“…However, the proper timing of exercise and its potential added benefit of improving circadian entrainment have not been investigated thoroughly. Disruption of circadian rhythms (e.g., by shift work, social jetlag, early-morning schedules) is associated with metabolic disorders, cardiovascular disease, and cancer (6)(7)(8)(9)(10)(11). If exercise could reduce circadian disruption, then it may also improve the risk factors associated with this disruption.…”

“…Numerous studies have shown that circadian disruption is a health risk. Shift work chronically disrupts the circadian system and is also associated with increased risk of cancer, obesity, and cardiovascular disease (6)(7)(8)(9)(10)(11). Nonshift workers also experience chronic forms of circadian disruption.…”

“…Alterations in the photoperiod (known as chronodisruption) and can interfere with healthy, term pregnancies and have long-term effects on normal offspring [219,220,221]. Artificial LAN has been linked to obesity at the international level [222]. Thus, walkable neighborhoods, quality green space and opportunity for outdoor activity, coincident with lower evening screen time, is connected to sleep hygiene.…”

The influential scientist Rene J. Dubos (1901–1982) conducted groundbreaking studies concerning early-life environmental exposures (e.g., diet, social interactions, commensal microbiota, housing conditions) and adult disease. However, Dubos looked beyond the scientific focus on disease, arguing that “mere survival is not enough”. He defined mental health as fulfilling human potential, and expressed concerns about urbanization occurring in tandem with disappearing access to natural environments (and elements found within them); thus modernity could interfere with health via “missing exposures”. With the advantage of emerging research involving green space, the microbiome, biodiversity and positive psychology, we discuss ecological justice in the dysbiosphere and the forces—financial inequity, voids in public policy, marketing and otherwise—that interfere with the fundamental rights of children to thrive in a healthy urban ecosystem and learn respect for the natural environment. We emphasize health within the developmental origins of health and disease (DOHaD) rubric and suggest that greater focus on positive exposures might uncover mechanisms of resiliency that contribute to maximizing human potential. We will entrain our perspective to socioeconomic disadvantage in developed nations and what we have described as “grey space”; this is a mental as much as a physical environment, a space that serves to insidiously reinforce unhealthy behavior, compromise positive psychological outlook and, ultimately, trans-generational health. It is a dwelling place that cannot be fixed with encephalobiotics or the drug-class known as psychobiotics.

“…The big discussion is about the health issues of light (in particular blue light during the night) and the impact on circadian rhythm. There are studies about the increased risk of breast cancer for women and prostate cancer for men related to ALAN [14], and of a link between obesity and night shifts [15]. Another study [16] shows that even under extreme long-term viewing conditions, none of the assessed LED sources suggested cause for concern for public health.…”

Circular Economy Aspects Regarding LED Lighting Retrofit—from Case Studies to Vision

2018

The lighting industry is still a linear economy, despite the extensive use of light-emitting diode (LED) and the ban of incandescent/halogen lamps, claiming to be greener and more human centered. Light-emitting diode has changed radically the whole lighting industry with an increased luminaire efficacy more than four times higher compared with fluorescent lamps and their new opportunities for modern control systems. In the years to come, millions of fluorescent luminaires will become waste and will be replaced by LED luminaires. According to the Cost European Cooperation in Science & Technology Program the next step will be from sustainability to regenerative (enabling social and ecological systems to maintain a healthy state and to evolve) and to get there, circular economy is essential. In order to reduce even further the carbon footprint, the retrofit of existing luminaires and additional modern control systems should be the solution. Circular economy aspects for the lighting area were identified using the university adopted lighting retrofit solutions as case studies. For an LED retrofitted recessed luminaire 4 × T8 18 W studies showed a major installed power reduction, a good lighting distribution, but also revealed some problems: the retrofit luminaire has no certification, necessity of qualified personnel, high labor costs, etc. A major issue is the fact that luminaire design did not take into consideration circular economy aspects like the possibility of future retrofit solutions. It is important that from now on a different approach should be foreseen for the LED luminaire design. There is a section about vision, which plays an important role in preparing new luminaire generations with circular economy in mind.

Does artificial light-at-night exposure contribute to the worldwide obesity pandemic?

Abstract: This study is the first population-level study that confirms the results of laboratory research and cohort studies in which ALAN was found to be a contributing factor to excessive body mass in humans.
