Daylight: Employees in offices with windows slept an average of 46 minutes more per night

A recent study by neuroscientists (American Academy of Sleep Medicine, 2013) suggested that office workers with windows received 173 percent more white light exposure during work hours, and slept an average of 46 minutes more per night. Workers without windows reported poorer scores than their counterparts on quality of life measures related to physical problems and vitality, as well as poorer outcomes on measures of overall sleep quality, sleep efficiency, sleep disturbances and daytime dysfunction.
