Title The effect of four-day round trip flights over 10 time zones on the sleep-wakefulness patterns of airline flight attendants
Bibliographic information Sep. 1994, Vol.37, No.9, p.1461-1478. Illus. 24 ref.
Abstract Forty flight attendants kept daily logs on sleepiness, the time they went to bed, and sleep quality during a four-day round trip flight over ten time zones. The autonomic sleep phases of 21 subjects were studied using the static charge sensitive bed method. Most flight attendants suffered significant disturbances in sleep quality. Sleep disturbance increased after both westward and eastward flights, but differed from each other in specific features. Recovery from the four-day trip took on average four days.
