Mapping the Melatonin Suppression, Star Light and Induced Photosynthesis Indices with the LANcube

open access: yesRemote Sensing, 2020
Increased exposure to artificial light at night can affect human health including disruption of melatonin production and circadian rhythms which can extend to increased risks of hormonal cancers and other serious diseases.

Spatial sensitivity of human circadian response: Melatonin suppression from on-axis and off-axis light exposures

open access: yesNeurobiology of Sleep and Circadian Rhythms, 2021
A better understanding of the spatial sensitivity of the human circadian system to photic stimulation can provide practical solutions for optimized circadian light exposures. Two psychophysical experiments, involving 25 adult participants in Experiment 1

Artificial Light at Night Increases Aedes aegypti Mosquito Biting Behavior with Implications for Arboviral Disease Transmission.

open access: yesAmerican Journal of Tropical Medicine and Hygiene, 2020
Aedes aegypti mosquito is a major vector of arboviral disease. Here, we report that the biting behavior of normally daytime active anthropophilic Ae.

Beyond CCT: The spectral index system as a tool for the objective, quantitative characterization of lamps [PDF]

open access: yes, 2017
Correlated color temperature (CCT) is a semi-quantitative system that roughly describes the spectra of lamps. This parameter gives the temperature (measured in kelvins) of the black body that would show the hue more similar to that of the light emitted ...

Associations of Sleep and Shift Work With Osteoarthritis Risk

open access: yesArthritis Care &Research, EarlyView.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift

Anisotropic characteristic of artificial light at night – Systematic investigation with VIIRS DNB multi-temporal observations

open access: yesRemote Sensing of Environment, 2019
The released VIIRS DNB nightly images, also known as VIIRS DNB daily nighttime images, provide rich information for time series analysis of global socioeconomic dynamics.

Light-at-night, cancer and aging

open access: yesAging, 2010
Recently, the International Agency for Research on Cancer (IARC) concluded that "shift-work that involves circadian disruption is probably carcinogenic to humans" [1]. This conclusion was based upon limited evidence in humans [2,3] and sufficient evidence in experimental animals [4,5]. The current experimental results of Vinogradova and colleagues from

The Effects of Light at Night on Circadian Clocks and Metabolism [PDF]

open access: yesEndocrine Reviews, 2014
Most organisms display endogenously produced ∼ 24-hour fluctuations in physiology and behavior, termed circadian rhythms. Circadian rhythms are driven by a transcriptional-translational feedback loop that is hierarchically expressed throughout the brain and body, with the suprachiasmatic nucleus of the hypothalamus serving as the master circadian ...

Adverse health effects of nighttime lighting: comments on american medical association policy statement. [PDF]

open access: yes, 2013
The American Medical Association House of Delegates in June of 2012 adopted a policy statement on nighttime lighting and human health. This major policy statement summarizes the scientific evidence that nighttime electric light can disrupt circadian ...
