DARIEN, Ill. (CBS St. Louis) – According to a recent study, workers in offices with windows get a better night’s sleep than employees who don’t have them.

The study also found that workers located in offices with windows are more physically active and have a higher quality of life, according to HealthDay.

A reported 49 day-shift office employees were asked to participate in the study, 22 of whom worked in offices with windows and 27 who worked without them.

Researchers, including study co-author Ivy Cheung of Northwestern University in Chicago, found that those in offices without windows received 173 percent more light exposure during work hours.

They also reportedly slept an average of 46 more minutes at night.

“The extent to which daylight exposure impacts office workers is remarkable,”  Cheung, a doctoral candidate in the inter-departmental neuroscience program at Northwestern University, was quoted as saying in a press release.

Researchers added that the design of a building should be taken into consideration, in regards to how employees are exposed to daylight.

“Day-shift office workers’ quality of life and sleep may be improved via emphasis on light exposure and lighting levels in current offices, as well as in the design of future offices,” Cheung noted in the release.

This study did not establish a cause-and-effect relationship, HealthDay noted, and all data gathered is said to be considered preliminary.

The findings of the study were all the same presented last week at the annual meeting of the Associated Professional Sleep Societies.
