The Fight-or-Flight Response Prepares Your Body to Take Action

The fight or flight response (also known as the acute stress response), refers to a physiological reaction that occurs when we are in the presence of something that is mentally or physically terrifying.

• The fight-or-flight response is triggered by the release of hormones that prepare your body to either stay and deal with a threat or to run away to safety.

The term "fight-or-flight" represents our ancient ancestors' choices when faced with danger in their environment.

• The physiological and psychological response to stress prepares the body to react to the danger.

In response to acute stress, the body's sympathetic nervous system is activated by the sudden release of hormones.

• After the threat is gone, it takes between 20 to 60 minutes for the body to return to its pre-arousal levels.

Physical signs that can indicate the fight-or-flight response has kicked in include:

• Dilated pupils: In times of danger, the body prepares itself to be aware of its surroundings
• Pale or flushed skin: Blood flow to the surface area is reduced
• Rapid heart rate and breathing: Provides the body with oxygen
• Trembling: The muscles tense and become primed for action
