A panic attack typically lasts from 2 to 8 minutes and is one of the most distressing conditions that a person can experience in everyday life.
The various symptoms of a panic attack can be understood as follows. First comes the sudden onset of fear with little or no provoking stimulus. This then leads to a release of adrenaline (epinephrine) which cause the so-called fight-or-flight response where the person's body prepares for major physical activity. This leads to an increased heart rate (tachycardia), rapid breathing (hyperventilation), and sweating (which increases grip and aids heat loss). Because strenuous activity rarely ensues, the hyperventilation leads to carbon dioxide levels lowering in the lungs and then the blood. This leads to shifts in blood pH which can in turn lead to many other symptoms, such as tingling or numbness, dizziness, and lightheadedness. (It is also possible for the person experiencing such an attack to feel as though they are unable to catch their breath, and they begin to take deeper breaths. This also acts to decrease carbon dioxide levels in the blood.)
Anyone who hyperventilates for a while can demonstrate these symptoms. For the person with a panic attack who does not know this, these symptoms are often seen as further evidence of how serious the condition is. An ensuing vicious cycle of adrenaline release fuels worsening physical symptoms and psychological distress.
