    “

    The suspicion you feel at midnight might actually be a seed planted by the exhaustion you felt at noon; your nighttime anxiety is the price you pay for the biological necessity of rest.

    よくある質問

    Nighttime paranoia is a complex psychological and biological phenomenon where individuals feel an inexplicable sense of suspicion or threat during the night. It often manifests as hyper-awareness of shadows or sounds, like a floorboard's creak, which can cause the heart to race. This experience is deeply rooted in our evolutionary heritage, occurring when sleep deprivation, anxiety, and our history as a diurnal species collide to create irrational fears of harm.

    The sentinel response is an ancient biological survival mechanism designed to protect our ancestors from predators or enemies. Because humans are a diurnal species, we are naturally vulnerable in the dark due to a significant drop in our visual monitoring capabilities. Feeling a surge of suspicion while trying to fall asleep is essentially the body activating this life-saving skill, turning nighttime hyper-awareness into a protective tool for the species.

    Irrational fears of harm by others are more common than many people realize, affecting approximately 15 to 20 percent of the general population on a regular basis. These feelings are not merely a result of a bad mood or an overactive imagination. Instead, they represent a significant intersection of biological anxiety and evolutionary traits that once helped humans survive dangerous environments when their daytime confidence vanished in the darkness.
