  Title A summary of LED lighting impacts on health Type Journal Article
  Year 2015 Publication International Journal of Sustainable Lighting Abbreviated Journal Intl. J. of Sustainable Lighting  
  Volume 1 Issue 1 Pages (up) 5-11  
  Keywords Human health; light and health; LED glare; LED flicker; melatonin supression; LED skin exposure  
  Abstract Lighting can affect the health of people in buildings. This goes beyond the safety aspects of providing enough illumination to see by; lighting affects mood and human circadian rhythms, while poor lighting can cause glare, headaches, eyestrain, aches and pains associated with poor body posture or, in extreme cases, skin conditions and various types of sight loss. These aspects ought to be considered by designers and building owners and occupiers in order to improve the lit environment and use adequate lighting and lighting controls that meet the recommendations of codes and standards. Various types of lighting can have different impacts depending on their spectral, optical and electrical characteristics. This paper discusses potential impacts of LED lighting on human health, and is based on a recent BRE review of research investigating the most typical effects of lighting on human health.

  Title Suppression of melatonin secretion in some blind patients by exposure to bright light Type Journal Article
  Year 1995 Publication The New England Journal of Medicine Abbreviated Journal N Engl J Med  
  Volume 332 Issue 1 Pages (up) 6-11  
  Keywords Human Health; Adolescent; Adult; Aged; Blindness/etiology/*physiopathology; Circadian Rhythm; Female; Humans; *Light; Male; Melatonin/blood/*secretion; Middle Aged; Photic Stimulation; Sleep Initiation and Maintenance Disorders/physiopathology; Visual Perception  
  Abstract BACKGROUND: Complete blindness generally results in the loss of synchronization of circadian rhythms to the 24-hour day and in recurrent insomnia. However, some blind patients maintain circadian entrainment. We undertook this study to determine whether some blind patients' eyes convey sufficient photic information to entrain the hypothalamic circadian pacemaker and suppress melatonin secretion, despite an apparently complete loss of visual function. METHODS: We evaluated the input of light to the circadian pacemaker by testing the ability of bright light to decrease plasma melatonin concentrations in 11 blind patients with no conscious perception of light and in 6 normal subjects. We also evaluated circadian entrainment over time in the blind patients. RESULTS: Plasma melatonin concentrations decreased during exposure to bright light in three sightless patients by an average (+/- SD) of 69 +/- 21 percent and in the normal subjects by an average of 66 +/- 15 percent. When two of these blind patients were tested with their eyes covered during exposure to light, plasma melatonin did not decrease. The three blind patients reported no difficulty sleeping and maintained apparent circadian entrainment to the 24-hour day. Plasma melatonin concentrations did not decrease during exposure to bright light in seven of the remaining blind patients; in the eighth, plasma melatonin was undetectable. These eight patients reported a history of insomnia, and in four the circadian temperature rhythm was not entrained to the 24-hour day. CONCLUSIONS: The visual subsystem that mediates light-induced suppression of melatonin secretion remains functionally intact in some sightless patients. The absence of photic input to the circadian system thus constitutes a distinct form of blindness, associated with periodic insomnia, that afflicts most but not all patients with no conscious perception of light.

  Title Review: The Impact of Light in Buildings on Human Health Type Journal Article
  Year 2010 Publication Indoor and Built Environment Abbreviated Journal Indoor and Built Environment  
  Volume 19 Issue 1 Pages (up) 8-20  
  Keywords Human Health; indoor light; circadian disruption; shift work; oncogenesis; Review  
  Abstract The effects of light on health can be divided into three sections. The first is that of light as radiation. Exposure to the ultraviolet, visible, and infrared radiation produced by light sources can damage both the eye and skin, through both thermal and photochemical mechanisms. Such damage is rare for indoor lighting installations designed for vision but can occur in some situations. The second is light operating through the visual system. Lighting enables us to see but lighting conditions that cause visual discomfort are likely to lead to eyestrain. Anyone who frequently experiences eyestrain is not enjoying the best of health. The lighting conditions that cause visual discomfort in buildings are well known and easily avoided. The third is light operating through the circadian system. This is known to influence sleep patterns and believed to be linked to the development of breast cancer among night shift workers. There is still much to learn about the impact of light on human health but what is known is enough to ensure that the topic requires the attention of all those concerned with the lighting of buildings.

  Title Light Pollution and Its Effect on the Environment Type Journal Article
  Year 2014 Publication International Journal of Fundamental Physical Sciences Abbreviated Journal Intl. J. of Fundamental Phys. Sci.  
  Volume 4 Issue 1 Pages (up) 8-12  
  Keywords Light pollution, human health, animal behaviour, plant growth  
  Abstract Light pollution can cause disturbance to humans as well as animals. The aim of this study is to determine the effect of light pollution on human's health, plants, animals, human body and People’s attitude about light pollution. About 90% of people strongly agreed that excessive lighting has adverse effects on a person's health. At least, 70% of people had difficulty in sleeping because of light pollution. Most of people believed that video Billboards, Spotlights, Car headlights and Street lights are the most important source of light pollution and about 60% of people agree that light pollution can affect animal’s sleep. 60% of people believed that excessive artificial light can attract several kinks of birds and insects. The results of this study indicate that the human health, plants growth and animal behaviour are strongly affected by the light pollution.‎
