Light timing and spectrum shift or stabilize biological timing
family: Circadian
ND-0012 · 2018 · Review
A review of the environmental parameters necessary for an optimal sleep environment
Authors per journal record. Building and Environment
Noise, temperature, light and air quality each have plausible and documented effects on sleep quality and continuity.
ND-0013 · 2012 · Review
Effects of thermal environment on sleep and circadian rhythm
Okamoto-Mizuno & Mizuno. Journal of Physiological Anthropology
Heat and cold exposures can increase wakefulness and reduce REM or slow-wave sleep, with thermoregulation tightly coupled to sleep.
ND-0037 · 2019 · Review
Effects of light on human circadian rhythms, sleep and mood
Blume, Garbazza & Spitschan. Somnologie
Light timing, spectrum and intensity can alter circadian rhythms, sleep and mood through retinal pathways beyond image-forming vision.
ND-0038 · 2014 · Case-control pilot study
Impact of Windows and Daylight Exposure on Overall Health and Sleep Quality of Office Workers
Boubekri et al. Journal of Clinical Sleep Medicine
Workers with more window/daylight exposure reported better sleep and wellbeing and had longer sleep duration in actigraphy analyses.
ND-0039 · 2026 · Naturalistic observational study
Naturalistic light exposure patterns in relation to medication status, mood symptoms, and chronotype
Authors per journal record. npj Biological Timing and Sleep
Naturalistic light patterns differed in relation to chronotype and mood-related variables, reinforcing the importance of real-world exposure timing.
ND-0040 · 2026 · Descriptive field study
Sleep and light ecologies of parents with young infants: descriptive findings from the SUNSHINE project
Authors per journal record. npj Biological Timing and Sleep
Documents real-world light and sleep patterns in a population with fragmented sleep and distinctive household routines.
ND-0100 · 2018 · Standard
CIE S 026/E:2018: CIE System for Metrology of Optical Radiation for ipRGC-Influenced Responses to Light
CIE. International Commission on Illumination
Defines metrics for quantifying optical radiation relevant to the five retinal photoreceptor classes involved in non-visual light responses.
