Finding it hard to cope with jet lag, shift-based work? Doing some exercise can shift the human body clock and help you adjust to the shifted schedules, suggests new research.
The study, from Arizona State University, showed that exercise can shift the human body clock with the direction and amount of this effect depending on the time of day or night in which people exercise.
Exercising at 7am or between 1 and 4pm advanced the body clock to an earlier time, and exercising between 7 and 10pm. delayed the body clock to a later time.
Exercising between 1 and 4am and at 10am however, had little effect on the body clock, and the phase-shifting effects of exercise did not differ based on age or gender, the researchers explained.
"Exercise has been known to cause changes to our body clock. We were able to clearly show in this study when exercise delays the body clock and when it advances it," said lead author Shawn Youngstedt, from the varsity.
