SLEEP PATTERNS IN AIR TRAFFIC CONTROLLERS WORKING RAPIDLY ROTATING SHIFTS: A FIELD STUDY
This study was part of a research program in shift work and fatigue in the Air Traffic Control (ATC) environment. The purpose of the study was to investigate three different shift schedules in use at ATC facilities with respect to potential disruption of the sleep/wake cycle. A straight day schedule of early morning shifts (i.e., beginning before 0800), and two variations of counterclockwise, rapidly rotating shift schedules, the 2-2-1 and 2-1-2, were analyzed in terms of total sleep time, asleep and awake times, and subjective ratings of sleep quality and sleepiness. Data were collected in daily logbooks by air traffic control specialists. Neither subjective ratings of sleep quality or sleepiness were found to vary by schedule type. More 'high' ratings of sleepiness on the drive home, however, were reported following the midnight shift than any other shift.
