Panic attack symptoms
If this is happening to you right now: it will pass. Panic attacks feel terrifying but are not dangerous. Here is exactly what is happening in your body — and what to do.
Quick answer
Panic attack symptoms:
- Racing or pounding heart (palpitations)
- Shortness of breath or feeling of suffocation
- Chest tightness or chest pain
- Dizziness or lightheadedness
- Tingling or numbness in hands, arms, or face
- Sweating, chills, or hot flashes
- Shaking or trembling
- Nausea or stomach discomfort
- Feeling detached from reality (derealization)
- Intense fear that something terrible is about to happen
DSM-5 diagnostic criteria for panic attack — American Psychiatric Association
Your heart is pounding. You can't breathe properly. You feel like something terrible is about to happen.
These are classic panic attack symptoms — not signs of a heart attack or a breakdown. Your amygdala has triggered the fight-or-flight response without an actual physical threat. It feels catastrophic, but it is temporary. Every panic attack peaks and passes.

Why panic attack symptoms feel so physical
Every symptom of a panic attack has a direct physiological cause. The amygdala — your brain's threat detector — triggers a massive adrenaline release. That adrenaline does exactly what it's supposed to do: it prepares your body for a physical emergency. The problem is, there is no emergency.
Your heart races because adrenaline increases cardiac output to pump blood to your muscles. You feel breathless because your breathing quickens to take in more oxygen. Tingling in your hands happens because blood is redirected away from your extremities to your large muscle groups. Derealization occurs because the brain's threat-processing mode suppresses non-essential higher cognition.
None of these symptoms are dangerous on their own. They are unpleasant and frightening — but they are the natural output of a healthy stress response system firing without cause.
Racing heart
Adrenaline increases cardiac output. Not dangerous — your heart is designed to handle it.
Breathlessness
Rapid breathing increases oxygen — but too much O₂ can cause tingling and dizziness.
Derealization
The brain's threat mode suppresses higher cognition — creates "unreal" feeling. Always temporary.
If you experience chest pain that does not improve, pain radiating to the arm or jaw, or you are unsure whether it's a panic attack — call 911 or local emergency services immediately.
What to do during a panic attack — in order
Don't fight it — label it
10 secFighting the symptoms makes them worse. Instead, say out loud: "This is a panic attack. It will pass. I am not in danger." Affect labeling (naming the emotion) reduces amygdala activity measurably within seconds. Acceptance — not resistance — is the fastest path through.
Extended exhale breathing
60 secBreathe in slowly for 4 counts. Breathe out for 6–8 counts. The long exhale activates the vagus nerve and begins to counteract the adrenaline surge. Do not breathe into a bag — this is outdated advice. Controlled slow exhalation is the evidence-based intervention.
Guided breathing toolGround your senses
90 secName 5 things you can see right now. Touch something and notice its texture. This breaks the catastrophic thought loop by forcing your brain into present-moment sensory processing. The panic attack cannot escalate when your brain is occupied with immediate sensory input.
Wait it out
10 minThe peak of a panic attack lasts under 10 minutes. If you are breathing slowly and have labelled the experience, it will subside. After the attack passes, drink water, sit quietly for a few minutes, and avoid immediately going back to a stressful situation.
