• it's a suvival instinct in humans
• it gives the body an "adrenaline rush"
• the body gets tense and ready for action
• there is uncontrollable yelling
One common response to stressful or dangerous situations that is not part of the fight or flight response is the "startle response." The startle response is an instinctual reaction to a sudden and unexpected stimulus, causing the body to momentarily freeze, followed by a brief period of heightened alertness. This response is often accompanied by a quick intake of breath, widened eyes, and sometimes a reflexive jump or flinch. While the startle response shares some similarities with fight or flight, it does not involve the same level of physiological and psychological changes, nor does it result in uncontrollable yelling. Rather, the startle response is a reflexive mechanism aimed at preparing the body to assess and respond to potential threats.
