Panic
Panic refers to sudden surges of intense fear or discomfort that peak quickly and are accompanied by strong physical sensations.
In reference sources, panic is described as a rapid activation of the body’s threat-response systems rather than a gradual buildup of worry.

Sudden chest pain, fainting, or new neurological symptoms should be medically evaluated.
Key characteristics of panic
Panic is typically marked by rapid onset, high intensity, and a short time to peak.
The experience is often described as overwhelming and urgent, even when no external danger is present.
Physical sensations commonly dominate the experience, and thoughts often emerge afterward as interpretations of what the sensations might mean.
Common physical sensations
Reference descriptions of panic commonly include racing or pounding heart, chest tightness, shortness of breath, dizziness, shaking, sweating,
hot or cold sensations, nausea, and feelings of unreality or detachment.
Many people also report fear of dying, losing control, or passing out during a panic episode.
Why panic occurs
Panic reflects a rapid shift into fight-or-flight.
The nervous system reacts as if there is immediate threat, even in safe environments.
Sensations associated with this response can be misinterpreted as dangerous, which may intensify fear and sustain the episode.
Assessment and medical context
In clinical settings, panic is evaluated by examining symptom pattern, frequency, triggers, avoidance, and concern about future episodes.
Medical evaluation is sometimes used to rule out conditions that can produce similar physical symptoms.
