Impact of Windows and Daylight Exposure on Overall Health and Sleep Quality of Office Workers

What the study found

Workers with more window/daylight exposure reported better sleep and wellbeing and had longer sleep duration in actigraphy analyses.

Limitations

Small non-randomized sample; groups may differ in more than daylight; daylight dose not isolated.

Neurodesign interpretation

The strongest design implication is downstream: a workplace feature can change what happens in the bedroom hours later.

Possible design implications

Place regularly occupied work areas where occupants can receive meaningful daytime light exposure.
