Airports are scientifically designed "liminal spaces" that often trigger a sense of loss of control, a primary driver of psychological stress. From the moment you enter, your movement is regulated by strict routines, security checkpoints, and deadlines that are entirely out of your hands. Environmental psychology in 2026 points to "sensory overload" as another major culprit: the constant barrage of announcements, bright fluorescent lighting, and large, fast-moving crowds can overwhelm the nervous system. The "Will I make it?" anxiety regarding flight times and gate changes keeps travelers in a state of high alert. Furthermore, the removal of personal agency—having to take off your shoes, open your bags, and be searched—can feel invasive, making the airport a unique crossroads of physical exhaustion and mental high-tension.
