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.

Why it stays in the corpus

Retain as the landmark workplace daylight-sleep field study.
