“Over 97 percent of rhythmic genes became out of sync with mistimed sleep and this really explains why we feel so bad during jet lag, or if we have to work irregular shifts,” said co-author Simon Archer from the school of biosciences and medicine.

The study also revealed which genes may be regulated by sleep-wake cycles and which are regulated by central body clocks.

This finding provides new clues about sleep's function as separate from the circadian clock.

“The results also imply that sleep-wake schedules can be used to influence rhythmicity in many biological processes, which may be very relevant for conditions in which our body clocks are altered, such as in aging,” added professor Derk-Jan Dijk.
