Entrainment of rest-activity cycles and plasma melatonin rhythms by a forced schedule was examined in humans who were held in temporal isolation with dim light conditions (<10 lx). The sleep schedule of subjects was phase-advanced by approximately 8 h from the habitual sleep time for 8 days, which was followed by a free-running session where the subjects self-determined the times of sleep and wake up for 6 days. As a result, the rest-activity cycle was advanced by 8.2 h on the first day of free… 
Differential regulation of circadian melatonin rhythm and sleep-wake cycle by bright lights and nonphotic time cues in humans.
TLDR
Polysomnographical analyses revealed that deterioration of sleep quality by shift schedule was protected by physical exercise under bright lights, indicating differential regulation of sleep-wake cycle and circadian melatonin rhythm by physical Exercise in humans.
Physical exercise accelerates reentrainment of human sleep-wake cycle but not of plasma melatonin rhythm to 8-h phase-advanced sleep schedule.
TLDR
Findings indicate that the reentrainment of the sleep-wake cycle to a phase-advanced schedule occurs independent of the circadian pacemaker and is accelerated by timed physical exercise.
Phase-adjustment of human circadian rhythms by light and physical exercise
TLDR
Physical exercise may enhance the phase-shift of circadian rhythm caused by bright light by changing light perception, and is important to enable elite athletes to take a good sleep and enhance exercise performance, especially after inter-continental travel and jet lag.
Revisiting Spontaneous Internal Desynchrony Using a Quantitative Model of Sleep Physiology
TLDR
A physiologically based model of hypothalamic and brain stem nuclei is used to investigate alternative physiological mechanisms that could underlie internal desynchrony, and it is demonstrated that experimental observations can be reproduced by changes in two pathways: promotion of orexinergic wake signals, and attenuation of the circadian signal reaching hypothalamic nuclei.
Morning and evening physical exercise differentially regulate the autonomic nervous system during nocturnal sleep in humans.
Effects of daily physical exercise in the morning or in the evening were examined on circadian rhythms in plasma melatonin and core body temperature of healthy young males who stayed in an
A fixed single meal in the subjective day prevents free-running of the human sleep-wake cycle but not of the circadian pacemaker under temporal isolation.
TLDR
Findings indicate that a single meal at fixed time of day during the subjective day failed to prevent the human circadian pacemaker but prevented the sleep-wake cycle to free-run at least 8 days under temporal isolation, suggesting that meal time was a potent non-photic time cue for the human sleep- wake cycle.
Repeated exposures to daytime bright light increase nocturnal melatonin rise and maintain circadian phase in young subjects under fixed sleep schedule.
TLDR
Exposure to daytime bright light is shown to be effective in controlling the circadian phase and increasing the peak level of nocturnal melatonin rise in plasma and a close correlation between phase-delay shifts of the onset ofNocturnalmelatonin rise or body temperature rhythm and daytime sleepiness is suggested.
Integrated model incorporating circadian phase dynamics and the thermoregulatory mechanism of sleep
Recently, physiological findings have suggested the existence of an integrated regulatory mechanism for sleep-wake rhythms, as follows. Homeostatic regulation of the sleep-wake pattern and body
The SCN‐independent clocks, methamphetamine and food restriction
TLDR
The SCN‐independent clock is an adaptation that regulates behavior in response to nonphotic time cues, and seems to be closely related to the arousal mechanism.
Top-down modeling of hierarchical biological clock mechanisms
The behavior of human circadian rhythms could be interpreted within the two-oscillator regime: one for the circadian pacemaker driving temperature/plasma melatonin rhythm and the other for the

Phase-advance shifts of human circadian pacemaker are accelerated by daytime physical exercise.
TLDR
It is indicated that physical exercise accelerates phase-advance shifts of the human circadian pacemaker associated with the forced sleep-wake schedule and significantly phase advanced plasma melatonin rhythm.
After-effect of entrainment on the period of human circadian system.
TLDR
The free-run period of rectal temperature rhythm was steadily lengthened throughout the isolation period, which was probably due to the after-effect of previous entrainment to 24-h time cues.
A Phase Dynamics Model of Human Circadian Rhythms
TLDR
A phase dynamics model that consisted of two oscillators driving temperature/melatonin and sleep-wake rhythms, and an additional oscillator generating an overt sleep- wake rhythm successfully simulated the behavior of human circadian rhythms in response to forced rest-activity schedules under free-run situations.
Light and plasma melatonin rhythm in humans.
TLDR
It is concluded that the plasma melatonin rhythm is the best marker of the human circadian pacemaker so far available.
Phase‐shifting human circadian rhythms: influence of sleep timing, social contact and light exposure.
TLDR
The data indicate that interventions designed to phase shift human circadian rhythms for adjustment to time zone changes or altered work schedules should focus on properly timed light exposure, and support the concept that the light‐dark cycle is the most important synchronizer of the human circadian system.
Melatonin rhythm is not shifted by lights that suppress nocturnal melatonin in humans under entrainment.
TLDR
It is concluded that the threshold of light intensity for suppressing the melatonin level is located between 200 and 500 lx in young Japanese males, and the threshold for phase shifting the circadian melatonin rhythm was much greater than that for suppress the nocturnalmelatonin level in humans under entrained conditions.
Intrinsic near-24-h pacemaker period determines limits of circadian entrainment to a weak synchronizer in humans
TLDR
It is reported here that imposition of a sleep–wake schedule with exposure to the equivalent of candlelight during wakefulness and darkness during sleep is usually sufficient to maintain circadian entrainment to the 24-h day but not to a 23.5- or 24.6-H day.
Timing of human sleep: recovery process gated by a circadian pacemaker.
TLDR
The model shows that the experimental data are consistent with the concept of a single circadian pacemaker in humans, which has implications for the understanding of sleep as a restorative process and its timing with respect to day and night.
Free‐running circadian rhythm of melatonin in a sighted man despite a 24‐hour sleep pattern: A non‐24‐hour circadian syndrome
TLDR
It is concluded that internal desynchronization occurred in this particular sighted subject where the sleep‐wake rhythm was entrained by the 24‐hour day‐night environment, whereas the plasma melatonin rhythm free ran, and that a forced sleep schedule did not act as a strong zeitgeber.
A behavioural method for accelerating re-entrainment of rhythms to new light—dark cycles
TLDR
The rate of re-entrainment of hamsters could be more than doubled simply by making the animals active on a single occasion in the middle of their normal rest period, immediately after the shift in the LD cycle.
