Circadian rhythms are internal manifestations of the solar day that permit adaptations to
predictable environmental temporal changes. These~ 24-h rhythms are controlled by …

Sleep represents an emergent set of many physiologic processes under primarily
neurobiological regulation that impact many physiologic systems. As such, many advances …

Research on precarious work and its consequences overwhelmingly focuses on the
economic dimension of precarity, epitomized by low wages. But the rise in precarious work …

Shift work is associated with impaired alertness and performance due to sleep loss and
circadian misalignment. This study examined sleep between shift types (day, evening …

Temporal organization of physiology is critical for human health. In the past, humans
experienced predictable periods of daily light and dark driven by the solar day, which …

Melatonin modulates a wide range of physiological functions with pleiotropic effects on the
immune system. Despite the large number of reports implicating melatonin as an …

Features of an individual's sleep/wake patterns across multiple days are governed by two
dimensions, the mean and the intraindividual variability (IIV). The existing literature focuses …

Most organisms display endogenously produced∼ 24-hour fluctuations in physiology and
behavior, termed circadian rhythms. Circadian rhythms are driven by a transcriptional …

Sleep represents a set of biological functions necessary for the maintenance of life.
Performing these functions, though, requires that an individual engage in behaviors, which …

Human behavior shows large interindividual variation in temporal organization. Extreme
“larks” wake up when extreme “owls” fall asleep. These chronotypes are attributed to …
