Acute Stress Response

The Acute stress response (likewise called hyper arousal,) is a physiological response that happens because of an apparent destructive event, assault, or threat to survival. It was first portrayed by Walter Bradford Cannon. His hypothesis expresses that creatures respond to dangers with a general release of the sympathetic nervous system, preparing the creature for fighting or fleeing. All the more particularly, the adrenal medulla delivers a hormonal cascade that result in the secretion of catecholamines, particularly norepinephrine and epinephrine. The hormones estrogen, testosterone, and cortisol, and also the neurotransmitters dopamine and serotonin, likewise influence how living beings respond to stress
