The fight or flight response, also known as acute stress response, is a physiological reaction that occurs in response to a perceived harmful event or threat to survival. It is an instinctive response deeply ingrained in the human nervous system, triggered by the release of stress hormones such as adrenaline and cortisol.
When an individual perceives danger, the brain's amygdala activates the hypothalamus and triggers a series of immediate physiological changes. These changes include increased heart rate, elevated blood pressure, rapid breathing, and boosted energy levels. These bodily reactions enable the body to prepare for either confrontation (fight) or escape (flight) from the threatening situation.
In the fight response, the individual may exhibit heightened aggression, tense muscles, and increased focus, ready to confront the source of danger head-on. On the other hand, in the flight response, the individual tends to resort to avoidance or escape strategies, manifested through increased alertness, anxiety, and the urge to retreat from the perceived threat.
The fight or flight response is an evolutionary adaptive mechanism, allowing individuals to quickly respond to danger, increasing their chances of survival. While this response is crucial in life-threatening situations, it can also be activated in non-life-threatening scenarios, such as public speaking or exams, leading to heightened anxiety and stress.
Understanding the fight or flight response can help individuals recognize and manage their stress reactions, allowing them to respond in a more controlled and rational manner, which can be beneficial for overall well-being and decision-making abilities.
