Study Concludes Workers in Windowless Offices Lose 46 Minutes of Sleep Each Night

Craig DiLouie August 28, 2014

Research by an interdisciplinary team at the University of Illinois found that office workers in windowed spaces scored better on common self-report health and sleep surveys, averaging 46 minutes of sleep per night (measured by sleep monitor) compared to workers without windows.

More evidence that appropriately designed lighting may be preventive medicine? Maybe so, though it begs the question of how well they isolated light as a factor as opposed to human factors such as income, job security, etc.

The study concludes: “We suggest that architectural design of office environments should place more emphasis on sufficient daylight exposure of the workers in order to promote office workers’ health and well-being.”
