Visible light synchronizes the human biological clock in the suprachiasmatic nuclei of the
hypothalamus to the solar 24‐hour cycle. Short wavelengths, perceived as blue color, are …

Mammalian circadian rhythms are controlled by endogenous biological oscillators, including
a master clock located in the hypothalamic suprachiasmatic nuclei (SCN). Since the period …

Human circadian, neuroendocrine, and neurobehavioral responses to light are mediated
primarily by melanopsin-containing intrinsically-photosensitive retinal ganglion cells …

To date, most current reports on the development and optimization of artificial lighting
sources have focused on the energy performance levels and limited color qualities of white …

Melatonin is a neurohormone known to modulate a wide range of circadian functions,
including sleep. The synthesis and release of melatonin from the pineal gland is heavily …

Light can impact human health via the visual and non-visual systems originating in the retina
of the eye or as optical radiation falling on eye or skin. This paper provides a summary of …

The effect of light on circadian rhythms and sleep is mediated by a multi‐component
photoreceptive system of rods, cones and melanopsin‐expressing intrinsically …

Circadian clocks evolved under conditions of environmental variation, primarily alternating
light dark cycles, to enable organisms to anticipate daily environmental events and …

Abstract Study Objectives: Light can induce an acute alerting response in humans; however,
it is unknown whether the magnitude of this response is simply a function of the absolute …

The circadian timing system plays a key role in orchestrating lipid metabolism. In concert
with the solar cycle, the circadian system ensures that daily rhythms in lipid absorption …
