The
fight-or-flight response (among other names) is a physiological reaction that occurs in response to a perceived
harmful event,
attack, or threat to survival. Animals react to threats with a general discharge of the
sympathetic nervous system, preparing the animal for fighting or fleeing. The
adrenal medulla produces a hormonal cascade that results in the secretion of
catecholamines, especially
norepinephrine and
epinephrine. The hormones
estrogen,
testosterone, and
cortisol, as well as the neurotransmitters
dopamine and
serotonin, also affect how organisms react to stress. The hormone
osteocalcin might also play a part.

organisms involves the fight-or-flight response as it first stage. A
panic attack is a sudden period of intense
fear and discomfort that may include
palpitations, sweating,
chest pain, shaking,
shortness of breath,
numbness, or a feeling of impending doom or of losing control. Typically, symptoms reach a peak within ten minutes of onset, and last for roughly 30 minutes, but the duration can vary from seconds to hours. Though distressing, panic attacks themselves are not physically dangerous. They can either be triggered or occur unexpectedly. In psychology, there is an identified condition called
panic disorder that has been described as a specific psychological vulnerability of people to interpret normal physical sensations in a catastrophic way. It is related strongly to biological and psychological factors and their interactions. Leonard J. Schmidt and Brooke Warner describe panic as "that terrible, profound emotion that stretches us beyond our ability to imagine any experience more horrible" adding that "physicians like to compare painful clinical conditions on some imagined 'Richter scale' of vicious, mean hurt … to the psychiatrist there is no more vicious, mean hurt than an exploding and personally disintegrating panic attack." on the Seamen's Savings' Bank during the
Panic of 1857 Panic attacks can occur due to several other disorders including
social anxiety disorder,
post-traumatic stress disorder,
substance use disorder,
depression, and medical problems. Panic in social psychology is considered infectious since it can spread to a multitude of people and those affected are expected to act irrationally as a consequence. Psychologists identify different types of this panic event with slightly varying descriptions, which include
mass panic, mass hysteria,
mass psychosis, and
social contagion. An influential theoretical treatment of panic is found in
Neil J. Smelser's
Theory of Collective Behavior. The science of panic management has found important practical applications in the armed forces and emergency services of the world. == Effects ==
