The "fight or flight" response is our body's primitive, automatic response that prepares the body to "fight" or "flee" from perceived attack, harm, or threat to survival.

When the "fight or flight" response is activated, chemicals like adrenaline and cortisol are released into the blood stream. The rate of respiration increases, blood is redirected from the digestive system into the muscles and limbs; which require extra energy for running and fighting, pupils dilate, awareness intensifies, sight sharpens, impulses quicken, perception of pain diminishes, and immune response intensifies.
