[Behavior of the human organism in time zone flights. 2. Sequelae of desynchronization].

The responses of the human organism to time zone flights are reviewed. The physical and biological principles which are connected with dysrhythmic phenomena following shifts of environmental time cues are demonstrated. Quantity and quality of desynchronotic symptoms of psychophysiological functions are described and their significance for performance ability and health of the air traveller, in particular with respect to the possibility of pathogeneous effects, are discussed.
