Sleep history and circadian rhythms influence human sleep cycles and dream times
Current chronobiological and sleep research consistently shows that sleep history and circadian rhythms directly regulate human sleep cycles and architecture, including REM sleep duration.
The retrieved papers extensively document the physiological links between circadian rhythms, sleep-wake history, sleep architecture, and specific sleep stages (such as REM sleep). Multiple studies confirm that circadian entrainment, phase alignment, and prior sleep history impact sleep cycles and sleep duration. Therefore, the claim is well-supported by the scientific evidence.

Paper [0] demonstrates that circadian adaptation and the alignment of the sleep-wake cycle significantly influence sleep architecture and REM sleep duration.
