The non-visual effects of light have become a hot topic in the study of how lighting
environments affect humans. For an extended time, living and working in an isolated …

This paper reports the results of a systematic review conducted on articles examining the
effects of daytime electric light exposure on alertness and higher cognitive functions. For …

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 …

Sleep deprivation is known to have adverse effects on various cognitive abilities. In
particular, a lack of sleep has been reported to disrupt memory consolidation and cognitive …

To better understand the impact of environmental light on processes that underlie cognitive
activity, Lasauskaite and Cajochen (2018) recently proposed a theoretical model that …

Light at night can improve alertness and cognition. Exposure to daytime light, however, has
yielded less conclusive results. In addition to direct effects, daytime light may also mitigate …

The relationship between daytime light, especially morning light and sleep, has not been
well documented. People who work in an office spend most of their time indoors and thus …

Objectives Under laboratory settings, light exposure upon waking at night improves sleep
inertia symptoms. We investigated whether a field-deployable light source would mitigate …

We examined the impact of an 8-h exposure to short-wavelength-enriched white light during
the day on the cognitive performance, alertness, and mood of moderately sleep-restricted …

This perspective considers the possibility that daytime's intrusion into night made possible
by electric lighting may not be as pernicious to sleep and circadian health as the …
