INFLUENCE OF THE JOURNEY'S TIME OF DAY ON THE DE- AND RESYNCHRONIZATION OF THE 24-HOUR RHYTHM OF BODY TEMPERATURE AFTER TRANSATLANTIC FLIGHTS

The influence of a time-shift of 6 hours on the 24-hour rhythm of body temperature was investigated in a group of eight students in Germany and the U.S.A. by measuring their rectal-temperatures after transatlantic flights. The temperatures were taken continuously over the first six 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 day-flight, the east flight a night-flight, both flights in this case were day-flights. The time of resynchronization after the east-west flight ran up to seven days, the time after a flight in the opposite direction up to ten days. This result squares with the results gained from previous experiments on day and night flights in so far as an influence of the hour of the day, at which the flight is carried out, is not supposed.
