Changes of schedules larger than 3 h, such as jet lag and shift work, require an adjustment period of several days to resynchronize the sleep-wake cycle and several weeks to resynchronize other circadian rhythms to the new schedule. Initial studies on adaptation to small changes of schedule (1-2 h) found that the sleep-wake cycle adapts to the new schedule in less than 48 h, and such modifications are generally not studied because they may be confounded by a potential masking effect. This… 
Individual response to the end of Daylight Saving Time is largely dependent on habitual sleep duration
Adherence to the external clock by adjusting bed times and rise times was apparent on the first night, but difficulties in following this timing on subsequent nights point to a delay in full adjustment, particularly for those who habitually sleep for less than 7.5 h/night.
Morningness–eveningness and sleep patterns of adolescents attending school in two rotating shifts
The findings of this study suggest that the Croatian school system fosters sleep irregularity, but provides more opportunity for fulfilling sleep need of all chronotype groups of adolescents.
Month-to-month variation in sleep among healthy, Scandinavian daytime workers
Hours of daylight were found to be associated to self-reported bedtime and DSI and potential bias due to circa-annuality in the studied parameters appears to be of limited concern in adult daytime working populations.

While no significant sleep pattern change was found in this population due to change of clock times or weekend visits, larger epidemiological studies addressing other unexamined variables to better delineate changes in ASD are needed.
Morningness-Eveningness and Flextime Possibilities: Connections Between Circadian Rhythm, Work Day Schedule, Well-Being and Productivity
The current study aimed to investigate earlier reported connections to the morningnesseveningness dimension or flextime, and to offer an explanatory model linking these variables to well-being and

Influence of Chronotype, Season, and Sex of Subject on Sleep Behavior of Young Adults
Investigation of whether sex, season, and/or chronotype influence the sleep behavior of university students found no significant sex‐specific differences in sleep efficiency, sleep onset latency, or actual sleep‐time duration, but did find a difference insleep efficiency between morning and evening types.
The stress of travel
Sleep loss and its effects are important components of jet lag, and attempts to promote sleep by the use of melatonin and other hypnotics are also relevant.


Delaying and extending sleep during weekends: sleep recovery or circadian effect?
The findings suggest that the prolonged sleep during weekends is due to reduction of sleep during workdays, whereas the delay of bedtime seems to be associated with a tendency of the human circadian system to maintain a delayed phase with respect to the solar daylight period.
Sleep-wake as a biological rhythm.

A potent circadian cycle in the drive for wakefulness, which is generated by the suprachiasmatic nucleus is revealed, which reaches a peak during the evening hours just before habitual bedtime.
The Influence of Study Schedules and Work on the Sleep–Wake Cycle of College Students
College students usually exhibit an irregular sleep-wake cycle characterized by great phase delays on weekends and short sleep length on weekdays. As the temporal organization of social activities is
A single dose of melatonin prevents the phase delay associated with a delayed weekend sleep pattern.
A delayed weekend sleep pattern did show a mild phase-delay effect on the endogenous circadian rhythm, and a single dose of melatonin can acutely reverse the weekend drift.
Sleep schedules and peak times of oral temperature and alertness in morning and evening 'types'.
It is suggested that in normal conditions the coupling between temperature circadian rhythm and sleep-awake cycle differs in morning types and evening types.

The most commonly reported sleeping difficulty of this population of university first-year psychology students was frequent difficulty in falling asleep (18%), whereas only 9% of the sample had frequent difficulty staying asleep.
Adjusting to the changes to and from Daylight Saving Time
It is found that significant disruptions of behaviour occur during adaptation to the time change, and the adoption of Daylight Saving Time is another possible cause of disruption.
Exogenous Melatonin's Phase-Shifting Effects on the Endogenous Melatonin Profile in Sighted Humans: A Brief Review and Critique of the Literature
It is predicted that in the near future, melatonin administration will become as useful as bright light exposure in the treatment of circadian phase disorders.

Delayed sleep phase syndrome. A chronobiological disorder with sleep-onset insomnia.
A new syndrome called "delayed sleep phase insomnia" is described, which is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.
