The Fight or Flight Response

The "fight or flight" (stress) response stimulates your body and prepares it to deal with danger.  The response increases some of your body's processes including:

  • heart rate
  • breathing rate
  • muscle tension
  • blood pressure
  • insulin secretion
  • blood flow to the brain, lungs, heart and muscles
  • blood clotting

The "fight or flight" response also decreases some of your body's processes including:

  • blood flow to the kidneys, digestive tract and skin
  • interest in sex
  • tissue repair
  • immune system response

This state of stimulation contributes to physical and mental health problems, especially when stress is experienced for prolonged periods of time.

The Stress Management Society has a brief description of the "fight or flight" response

Videos that describe the "fight of flight" response include "Emotional Arousal: The Fight or Flight Reaction", "The Stress Response- Fight or Flight" and the "Fight or Flight clip"
