In this review, we propose several factors that may influence whether light has an alerting or sleep-promoting effect in mice. These include preceding sleep history, preceding light history, as well as the behavioural context in which light stimuli are delivered....
Light regulates daily sleep rhythms by a neural circuit that connects intrinsically photosensitive retinal ganglion cells (ipRGCs) to the circadian pacemaker, the suprachiasmatic nucleus. Light, however, also acutely affects sleep in a circadian-independ

Research has shown that exposure to bright white light or blue-enriched light enhances alertness, but this effect is not consistently observed in tasks demanding high-level cognition (e.g., Sustained Attention to Response Task—SART, which measures inhibitory control). Individual differences in sensit...
earlier in the day to gain this effect. Its low color temperature has a soothing effect on the body, and it’s the most conducive wavelength of light for a good night’s sleep. Using red light at night or in the evenings can help your body transition into its sleep cycle more ...
However, dim light can have an effect if it is delivered over long periods of time. Thus relatively dim indoor room light from bedside lamps and computer screens (less than 100 lux) can have measurable effects on the clock and arousal systems over several hours, and may exacerbate sleep ...
This study aims to evaluate the effect of light therapy on depression and sleep disruption in older adults residing in a long-term care facility. Psychological morbidity is a problem commonly seen in older adults residing in long-term care facilities. Limited research has addressed the effect of ...

Evening light-emitting visual displays may disrupt sleep, suppress melatonin and increase alertness. Here, we control melanopic irradiance independent of display luminance and colour, in 72 healthy males 4 h before habitual bedtime and expose each of
