The amount of light that enters an office affects everyone, usually without them knowing.. One joint study from Northwestern Medicine and the University of Illinois at Urbana-Champaign shows that lighting even has an impact on the amount of sleep that workers get later on in the day.

A press release on this study, which appeared in the Journal of Clinical Sleep Medicine this June, describes how the natural light that employees were exposed to during the day had health repercussions later on. More light from windows led to more than 45 minutes extra sleep and a tendency toward exercise.

Dr. Phyllis Zee of Northwestern Medicine said in the statement that exposure to light of all kinds is important, especially during the daylight hours, for mood and stability.

“Workers are a group at risk because they are typically indoors often without access to natural or even artificial bright light for the entire day,” she said. “The study results confirm that light during the natural daylight hours has powerful effects on health.”

The researchers came to this conclusion by monitoring the performances of both workers in spaces that had windows and those in windowless areas. The former received more than 170 percent more light exposure.

Arranging the office furniture so that the light in your office reaches the greatest amount of workers is one way to take advantage of these findings.In addition, you can purchase used workstations that are designed for allowing in light and promoting the feel of a bright office than others.

Do thorough research with a quality office furniture provider to find out which items will work best for your organization.
