Both introverts and extroverts use both sides of their nervous systems at different times, just like they use both neurotransmitters.But—no big shocker here—extroverts tend to favor the opposite side of the nervous system: the sympathetic side, known as the “full-throttle” or “fight, flight, or freeze” system.It powers our abilities to think deeply, reflect, and focus intensely on just one thing for a long period of time.It also helps explain why introverts like calm environments—it’s easier to turn inward when we’re not attending to external stimulation.
In fact, this intensity of stimulation acted as a cue to them that they were achieving their goal (the reward of socializing and a fun night out).
Our muscles relax; energy is stored; food is metabolized; pupils constrict to limit incoming light; and our heart rate and blood pressure lower.
Basically, our body gets ready for hibernation and contemplation—two of the things introverts like the most.
They’ll actually feel energized when they leave and won’t need any recovery time.
So, why do I react so differently than my extroverted friends to the same situation?
