Signs of a Panic Attack: What They Are and What to Do

A panic attack arrives without obvious reason. You might be sitting at a desk, lying in bed, driving on a highway, or standing in a queue at a grocery store. Suddenly, the heart starts racing. The chest tightens. You feel you can't breathe properly. A wave of terror spreads through the body, and somewhere underneath it all, the thought: "Is this a heart attack? Am I dying?"

This is a panic attack. The body's emergency response system activating suddenly and dramatically in the absence of actual danger. Everything about the experience feels like a medical emergency. The good news is that panic attacks, while extremely unpleasant and frightening, are not physically dangerous. The bad news is that they're also hard to manage without understanding what's happening and why.

What a Panic Attack Actually Is

The fight-or-flight response is a survival mechanism: faced with a genuine threat, the nervous system floods the body with adrenaline, speeding the heart, tightening the chest, redirecting blood to muscles, sharpening alertness. This system saves lives.

A panic attack is this system activating in the absence of real danger. The physiological response is genuine — your body is doing exactly what it would do if you were running from a threat. But there's no threat. The experience is real; the danger isn't.

The mismatch between the intensity of the physical response and the actual safety of the situation is what makes panic attacks so terrifying, and why so many people who have their first one go directly to an emergency room convinced they're having a heart attack.

The Signs: What a Panic Attack Feels Like

Panic attacks typically peak within 10 minutes and resolve within 20–30 minutes, though they can feel much longer. Symptoms include:

Physical:

• Racing or pounding heart (palpitations)
• Chest pain or pressure — often feels like a heart attack
• Shortness of breath, feeling of not being able to breathe or breathe deeply enough
• Sweating
• Trembling or shaking
• Feeling of choking or a lump in the throat
• Dizziness, lightheadedness, or faintness
• Nausea or stomach discomfort
• Tingling or numbness in hands, feet, or face (from hyperventilation reducing carbon dioxide)
• Hot flashes or chills
• Dry mouth

Psychological:

• Intense fear or terror
• Derealization (the world feels unreal, dreamlike, or distant)
• Depersonalization (feeling detached from yourself)
• Fear of losing control or "going crazy"
• Fear of dying — often specifically fear of heart attack or suffocation

Not everyone has all these symptoms. Some people's panic attacks are primarily physical; others are predominantly psychological. Most are a combination.

How to Tell a Panic Attack from a Heart Attack

This is the most common concern during a first panic attack, and understandably so. Both cause chest pain, shortness of breath, and intense fear. Key differences:

1. Heart attack chest pain:

• Usually described as a heavy, crushing, or squeezing pressure
• Often radiates to the left arm, jaw, neck, or back
• May be brought on by exertion
• Builds gradually, or comes on suddenly with exertion
• Does not resolve quickly

2. Panic attack chest symptoms:

• Often sharp or tight
• Usually stays in the chest area
• Can happen completely at rest
• Peaks quickly (within 10 minutes)
• Resolves within 20–30 minutes

When genuinely uncertain — especially if you're older, have heart disease risk factors, or this is your first episode — getting evaluated medically is the right call. Most people who go to emergency rooms with panic attacks receive a normal ECG, normal blood tests, and a diagnosis of anxiety. That's not a bad outcome — knowing it's a panic attack, not a cardiac event, is genuinely useful information.

After a panic attack has been properly evaluated and a cardiac cause ruled out, subsequent episodes can be managed with more confidence.

What Triggers Panic Attacks

Sometimes they come completely out of nowhere. Other times, identifiable triggers include:

• Stress accumulation — often occurs when a stressful period ends, not just during it
• Caffeine, particularly in large amounts
• Alcohol withdrawal
• Sleep deprivation
• Entering a situation previously associated with panic (crowded places, elevators, driving)
• Hyperventilating (rapid breathing can trigger the physical symptoms)
• Certain medications
• Medical conditions (including thyroid problems, hypoglycaemia, cardiac arrhythmias)
• Cannabis use
• Hormonal changes (perimenopausal fluctuations, premenstrual phase)

For many people, panic attacks occur without an identifiable trigger — the nervous system seems to have developed a hair-trigger that fires unpredictably.

What to Do During a Panic Attack

The most important thing is to let the attack pass without fighting it. The instinct is to resist the panic, which actually amplifies it. Accepting that this is a panic attack, it will pass, and you are not in danger is the psychological foundation.

1. Controlled breathing

Panic attacks typically involve hyperventilation — rapid, shallow breathing that drops carbon dioxide in the blood, producing dizziness, tingling, and more fear. Slow breathing reverses this.

Box breathing: Breathe in for 4 counts, hold for 4, breathe out for 4, hold for 4. Repeat.

Physiological sigh: A double inhale through the nose followed by a long slow exhale through the mouth. Research suggests this resets the breathing pattern faster than other techniques.

The goal is to slow the breath and particularly to lengthen the exhale, which activates the parasympathetic nervous system.

2. Grounding techniques

When the mind is catastrophising, grounding it in the physical present helps break the loop.

5-4-3-2-1: Name 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, 1 you can taste. Each sense brings attention back to the present.

Cold water: Splashing cold water on the face or holding ice triggers the dive reflex, slowing the heart rate.

Physical grounding: Press your feet firmly into the floor. Notice the sensation. Feel the chair under you.

3. Don't flee

The instinct is to escape — run from the supermarket, pull off the road, leave the situation. This provides immediate relief but teaches the brain that the situation was genuinely dangerous. Over time, avoidance builds the panic disorder rather than reducing it.

If safe to do so, staying in the situation until the panic subsides is part of long-term recovery.

4. Remember: this will pass

Every panic attack ends. The peak is 10 minutes, and within 20–30 minutes the worst is over. Reminding yourself of this mid-attack — "this is a panic attack, it will pass, I am not in danger" — is more useful than it sounds.

Panic Disorder vs Occasional Panic Attacks

Many people have occasional panic attacks — isolated episodes without significant life disruption. This is common.

Panic disorder is when panic attacks are recurrent, unexpected, and the person develops:

• Persistent concern about having more attacks
• Worry about what the attacks mean (heart disease, mental illness)
• Significant behavioural changes to avoid situations associated with attacks (agoraphobia)

Panic disorder is a medical condition. It responds well to treatment — both psychological (CBT) and, when needed, medication.

When to See a Doctor

See a doctor:

• After any first episode of chest pain, breathlessness, or palpitations — to rule out cardiac causes
• If panic attacks are recurrent (more than two to three in a month)
• If you're avoiding situations or activities because of fear of panic attacks
• If panic attacks are significantly affecting work, relationships, or quality of life
• If you're feeling depressed alongside the anxiety
• If you've developed agoraphobia (avoiding public places, travel, or leaving home)

Treatment

Cognitive Behavioural Therapy (CBT): the most evidence-based treatment for panic disorder. Teaches identifying thought patterns that maintain panic, reframing catastrophic interpretations, and exposure (gradually facing feared situations). Twelve to twenty sessions typically produce significant, durable improvement.

Medication: SSRIs (commonly prescribed antidepressants that also treat anxiety) reduce panic attack frequency and intensity. Usually started at a low dose and titrated. Takes 2–4 weeks for full effect. Typically continued for at least a year after stabilisation.

Short-term medications (benzodiazepines like clonazepam): sometimes used for acute episodes or while waiting for SSRIs to work. Not a long-term solution — they're effective but carry dependence risk.

Lifestyle factors that reduce panic attack frequency: adequate sleep, regular exercise, limited caffeine, limited alcohol, stress management, consistent daily routine.

CBT combined with medication is typically more effective than either alone for significant panic disorder.

What Panic Attacks Don't Mean

They don't mean you're "going crazy." They don't mean you're weak. They don't mean something is medically seriously wrong with your heart or brain. They don't mean you'll have them forever. They don't mean you need to restructure your life around avoiding them.

Mental health conditions are medical conditions. Panic disorder has clear neurobiological underpinnings and responds to treatment. Getting evaluated and treated is the sensible response, in the same way that getting a broken bone set is the sensible response to breaking a bone.
