Quick answer: A panic attack is a sudden episode of intense fear or discomfort that peaks within minutes, usually lasting 5 to 20 minutes. It includes at least four physical or cognitive symptoms (racing heart, shortness of breath, chest pain, fear of dying or losing control) even though there is no real danger. Panic attacks are treatable and not life-threatening, though the experience feels frightening.
If you are in the middle of a panic attack right now, call 988 (US), NHS 111 option 2 (UK), or emergency services. The rest of this article explains what is happening in your body.
What is a panic attack?
According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the standard diagnostic reference used by clinicians worldwide, a panic attack is "an abrupt surge of intense fear or intense discomfort that reaches a peak within minutes." The DSM-5 lists 13 possible symptoms. You need at least four for it to count as a panic attack: palpitations or accelerated heart rate, sweating, trembling or shaking, shortness of breath, choking sensation, chest pain or discomfort, nausea or abdominal distress, dizziness or lightheadedness, feelings of unreality or detachment, fear of losing control or going crazy, fear of dying, paresthesias (tingling sensations), and chills or hot flushes.
The key point: there is no real threat. Your amygdala (your brain's alarm center) fires as if there is a grizzly bear in front of you, but there is none. That is why the terror feels overwhelming but is not dangerous.
A single panic attack does not mean you have a panic disorder. Many people have one or two in their lifetime, usually during periods of major stress. If they become frequent and unexpected, and you start avoiding situations out of fear of another attack, that pattern is panic disorder, which is different.
Panic attack vs. anxiety attack: what is the difference?
People often use "panic attack" and "anxiety attack" interchangeably, but they are not the same. Panic attacks come on suddenly, peak within 5 to 10 minutes, and include at least 4 DSM-5 symptoms. Anxiety is a gradual sense of worry or dread, often tied to a real or imagined future threat. It builds slowly and can last hours or days.
A panic attack is like a fire alarm blaring suddenly. Anxiety is like a slow rise in background worry.
Physical and mental symptoms
Panic attack symptoms occur suddenly and peak within about 10 minutes:
Physical symptoms:
- Racing heart or palpitations
- Shortness of breath or hyperventilation
- Chest pain or tightness
- Trembling or shaking
- Sweating
- Dizziness or lightheadedness
- Numbness or tingling in hands and feet
- Nausea or stomach pain
- Chills or hot flushes
Cognitive and emotional symptoms:
- Fear of dying
- Fear of losing control or going crazy
- Sense of impending doom
- Feeling detached from your body or surroundings (depersonalization)
- Difficulty concentrating
These symptoms are real. Your nervous system genuinely is in fight-or-flight mode. The symptoms are caused by a flood of stress hormones (adrenaline, cortisol), not by a physical threat.
What triggers a panic attack?
Panic attacks can be triggered by:
- Identifiable stressors: major life changes, work pressure, illness, grief, caffeine, alcohol withdrawal
- Specific situations: crowded places, flying, driving, being alone
- Physical sensations: noticing your heart racing (then fearing it is a heart attack, which triggers more adrenaline)
- Spontaneous: many come "out of the blue" with no clear trigger
Genetic factors also play a role. Panic disorder runs in families, and certain temperaments (anxious, sensitive to body sensations) are at higher risk.
How long does a panic attack last?
Most panic attacks peak within 10 minutes and subside within 5 to 20 minutes total. Lingering symptoms (exhaustion, residual anxiety, shakiness) can last 30 minutes to a few hours. If an attack lasts longer than 30 to 60 minutes without easing, seek medical attention to rule out other causes.
Is a panic attack dangerous?
No. A panic attack cannot directly kill you. It is an intense but temporary activation of your fight-or-flight system. Your heart will not stop, you will not stop breathing, and fainting during panic is extremely rare (blood pressure actually rises, not falls).
That said, if chest pain or shortness of breath is new, severe, or you have heart disease risk factors, have it checked by a clinician to be safe.
When to worry and seek help
See a doctor or therapist if:
- You have had 2 or more unexpected panic attacks and now fear the next one
- You are avoiding places, people, or situations because of panic
- Panic is interfering with work, school, or relationships
- You have new or unexplained chest pain
- You have thoughts of harming yourself
Cognitive behavioral therapy (CBT) is the first-line, evidence-based treatment for panic disorder and works in about 80% of cases. Medication (SSRIs) may be added when panic is frequent.
FAQ
What exactly happens in the body during a panic attack?
Your amygdala detects a threat signal (real or perceived) and activates the sympathetic nervous system, flooding your body with adrenaline and cortisol. Your heart rate and breathing accelerate, blood sugar rises, blood is diverted to muscles, and your digestive system slows. These are survival responses designed for actual danger. In panic, the alarm fires when there is no danger, but the body does not know that.
Can you have a panic attack without anxiety?
Yes. Many people experience unexpected panic attacks that seem to come out of nowhere, with no preceding anxiety or stressor. Others notice them during sleep (nocturnal panic attacks). In both cases, the physical surge happens first, and fear of it follows.
How is a panic attack different from a heart attack?
Both can cause chest pain, rapid heart rate, and shortness of breath. Key differences: panic peaks within 5 to 10 minutes and has emotional/cognitive symptoms (fear, sense of doom), while a heart attack is caused by a blocked blood vessel, may develop more gradually, and shows specific changes on an EKG. When in doubt, get it checked.
Can panic attacks be cured?
Panic attacks themselves are treatable with CBT, which teaches your brain not to interpret the physical sensations as dangerous. With the right therapy or medication, 70 to 90% of people see significant improvement or full recovery. Panic disorder is manageable, but ongoing stress management and self-awareness are important.
