We do not achieve enough natural daylight in our workplace which in turn has negative effects on our productivity and wellbeing.

A new study titled, “Impact of Workplace Daylight Exposure on Sleep, Physical Activity, and Quality of Life,” concludes that there is a strong relationship between workplace daylight exposure and office workers’ sleep, activity and quality of life. The research abstract was published recently in an online supplement of the journal SLEEP.

Disruptions of circadian rhythms is directly linked to sleep disorders. Irregular circadian rhythms have also been associated with obesity, diabetes, depression, bipolar disorder and seasonal affective disorder (SAD).

If you are currently working in a windowless environment—or suffer from seasonal affective disorder (SAD) in the wintertime—you can improve your circadian rhythms by adjusting the architectural space of your office.
