  Title Nocturnal light pollution and underexposure to daytime sunlight: Complementary mechanisms of circadian disruption and related diseases Type Journal Article
  Year 2015 Publication (up) Chronobiology International Abbreviated Journal Chronobiol Int  
  Volume Issue Pages 1-20  
  Keywords Human Health; Artificial light at night; cancer; circadian time structure; development and disruption; melatonin; sleep/wake cycle disturbance; sunlight; vitamin D; vitamin D deficiency; circadian time structure; circadian rhythm; desynchrony  
  Abstract Routine exposure to artificial light at night (ALAN) in work, home, and community settings is linked with increased risk of breast and prostate cancer (BC, PC) in normally sighted women and men, the hypothesized biological rhythm mechanisms being frequent nocturnal melatonin synthesis suppression, circadian time structure (CTS) desynchronization, and sleep/wake cycle disruption with sleep deprivation. ALAN-induced perturbation of the CTS melatonin synchronizer signal is communicated maternally at the very onset of life and after birth via breast or artificial formula feedings. Nighttime use of personal computers, mobile phones, electronic tablets, televisions, and the like – now epidemic in adolescents and adults and highly prevalent in pre-school and school-aged children – is a new source of ALAN. However, ALAN exposure occurs concomitantly with almost complete absence of daytime sunlight, whose blue-violet (446-484 nm lambda) spectrum synchronizes the CTS and whose UV-B (290-315 nm lambda) spectrum stimulates vitamin D synthesis. Under natural conditions and clear skies, day/night and annual cycles of UV-B irradiation drive corresponding periodicities in vitamin D synthesis and numerous bioprocesses regulated by active metabolites augment and strengthen the biological time structure. Vitamin D insufficiency and deficiency are widespread in children and adults in developed and developing countries as a consequence of inadequate sunlight exposure. Past epidemiologic studies have focused either on exposure to too little daytime UV-B or too much ALAN, respectively, on vitamin D deficiency/insufficiency or melatonin suppression in relation to risk of cancer and other, e.g., psychiatric, hypertensive, cardiac, and vascular, so-called, diseases of civilization. The observed elevated incidence of medical conditions the two are alleged to influence through many complementary bioprocesses of cells, tissues, and organs led us to examine effects of the totality of the artificial light environment in which humans reside today. Never have chronobiologic or epidemiologic investigations comprehensively researched the potentially deleterious consequences of the combination of suppressed vitamin D plus melatonin synthesis due to life in today's man-made artificial light environment, which in our opinion is long overdue.

  Title Shot in the Dark: Nocturnal Philosophy and Night Photography Type Book Chapter
  Year 2018 Publication (up) Critical Distance in Documentary Media Abbreviated Journal  
  Volume Issue Pages 45-67  
  Keywords Society; Art  
  Abstract This chapter examines the neglected practice of night photography, and how it critically addresses the environmental, sociohistorical, and urban issues in recent series by Christina Seely, Bruno Lessard, Michel Huneault, and Jeanine Michna-Bales. Drawing on Jacques Derrida, Emmanuel Levinas, and the emerging field of night studies to create a nocturnal philosophy—a dark photology—with which to frame the multifaceted issues at the heart of the series, the author examines the value that these photographic artists place upon night to document light pollution around the world, ongoing urban transformations in China, an environmental catastrophe and its aftermath in Québec, and the landscape of the Underground Railroad in the United States. These four series demonstrate how night photography offers a unique critical perspective on some of the most pressing problems of our age, and how these artists distance themselves from the predominantly diurnal register of documentary media.
