Flight or fight response

When someone confronts an oncoming car or other danger, the eyes or ears or both send the information to the amygdala, an area of the brain that contributes to emotional processing. Some animals stand perfectly still so that predators will not see them. This combination of reactions to stress is also known as the "fight-or-flight" response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life-threatening situations.

When we are faced with modern day, saber tooth tigers, we have to sit in our office and "control ourselves. Two excellent examples of stress induced conditions are "eye twitching" and "teeth-grinding. There may be a period of heightened awareness, during which each animal interprets behavioral signals from the other.

The quiet mind opens up our perceptions and frees us to make the most positive choices regarding our lives. Emotional mindfulness might sound like: This surge is the force responsible for mothers lifting cars off their trapped children and for firemen heroically running into blazing houses to save endangered victims.

How Cells Communicate During Fight or Flight

Once you determine the fears, find out if you are jumping to conclusions. An example of this is kittens playing: Are there other ways to quiet the mind.

The Flight Response The purpose of the flight response is to keep humans safe when a scary situation faces them. Try it as an experiment and see what happens. For example, researchers at Massachusetts General Hospital conducted a double-blind, randomized controlled trial of patients with hypertension, ages 55 and older, in which half were assigned to relaxation response training and the other half to a control group that received information about blood pressure control.

The person undergoing these changes also starts to breathe more rapidly. Start with simple stress managing steps. Many of these techniques are discussed in depth in Section 3 and they include: After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands.

When our fight or flight response is activated, sequences of nerve cell firing occur and chemicals like adrenaline, noradrenaline and cortisol are released into our bloodstream. The simplest, most exquisite way I know of to quiet the mind is by eliciting what is called "The Relaxation Response.

Over the years, researchers have learned not only how and why these reactions occur, but have also gained insight into the long-term effects chronic stress has on physical and psychological health. The relaxation response, discovered by the inspirational author and Harvard cardiologist, Herbert Benson, M.

It might not be possible to issue a mental directive to our adrenal glands to tell them to stop producing adrenalin and noradrenalin. Any form of phobia may trigger the fight or flight response. Is there a cumulative danger from over-activation of our fight or flight response.

People can suffer from decreased immunity as well as other health problems. This fundamental physiologic response forms the foundation of modern day stress medicine. The "fight or flight response" is our body's primitive, automatic, inborn response that prepares the body to "fight" or "flee" from perceived attack, harm or threat to our survival.

It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers. The parasympathetic nervous system acts like a brake.

It promotes the "rest and digest" response that calms the body down after the danger has passed. All of these changes are part of the fight or flight response.

As the name implies, these changes are preparing you for immediate action.

Understanding the stress response

They are preparing you to flee, freeze (kind of like a deer does when caught in someone's headlights), or to fight. The fight or flight response is a catch-all phrase describing the body's response to stress.

Fight or flight refers to the two choices our ancestors had when facing a dangerous animal or enemy. In that moment of stress (fear) the body prepares itself to be injured and to expend energy in the large muscle groups of the arms, legs and shoulders. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.

The parasympathetic nervous system acts like a brake. It promotes the "rest and digest" response that calms the body down after the danger has passed. To produce the fight-or-flight response, the hypothalamus activates two systems: the sympathetic nervous system and the adrenal-cortical system.

The sympathetic nervous system uses nerve pathways to initiate reactions in the body, and the adrenal-cortical system uses the bloodstream.
