What Happens When You Have a Panic Attack
It's More Than Being Scared
Having a panic attack. Your body's "fight or flight" response kicks into high gear. It can seem to come from nowhere -- maybe as you walk down the street or do the laundry. It can even wake you out of a sound sleep. There's often no obvious reason for your combination of symptoms. That's part of why it's called an "attack." It can be so sudden and intense that you feel helpless, unable to move or think clearly.
A jolt of adrenaline gets your heart racing or pounding -- or both. Your chest might hurt. You could even have trouble breathing.
Your throat tightens up, and you can't swallow. Or you might think you're going to throw up. These feelings can make it harder to catch your breath.
We're not talking about the fear you feel in the normal course of life, when you stand on the edge of a cliff, bring up a difficult subject, or start a new job, for example. During a panic attack, you may have an overwhelming sense that something really terrible is about to happen -- or that you're going to die -- despite knowing it's not true.
