The fight or flight response is important and adaptive in situations where we need to deal with a stressor RIGHT NOW–like when you need to run away from danger or defend yourself against an attacker. But the fight or flight response can also arise in comparatively mild social situations (such as having a tense conversation with your boss at work) and even when you simply think about something stressful that may not happen until years from now (like the fact that your life will not go on forever). While the fight or flight response is adaptive in helping you to take urgent action, ongoing psychological stress can cause health problems, especially digestive and cardiovascular issues (due primarily to the effects of stress hormones on the body). All of this begins with a tiny brain region known as the amygdala. If you want to learn more about this and the amygdala in general, check out the latest video on my YouTube channel (https://youtu.be/fXuZpMiSGHk) Hearing animation credit: wikipedia.org Thanks for your time and I hope you have a great day.
