Sleep health has multiple dimensions including duration, regularity, timing, and quality [1–4].
The Coronavirus 2019 (COVID-19) outbreak led to Stay-at-Home orders and Social …

Circadian rhythms are endogenous and need to be continuously entrained (synchronized)
with the environment. Entrainment includes both coupling internal oscillators to external …

Daily interactions between the hypothalamic circadian clock at the suprachiasmatic nucleus
(SCN) and peripheral circadian oscillators regulate physiology and metabolism to set …

Before the availability of artificial light, moonlight was the only source of light sufficient to
stimulate nighttime activity; still, evidence for the modulation of sleep timing by lunar phases is …

Metabolic functions are synchronized by the circadian clock setting daily patterns of food
intake, nutrient delivery, and behavioral activity. Here, we study the impact of chronic jet‐lag ( …

We studied locomotor activity rhythms of C57/Bl6 mice under a chronic jet lag (CJL) protocol
(ChrA 6/2 ), which consisted of 6-hour phase advances of the light-dark schedule (LD) every …

Key to the transition of humans from nomadic hunting‐gathering groups to industrialized and
highly urbanized societies was the creation of protected and artificially lit environments that …

We show that nocturnal aversive stimuli presented to mice while they are eating and drinking
outside of their safe nest can entrain circadian behaviors, leading to a shift toward daytime …

In this study, we tested the prediction that sleep regularity would be lower in adolescents
exposed to late evening electric light (LEEL) than in those without exposure to it. The Sleep …

Diabetic retinopathy is a leading cause of blindness. Intrinsically photosensitive retinal
ganglion cells (ipRGCs), which express the photopigment melanopsin, are involved in non-image-…
