Not Sleeping Well? Go Get More Daylight!

Washington, D.C. – September 30, 2014 – The International Window Film Association (IWFA) notes that a recent controlled study of office workers found that the amount of daylight exposure they received had an important impact on their overall health and sleep patterns.

The study concluded that office workers in windowless environments reported limitations due to physical problems and vitality, as well as poorer overall sleep quality and disturbances. In comparison, workers with windows at the workplace had more light exposure during the workweek resulting in more productivity and longer sleep duration as measured by the research team.

The study, which was published in the Journal of Clinical Sleep Medicine, suggests that architectural design of office environments should place more emphasis on sufficient daylight exposure for workers to support their productivity, health and well-being. The study can be found here: Sleep Study.

“Letting in abundant daylight into offices is very much desired, but may present a real problem for those who don’t want to have harmful UV rays, glare and hotspots negatively impacting their workers’ comfort and health,” said Darrell Smith, executive director of the IWFA. “Despite the myths that window film makes indoor spaces dark, window films can let in ample natural sunlight without the downside risks of harmful UV rays that can damage the skin and eyes, cause hotspots, glare and lead to higher energy costs,” he added.

Window films give the exterior of buildings and homes a uniform, modern look, without all the clutter of shades and curtains haphazardly open or closed. Unlike window attachments, they also require no human or mechanical intervention, as window film is a passive product that performs 24 x 7. Professionally installed window films can also reduce glare by more than 50 percent, while allowing 30 to 80 percent of visible light in and blocking up to 99 percent the sun’s UV rays.
