediately. A realistic aim is to reduce the responses that amplify the episode and help the nervous system complete its activation curve safely.
Check safety first
Stop in a safe place. If you are driving, pull over as soon as it is safe to do so. Seek medical attention if there are warning signs, new symptoms or reasonable uncertainty. Do not try to prove to yourself that it is “only anxiety” when you do not know that.
Give the experience a provisional name
If you have already been assessed and recognise the pattern, try saying: “My alarm system has activated. This feels extremely intense, but I know it rises and then falls.” Naming the experience can reduce some of the uncertainty.
Stabilise your posture
Place both feet on the floor, soften your shoulders and jaw, and let your hands rest. You do not need a perfect posture. Find a stable position that helps you notice the floor and chair supporting your body.
Make your breathing slower, not bigger
Rather than forcing the lungs to fill, let the in-breath remain gentle and allow the out-breath to last slightly longer. The aim is to reduce over-breathing, not to control every breath or repeatedly check whether the exercise is “working”.
Orient your attention outwards
Look around and describe concrete details: colours, shapes, sounds, temperature and points of physical contact. This does not remove fear instantly, but it reduces exclusive monitoring of internal sensations.
Allow the wave to come down
If you are in a safe situation, try not to escape automatically. You may stay for a few minutes, ask someone to remain with you and allow the peak to reduce. The learning is that the sensation can end without immediate escape or repeated reassurance and checking.
Psychological exercises for managing the episode
These tools are supportive strategies. They do not replace treatment when attacks are frequent, avoidance is developing or fear is restricting daily life. They should never be used to dismiss unexplained medical symptoms.
Exercise 1: gentle breathing with a slightly longer out-breath
Useful when you notice rapid breathing or that you are repeatedly taking in too much air.
- Place your feet on the floor and let the air leave without forcing it.
- Breathe in gently through your nose for around 3 seconds.
- Breathe out calmly for around 4 or 5 seconds.
- Repeat for 6 to 10 cycles without trying to fill the lungs completely.
- Then allow your breathing to return to its natural rhythm.
Important: if the exercise increases dizziness or makes you monitor breathing more closely, stop and direct your attention towards the environment. Breathing is one possible aid, not a test that you have to pass.
Exercise 2: 5–4–3–2–1 sensory orientation
A way to reconnect with the present when attention has become trapped inside the body.
- Name 5 things you can see.
- Notice 4 points of physical contact: your feet, back, clothing or temperature.
- Identify 3 sounds.
- Notice 2 smells or two neutral features of the environment.
- Observe 1 taste or one neutral sensation in your mouth.
Move through the exercise with curiosity rather than racing to complete it. You do not have to stop feeling anxious for it to be useful. Its purpose is to widen your attentional focus.
Exercise 3: a brief response to catastrophic thoughts
This is not about repeating positive statements. It is about responding with information that is more balanced and testable.
“I am going to faint”
“I feel dizzy and frightened. I will sit down, look at a stable point and observe what happens without predicting the outcome.”
“I am going to lose control”
“Feeling out of control does not mean that I will behave without control. I can take one simple action at a time.”
“This will never end”
“The body cannot remain at peak activation indefinitely. I can allow a few minutes to pass without fighting every sensation.”
“I have to leave now”
“First I will check whether I am safe. If I am, I can wait briefly before deciding whether I need to leave.”
What is best avoided during a panic attack?
May be helpful
- Use short, concrete sentences when speaking to yourself.
- Slow rapid breathing without forcing large inhalations.
- Place your feet on the floor and describe the environment.
- If you are safe, wait a few minutes before escaping.
- Ask for calm company without requiring another person to guarantee that nothing is wrong.
Often maintains the fear
- Checking your pulse or blood pressure repeatedly.
- Searching symptoms compulsively online.
- Repeatedly taking very deep, fast breaths.
- Using alcohol, cannabis or non-prescribed medication to stop the attack.
- Automatically leaving every place in which anxiety appears.
Safety behaviours may bring immediate relief, but in the longer term they can teach the brain that the situation really was dangerous and that catastrophe was prevented only because you escaped, checked your body or carried a particular safety object. Therapy aims to reduce these behaviours gradually and sensibly.
What to do after a panic attack
It is common to feel exhausted, shaken or embarrassed afterwards. You do not need to analyse everything immediately. First return to basic care: drink water if needed, eat normally, rest briefly and avoid punishing yourself for what happened.
When you feel more settled, a short record of the episode can be useful, provided that recording does not become an obsessive search for certainty or causes.
Complete these four sections when you are calm
Keeping a simple plan on your phone can be more helpful than trying to remember a long list of instructions at the height of anxiety.
A useful brief record
- Situation: where you were and what was happening beforehand.
- First sensation: what you noticed in your body.
- Interpretation: what you feared the sensation meant.
- Response: what you did to protect yourself.
- Actual outcome: what eventually happened and how long the intensity took to reduce.
The final point matters. The brain readily remembers fear, yet it may fail to register that the predicted catastrophe did not occur. Reviewing the actual outcome helps build a less threatening explanation of the experience.
Fear of another attack: anticipatory anxiety and avoidance
After a panic attack, many people begin monitoring the body: “Is my heart beating too quickly?”, “Am I breathing properly?”, “What if I become dizzy here?”. They may also avoid exercise, caffeine, public transport, supermarkets, driving, being alone or going far from a hospital.
Avoidance reduces anxiety in the short term, but it narrows life and maintains the belief that those situations are dangerous. A central part of treatment is therefore to recover activities gradually, using agreed steps and without turning exposure into a test of willpower.
Interoceptive exposure: working with fear of bodily sensations
Interoceptive exposure is a cognitive behavioural therapy technique. It involves deliberately and briefly bringing on certain harmless bodily sensations in a controlled way — for example, noticing a faster heartbeat after appropriately adapted physical activity — so that the person can develop a different interpretation and reduce fear of those sensations.
It is not a technique for use during an emergency and it is not a generic list of exercises suitable for everyone. It must be adapted to physical health, medical history, the symptoms involved and the person’s specific fears.
Do not begin interoceptive exposure exercises on your own if you have a heart, respiratory, neurological or vestibular condition, are pregnant, have a history of fainting, have a physical injury, have recently used substances, have unexplained symptoms or have any medical uncertainty. These situations require prior assessment and an individualised professional plan.
How to help someone who is having a panic attack
The person may interpret your own nervousness as further evidence that something dangerous is happening. You do not need to act as a therapist. Calm presence, clear communication and practical support are enough.
Keep your voice slow and steady
Use short sentences. Avoid surrounding the person with a crowd, arguing about whether the reaction is “reasonable” or asking many rapid questions one after another.
Ask what they need
“Has this happened before?”, “Is there anything that usually helps?”, “Would you like me to stay with you?”. Not everyone wants to be touched.
Help check for warning signs
If this is the first episode, there is new chest pain, fainting, severe breathing difficulty or unusual symptoms, seek medical help. Do not diagnose a panic attack yourself.
Stay without making promises
Instead of saying “nothing is wrong”, try: “I am here”, “we can wait together”, or “we can ask for medical help if anything changes”.
Psychological treatment for panic attacks
When attacks recur, anticipatory fear develops or life becomes organised around preventing another episode, therapy can help break the cycle. Cognitive behavioural therapy is one of the most strongly supported psychological approaches for panic disorder.
Assessment and psychoeducation
Therapy examines how attacks begin, which sensations appear, what they are believed to mean, which situations are avoided and which safety behaviours keep the cycle going.
Reviewing catastrophic interpretations
The person works on the tendency to interpret palpitations, dizziness or breathlessness as signs of death, fainting, loss of control or humiliation.
Interoceptive and situational exposure
Graded experiences with feared sensations and situations are used to develop new learning, reduce avoidance and lessen reliance on safety behaviours.
Breathing and regulation as supportive skills
When hyperventilation is involved, a steadier breathing pattern may be practised. However, breathing must not become a condition that the person believes is essential for safety.
Relapse prevention
A plan is developed for interpreting future sensations, responding to smaller increases in anxiety and maintaining the activities that have been regained.
In some cases, a doctor may consider medication. Decisions about prescribing, selecting, adjusting or withdrawing medication belong to qualified medical professionals. Do not start, increase, reduce or stop medication on your own.
When to seek professional help
A psychological assessment may be appropriate even when panic attacks do not happen every day. Consider seeking help when:
- attacks recur or appear to come unexpectedly;
- you spend a great deal of time worrying about the next episode;
- you avoid driving, going out, travelling, exercising or being alone;
- you feel unable to go anywhere without medication, water, a telephone or another person as a condition of safety;
- you have attended emergency services repeatedly and investigations have not explained the episodes;
- anxiety is affecting work, study, relationships or sleep;
- you use alcohol, cannabis or other substances to prevent or stop episodes;
- depression, hopelessness, self-harm or suicidal thoughts are also present.

Frequently asked questions about panic attacks
Can a panic attack kill me?
A panic attack itself is not usually life-threatening. However, its symptoms can resemble important medical problems. Seek healthcare assessment if this is the first episode, there is new chest pain, severe breathing difficulty, fainting or uncertainty about the cause.
How long does a panic attack take to pass?
Intensity usually reaches its highest point within a few minutes, and many attacks last approximately 5 to 20 minutes. Tiredness, fear and hypervigilance may continue afterwards.
How can I stop a panic attack quickly?
It is not always possible to stop one immediately. It may help to check safety, reduce rapid breathing, place both feet on the floor, orient attention towards the environment and allow the wave to fall without adding repeated checking or automatic escape.
Should I take deep breaths during a panic attack?
Not necessarily. Repeatedly breathing in very deeply and quickly may worsen hyperventilation. A gentle, regular and slightly slower breathing pattern is usually preferable to trying to fill the lungs completely.
Can a panic attack happen while I am asleep?
Yes. Some people wake with palpitations, intense fear and difficulty breathing. Other medical or sleep-related problems can cause similar symptoms, so seek advice if this happens for the first time or recurs.
How can I tell a panic attack from a heart attack?
It is not always possible to distinguish them without medical assessment. New or unexplained chest pain or pressure, radiating pain, cold sweating, fainting, marked breathing difficulty or cardiovascular risk factors require urgent medical help.
Can coffee trigger panic attacks?
Caffeine can increase palpitations, trembling and physical activation. Some sensitive people may interpret these sensations as dangerous. It can be useful to observe the relationship without assuming that caffeine is the only cause of the problem.
Can panic attacks be treated successfully?
Many people improve substantially with psychological treatment. Cognitive behavioural therapy can help change interpretations of bodily sensations, reduce avoidance and restore activities. Progress varies according to the individual and any coexisting difficulties.
