Panic attacks are intense episodes of sudden fear or anxiety that can trigger severe physical and emotional symptoms. These symptoms can include rapid heartbeat, shortness of breath, chest pain, trembling, dizziness, and a feeling of impending doom. Panic attacks can be overwhelming and distressing, often leading to a strong desire to escape the situation. They typically peak within a few minutes and gradually subside, but their effects can linger. While panic attacks are intense, they are not life-threatening. However, they can significantly impact daily life and well-being.
