Optimized office lighting advances melatonin phase and peripheral heat loss prior bedtime

Jean-Louis Scartezzini, Mirjam Münch, Marta Benedetti, Lenka Maierova

Improving indoor lighting conditions at the workplace has the potential to support proper circadian entrainment of hormonal rhythms, sleep, and well-being. We tested the effects of optimized dynamic daylight and electric lighting on circadian phase of mela ...

Oscillating and stable genome topologies underlie hepatic physiological rhythms during the circadian cycle

Felix Naef, Jake Yeung, Jérôme Mermet

The circadian clock drives extensive temporal gene expression programs controlling daily changes in behavior and physiology. In mouse liver, transcription factors dynamics, chromatin modifications, and RNA Polymerase II (PolII) activity oscillate throughou ...

Dealing with Daily Rhythms: Families’ Strategies to Tackle Chronic Time Pressure

Vincent Kaufmann, Guillaume Simon Joseph Drevon, Philippe Gerber

As suggested by the conservation of resources theory, in contemporary societies time is considered as a limited resource in the same way as money and energy. In the current paper, a novel daily rhythm approach related to motility is presented, in order to ...

Temperature regulates splicing efficiency of the cold-inducible RNA-binding protein gene Cirbp

Felix Naef, Saeed Omidi Klishami

In mammals, body temperature fluctuates diurnally around a mean value of 36 degrees C-37 degrees C. Despite the small differences between minimal and maximal values, body temperature rhythms can drive robust cycles in gene expression in cultured cells and, ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

Sex difference in the near-24-hour intrinsic period of the human circadian timing system

Mirjam Münch

The circadian rhythms of melatonin and body temperature are set to an earlier hour in women than in men, even when the women and men maintain nearly identical and consistent bedtimes and wake times. Moreover, women tend to wake up earlier than men and exhi ...

Preliminary Method for Prospective Analysis of the Circadian Efficacy of (Day)Light with Applications to Healthcare Architecture

Marilyne Andersen, Steven W. Lockley

Recent studies have attempted to link environmental cues, such as lighting, with human performance and health, and initial findings seem to indicate a positive correlation between the two. Light is the major environmental time cue that resets the human cir ...

Cellular oscillators: rhythmic gene expression and metabolism

Felix Naef

Many biological processes are driven by biological clocks that, depending on the frequency they generate, are classified into ultradian, circadian and infradian oscillators. In virtually all light-sensitive organisms from cyanobacteria to humans, a circadi ...
