Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults

PLoS Biology, 2022
Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms and sleep, as well as neuroendocrine and cognitive functions.

Melanopic irradiance defines the impact of evening display light on sleep latency, melatonin and alertness

Communications Biology, 2023
An analysis of sleep patterns and melatonin concentrations in a cohort of male participants exposed to varying luminance levels commonly experienced in the evening showed that melanopic irradiance is a meaningful target for efforts to limit the impact of

The evening complex integrates photoperiod signals to control flowering in rice

Proceedings of the National Academy of Sciences of the United States of America, 2022
Significance Plants use photoperiod information to control flowering. Flowering in rice is accelerated by short days, while other plants, such as Arabidopsis, flower in response to long days.

The effect of morning vs evening exercise training on glycaemic control and serum metabolites in overweight/obese men: a randomised trial

Diabetologia, 2021
We determined whether the time of day of exercise training (morning vs evening) would modulate the effects of consumption of a high-fat diet (HFD) on glycaemic control, whole-body health markers and serum metabolomics.

A critical role of the soybean evening complex in the control of photoperiod sensitivity and adaptation

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance In many plant species, the timing of flowering is sensitive to photoperiod. In many crop species, genetic variation in this sensitivity is critical for adaptation to specific regions and management practices.

Evening-types show highest increase of sleep and mental health problems during the COVID-19 pandemic—multinational study on 19 267 adults

Sleep, 2021
Study Objectives Individual circadian type is a ubiquitous trait defining sleep, with eveningness often associated with poorer sleep and mental health than morningness.

Preliminary Results: The Impact of Smartphone Use and Short-Wavelength Light during the Evening on Circadian Rhythm, Sleep and Alertness

Clocks & Sleep, 2021
Smartphone usage strongly increased in the last decade, especially before bedtime. There is growing evidence that short-wavelength light affects hormonal secretion, thermoregulation, sleep and alertness.

Evening chronotype is associated with poor cardiovascular health and adverse health behaviors in a diverse population of women

Chronobiology International, 2020
Chronotype reflects time of day preferences for performing daily activities. Previous research within Asian and European cohorts indicates evening chronotype is associated with elevated cardiometabolic risk.

Evening home lighting adversely impacts the circadian system and sleep

Scientific Reports, 2020
The regular rise and fall of the sun resulted in the development of 24-h rhythms in virtually all organisms. In an evolutionary heartbeat, humans have taken control of their light environment with electric light. Humans are highly sensitive to light, yet

Reference intervals for urinary cotinine levels and the influence of sampling time and other predictors on its excretion among italian schoolchildren [PDF]

, 2018
(1) Background: Environmental Tobacco Smoke (ETS) exposure remains a public health problem worldwide. The aims are to establish urinary (u-) cotinine reference values for healthy Italian children, to evaluate the role of the sampling time and of other ...
