When travelers move quickly across time zones, the circadian clock gets desynchronized from the exterior world, an experience most people know as jet lag. More movement during the night and less movement during the day, indicates disturbed sleep, as well as disrupted sleep/wake circadian rhythms. Despite regulations limiting flight time and enabling optimal rostering, fatigue cannot be prevented completely.
