Broadly speaking, the immune system's fight-or-flight response is a cornerstone of stress research. 3. Nervous energy builds up in the brain to cope with or avoid a stressful situation, and so is this excess mental energy. The human stress response is a complementary homeostatic mechanism that provides a better chance of survival when the body is threatened and mobilizes neural and hormonal networks to optimize. Introduction. Dealing with stress takes energy. In an acute stress situation, metabolic resources are mobilized to meet the increased energy demand for “fight or flight” Berthoud, 2002. Blood sugar levels are elevated, lipids are mobilized from fat stores, body temperature, heart rate, blood pressure and respiration are increased to overcome , fight or flight in everyday life. The fight-or-flight response is a crucial survival mechanism. In non-human animals, instinct, experience and circumstances determine whether an animal will run away. “The fight-or-flight response, or stress response, is caused by the release of hormones that prompt us to stay and fight or run and flee,” explains psychologist Carolyn Fisher, PhD.

In these individuals, symptoms either occur far too often or at inappropriate times. There may be several reasons for this: Fight-or-flight response, response to an acute survival threat characterized by physical changes, including nervous and endocrine changes, that prepare a human or animal to respond or retreat. The functions of this reaction were first described in the 1990s by the American,
