The influence of a time-shift of 6 hrs on the 24-hr rhythm of body temperature was investigated in a group of eight students in Germany and the U.S. by measuring their rectal temperatures after transatlantic flights. The temperatures were taken continuously over the first 6 days and on days 8 and 13 after an east-west flight and after a west-east flight. In contrast to previous studies in which the west flight was a day flight, the east flight a night flight, both flights in this case were day flights. The time of resynchronisation after the east-west flight ran up to 7 days, the time after a flight in the opposite direction up to 10 days. This result squares with the results gained from previous experiments on day and night flights insofar as an influence of the hour of the day at which the flight is carried out is not supposed.
