Light-emitting diodes (LEDs) have been used to provide illumination in industrial and
commercial environments. LEDs are also used in TVs, computers, smart phones, and …

In humans, sleep and wakefulness and the associated cognitive processes are regulated
through interactions between sleep homeostasis and the circadian system. Chronic …

With the rapid development of artificial intelligence, the simulation of the human brain for
neuromorphic computing has demonstrated unprecedented progress. Photonic artificial …

With aging, significant changes in circadian rhythms occur, including a shift in phase toward
a “morning” chronotype and a loss of rhythmicity in circulating hormones. However, the …

Purpose The objective of this study was to find out the association between mobile use and
physiological parameters of poor sleep quality. It also aimed to find out the prevalence of …

Daily variations in the environment have shaped life on Earth, with circadian cycles
identified in most living organisms. Likewise, seasons correspond to annual environmental …

Light use is rising steeply, mainly because of the advent of light-emitting diode (LED)
devices. LEDs are frequently blue-enriched light sources and may have different impacts on …

Notwithstanding its effects on the classical visual system allowing image formation, light acts
upon several non-image-forming (NIF) functions including body temperature, hormonal …

Abstract Study Objectives: Prolonged exposure to blue wavelength light has been shown to
have an alerting effect, and enhances performance on cognitive tasks. A small number of …

In the context of geriatric research, a growing body of evidence links normal age-related
changes in sleep with many adverse health outcomes, especially a decline in cognition in …
