" high sensitivity describes people whose nervous systems are more receptive to stimuli than those of the general population. This means they are more attuned to subtleties in their surroundings and are more easily overwhelmed by highly stimulating environments. Their internal “radar” for detecting external stimuli is quite good, but it takes energy to keep that radar operational, which can be exhausting. "
