When the "fight or flight" response has been triggered adrenaline, noradrenaline and cortisol is released into our bloodstream and our body begins to change. Our heart rate, respiratory rate and blood pressure increase, our pupils dilate and vision sharpens, blood glucose levels increase, muscles tense up, nonessential systems shut down to let for more energy be used by our muscles and limbs, which require extra energy and fuel for running and fighting.
