Physiological effects of light exposure in humans are diverse. Among them, the circadian
rhythm phase shift effect in order to maintain a 24-h cycle of the biological clock is referred to …

Circadian rhythms refer to oscillations in biological processes with a period of approximately
24 h. In addition to the sleep/wake cycle, there are circadian rhythms in metabolism, body …

Abstract Study Objectives: Individual differences in sleep timing have been widely
recognized and are of particular relevance in adolescents and young adults who often show …

Sleep deprivation, in the context of shift work, is an increasing major public health issue. We
aimed to determine whether early light administration can counteract sleep deprivation …

Purpose To evaluate the ability of chromatic pupillometry to reveal abnormal pupillary
responses to light in patients with early-stage primary open-angle glaucoma (POAG) and to …

Idiopathic hypersomnia (IH), characterized by an excessive day-time sleepiness, a
prolonged total sleep time on 24 h and/or a reduced sleep latency, affects 1 in 2000 …

ABSTRACT Circadian Rhythm Sleep-Wake Disorders (CRSWDs) are important sleep
disorders whose unifying feature is a mismatch between the preferred or required times for …

Mood states in bipolar disorder appear to be closely linked to changes in sleep and
circadian function. It has been suggested that hypersensitivity of the circadian system to light …

Purpose: The purpose of this study was to evaluate a chromatic pupillometry protocol for
specific functional assessment of rods, cones, and intrinsically photosensitive retinal …

Abstract Study Objectives Altered comfort sensing and reduced gray matter volume in the
orbitofrontal cortex of the brain in people suffering from insomnia disorder (ID) suggest …
