Life between Clocks: Daily Temporal Patterns of Human Chronotypes
TLDR
It is predicted that the timing of sleep has changed during industrialization and that a majority of humans are sleep deprived during the workweek, and the implications are far ranging concerning learning, memory, vigilance, performance, and quality of life. Expand
A marker for the end of adolescence
TLDR
Investigating ‘chronotypes' observed an abrupt change in the timing of sleep at around the age of 20 and propose this change as the first biological marker of the end of adolescence. Expand
Social Jetlag: Misalignment of Biological and Social Time
Humans show large differences in the preferred timing of their sleep and activity. This so‐called “chronotype” is largely regulated by the circadian clock. Both genetic variations in clock genes andExpand
Epidemiology of the human circadian clock.
TLDR
An algorithm is established which optimises chronotype assessment by incorporating the information on timing of sleep and wakefulness for both work and free days, because sleep duration strongly depends on chronotype. Expand
Social Jetlag and Obesity
TLDR
The results demonstrate that living "against the clock" may be a factor contributing to the epidemic of obesity, and suggest that improving the correspondence between biological and social clocks will contribute to the management of obesity. Expand
Peroxiredoxins are conserved markers of circadian rhythms
TLDR
It is shown that oxidation–reduction cycles of peroxiredoxin proteins constitute a universal marker for circadian rhythms in all domains of life, by characterizing their oscillations in a variety of model organisms and exploring the interconnectivity between these metabolic cycles and transcription–translation feedback loops of the clockwork in each system. Expand
The Human Circadian Clock's Seasonal Adjustment Is Disrupted by Daylight Saving Time
TLDR
The data indicate that the human circadian system does not adjust to DST and that its seasonal adaptation to the changing photoperiods is disrupted by the introduction of summer time, which may extend to other aspects of seasonal biology in humans. Expand
Social jetlag and obesity.
TLDR
The results demonstrate that living "against the clock" may be a factor contributing to the epidemic of obesity, and suggest that improving the correspondence between biological and social clocks will contribute to the management of obesity. Expand

The Art of Entrainment
TLDR
Understanding entrainment is equal to understanding the circadian system and the results of this basic research will help to understand temporal ecology and will allow to improve conditions for humans in industrialized societies. Expand
