Title Perspective: The Long-Term Effects of Light Exposure on Establishment of Newborn Circadian Rhythm Type Journal Article
Year 2018 Publication Journal of Clinical Sleep Medicine Abbreviated Journal Jcsm
Volume 14 Issue 10 Pages 1829-1830
Keywords (up) Commentary; Human Health
Abstract Development of newborns continues postnatally. Evidence has accumulated on the early life programming effects of light exposure on the maturing visual axis and the developing circadian rhythm. Consideration of the effects of light at night and insufficient light during the day should occur when giving anticipatory guidance in the care of newborn infants. Long-term health consequences of light imprinting may occur with inappropriate light-dark environments during the newborn period.

Title Gedanken zu Licht und Schlaf [Thoughts about Light and Sleep] Type Journal Article
Year 2019 Publication Praxis Abbreviated Journal Praxis (Bern 1994)
Volume 108 Issue 2 Pages 139-143
Keywords (up) Commentary; Human Health
Abstract Many aspects of health and disease are mainly determined by the constant change between light and darkness during a solar day. The resulting physiological rhythms correspond to the circadian rhythm, which was one of the most central drivers in the evolution of humans. However, over the last 20-30 years, these natural rhythms of the change of light and darkness are being increasingly ignored by modern societies. It is well known that these rhythms are modulators of many physiological pathways and any desynchronization or misalignment will activate different pathophysiological pathways, which contribute to the risk of chronic diseases. Light pollution by widespread illumination of our environment and the night sky and uncontrolled man-made use of any light source plays a key role in the pathogenesis of sleep disturbances. Blue light exposure in the evening from any artificial light source (especially from electronic device screens) is of special relevance in this context. In this article a few key facts concerning light, sleep and diseases are presented. We should by all means account for the effects of light and darkness and stop any further light pollution.

Unser Leben wird durch die sich rhythmisch abwechselnde Helligkeit und Dunkelheit während eines «Solartages» bestimmt, was die Grundlage für den zirkadianen Rhythmus darstellt. Dies war Millionen von Jahren so, und erst in den vergangenen 20–30 Jahren wird diese Rhythmik infolge einer ubiquitären Verwendung von Licht zunehmend ignoriert. Die zirkadiane Rhythmik stellt allerdings eine der zentralsten Determinanten für Gesundheit und Krankheit dar, und man weiss, dass eine Abweichung vom bzw. Desynchronisation des normalen Rhythmus ein hohes pathophysiologisches Potenzial hat und in der Pathogenese der meisten chronischen Erkrankungen eine zentrale Rolle spielt. Die exzessive Beleuchtung der Umgebung und des Nachthimmels wird als Lichtverschmutzung oder «Light Pollution» bezeichnet, die sich unter anderem auch in Schlafstörungen manifestiert. Dabei darf im Besonderen das blaue Licht aus künstlichen Lichtquellen und Bildschirmen am Abend bei der Entstehung von Schlafstörungen nicht ausser Betracht gelassen werden. In diesem Artikel werden einige Aspekte zum Thema Licht, Schlaf und Gesundheit in Erinnerung gerufen und praxisrelevante Zusammenhänge aufgezeigt. Eine Kontrolle der Lichtverschmutzung ist dringend angezeigt.

Title Global rise of potential health hazards caused by blue light-induced circadian disruption in modern aging societies Type Journal Article
Year 2017 Publication NPJ Aging and Mechanisms of Disease Abbreviated Journal NPJ Aging Mech Dis
Volume 3 Issue Pages 9
Keywords (up) Commentary; Human Health
Abstract Mammals receive light information through the eyes, which perform two major functions: image forming vision to see objects and non-image forming adaptation of physiology and behavior to light. Cone and rod photoreceptors form images and send the information via retinal ganglion cells to the brain for image reconstruction. In contrast, nonimage-forming photoresponses vary widely from adjustment of pupil diameter to adaptation of the circadian clock. nonimage-forming responses are mediated by retinal ganglion cells expressing the photopigment melanopsin. Melanopsin-expressing cells constitute 1-2% of retinal ganglion cells in the adult mammalian retina, are intrinsically photosensitive, and integrate photic information from rods and cones to control nonimage-forming adaptation. Action spectra of ipRGCs and of melanopsin photopigment peak around 480 nm blue light. Understanding melanopsin function lets us recognize considerable physiological effects of blue light, which is increasingly important in our modern society that uses light-emitting diode. Misalignment of circadian rhythmicity is observed in numerous conditions, including aging, and is thought to be involved in the development of age-related disorders, such as depression, diabetes, hypertension, obesity, and cancer. The appropriate regulation of circadian rhythmicity by proper lighting is therefore essential. This perspective introduces the potential risks of excessive blue light for human health through circadian rhythm disruption and sleep deprivation. Knowing the positive and negative aspects, this study claims the importance of being exposed to light at optimal times and intensities during the day, based on the concept of the circadian clock, ultimately to improve quality of life to have a healthy and longer life.
