The fight-or-flight or the fight-flight-freeze-or-fawn [1] (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. [2] It was first described by Walter Bradford Cannon in 1915.
If the amygdala perceives a match to the stimulus, i.e., if the record of experiences in the hippocampus tells the amygdala that it is a fight, flight or freeze situation, then the amygdala triggers the HPA (hypothalamic–pituitary–adrenal) axis and "hijacks" or overtakes rational brain function. [5]
The reaction occurs in certain situations and is at the opposite end of the spectrum as fight or flight. ... 13 Signs You’re Experiencing a Freeze Stress Response.
The body's response to stress is also termed a "fight or flight" response, and it is characterised by an increase in blood flow to the skeletal muscles, heart, and brain, a rise in heart rate and blood pressure, dilation of pupils, and an increase in the amount of glucose released by the liver. [8]
You’ve heard of fight or flight—but wait, there’s more! ... Freeze response can occur especially in moments of feeling trapped, but Chang says the response is simply your body trying to save ...
A common misunderstanding can be that FFS is a measure of one's reaction to lean more towards fighting or to lean more towards fleeing in response to perceived threats; [20] however, FFS is a measure of one's intensity to respond with either fight or flight behavior, as opposed to reacting not so acutely to perceived threats. [20]
The fight-or-flight response involves a general sympathetic nervous system discharge in reaction to a perceived stressor and prepares the body to fight or run from the threat causing the stress. Catecholamine hormones, such as adrenaline or noradrenaline , facilitate immediate physical reactions associated with a preparation for violent ...
Many researchers believe that these results underlie the reasons why men administer a fight-or-flight reaction to stress; whereas, females have a tend-and-befriend reaction. [65] The "fight-or-flight" response activates the sympathetic nervous system in the form of increased focus levels, adrenaline, and epinephrine. Conversely, the "tend-and ...
