What causes panic attacks?
Panic attacks are sudden episodes of intense fear or anxiety. They often happen without warning and can cause physical symptoms like a racing heart, shortness of breath, dizziness, trembling, and sweating. During a panic attack, you might feel detached from reality, fear losing control, or worry about having a heart attack or dying.
