A panic attack peaks within about 10 minutes and always passes - knowing that is the first tool. In the moment: slow your breathing (longer out than in), ground yourself with the 5-4-3-2-1 senses method, and let the wave crest rather than fighting it.
In the moment: breathe out slowly - inhale 4 counts, exhale 6 to 8 - because over-breathing (hyperventilation) drives the tingling, dizziness and chest tightness; extending the exhale directly calms the alarm system. Ground: name 5 things you see, 4 you can touch, 3 you hear, 2 you smell, 1 you taste - it forces your brain back to the present. Cold water on your face or holding ice triggers the dive reflex, which physiologically slows the heart. And the paradox that works: stop fighting it - say 'this is panic, it peaks and passes, it has every time' - resisting feeds it. What not to do: do not flee to your car and drive mid-attack (pull over first), and do not interpret the chest symptoms as catastrophe mid-wave - a first-ever attack with chest pain deserves one medical rule-out, but recurring known panic is the pattern you already know. Preventing the next one: cut caffeine and nicotine, fix sleep, exercise (genuinely reduces attack frequency), and learn CBT - the most effective long-term treatment, available through therapists and apps. Frequent attacks or avoidance behavior (skipping places for fear of one) is the point where treatment beats self-management: therapy works, and SSRIs are the first-line medication when needed - a telehealth visit can start that conversation for $50 to $100 cash. Emergencies skip this list: chest pain, trouble breathing, stroke signs, severe bleeding, or thoughts of self-harm mean call 911, or 988 for a mental health crisis in the US.
What to do
Common questions
How do I know it's a panic attack and not a heart attack?
Honestly, the first time, you often cannot - which is why a first episode of crushing chest pain, especially with pain radiating to the arm or jaw, sweating, or shortness of breath, deserves an emergency evaluation, full stop. The patterns that tilt panic once you have been cleared: attacks that peak within 10 minutes, tingling in hands and around the mouth, a sense of unreality or doom, and full resolution - especially in younger people without cardiac risk factors. Rule the heart out once; after that, you can trust the pattern.
Why does breathing out slowly help?
Panic makes you over-breathe, which blows off carbon dioxide - and low CO2 is what causes the tingling, lightheadedness, chest tightness and feeling of unreality. Slow, extended exhales let CO2 normalize and directly activate the parasympathetic (calming) nervous system via the vagus nerve. It is not a placebo - it is reversing the chemistry of the attack. Paper bags work the same way but the slow-exhale method is less conspicuous and just as effective.
Can panic attacks kill you or make you faint?
Neither, essentially - they feel lethal and are not. Fainting during panic is rare because panic raises blood pressure (fainting needs it to drop). They do not cause heart attacks in a healthy heart, and 'going crazy' during one does not happen - the unreality feeling is the CO2 effect plus adrenaline, and it passes with the attack. The real cost of panic is the avoidance it teaches: skipping highways, stores, flights. That shrinking is what treatment targets.
When do panic attacks need professional treatment?
When they are recurring, when you have started avoiding places or activities for fear of one (that is panic disorder taking shape), when they wake you from sleep regularly, or when the fear of attacks is running your week. The good news: panic is one of the most treatable conditions in mental health - CBT specifically for panic has high success rates in weeks to months, and SSRIs help when medication is warranted. Telehealth handles the evaluation and medication side well. Emergencies skip this list: chest pain, trouble breathing, stroke signs, severe bleeding, or thoughts of self-harm mean call 911, or 988 for a mental health crisis in the US.
