15 – 17 Results of several studies suggest that both natural and artificial bright light, particularly in the morning, can improve significantly health outcomes such as depression, agitation, sleep, circadian rest-activity, and seasonal affective disorder. 14 In humans, a direct correlation between the severity level of seasonal affective disorder and exposure to natural light is well documented. Deprivation to light damages monoamine neurons and produces a depressive behavioral phenotype in rats. 10 – 13 Therefore, it is crucial to investigate the effects of daylight as it may provide a profound way to improve office workers' productivity and health as well as the safety of the community they work and live in. Sleep quality is also an important health indicator that may have effects on, and interactions with mood, cognitive performance, and health outcomes such as diabetes and other illnesses. 7 – 9 If windowless environments or lack of daylight affect office workers' sleep quality, there will be subsequent effects not only individually but also on a societal level, leading to more accidents, workplace errors, and decreased productivity. There is much evidence that links insufficient sleep and/ or reduced sleep quality to a range of significant short-term impairments such as memory loss, slower psychomotor reflexes, and diminished attention.
Office workers' physical and mental well-being may be improved via enhanced indoor lighting for those with insufficient daylight in current offices as well as increased emphasis on light exposure in the design of future offices. Study Impact: Office workers with more light exposure at the workplace tended to have longer sleep duration, better sleep quality, more physical activity, and better quality of life compared to office workers with less light exposure at the workplace. While research indicates possible links between light exposure in workplaces and workers' productivity and performance, less is known about the role of workplace light exposure on workers' quality of life and sleep quality. 6 Given that office hours occur during biologically natural daylight hours, we posit that light exposure in the office environment will have effects on sleep, and via sleep and other influences also have effects on physical and mental health.Ĭurrent Knowledge/Study Rationale: Both the amount and timing of light exposure is important for physical and mental health. 5 The timing of light exposure is very influential on these rhythms, and previous research has shown that office environment lighting during work hours can act as a regulator of circadian physiology and behavior, with blue-enriched artificial lighting even competing with natural light as an entrainer. Exposure to light-dark patterns is one of the main environmental cues for circadian rhythms that influence approximately 24-hour biological, mental, and behavioral patterns such as sleep and activity. The daylight factor principle is valid for stable overcast sky conditions only sunny conditions are too dynamic and changing to be considered.Īlthough there are many studies that have explored the relationship between daylighting, psychological well-being, and workers' productivity or school children's performance, 2 – 4 few have addressed the impact of daylight at the workplace on sleep, quality of life, and overall health. A daylight factor is a percentage of indoor illuminance compared to the outdoor illuminance on a horizontal surface. Typically, daylighting recommendations are made in the form of daylight factor levels ranging between 2% to 6% depending on building types and activities. With the increased interest today in green architecture, daylighting is becoming an important design consideration. Since the sick building syndrome of the 1970s and the World Health Organization's Declaration on Occupational Health for All in 1994, 1 occupational health has become a salient issue among health professionals and architects alike.
