Office lighting and personal light exposures in two seasons: Impact on sleep and mood
Abstract
Lighting design for office buildings has focused largely on providing sufficient light for visual performance, minimal glare, good colour rendering and energy conservation. Little attention has been given to understanding how light affects the non-visual systems, including circadian regulation that affects sleep and mood. Circadian light–dark and activity–rest patterns of individuals working in a building designed to provide daylight availability in the space were obtained in winter and summer. Measures of objective and subjective sleep and self-reports of mood were also obtained from participants. Results show a significant increase in light exposure during summer. Sleep quantity and quality were also significantly higher in summer than in winter. Strategies to increase circadian light exposures in buildings should be a consideration in architectural design.

“Does daylight and/or mixed daylight/electric light conditions during the day mediate better sleep quality at night, and if yes, how? There is some evidence that indoor and/or outdoor bright light exposure during the day leads to longer sleep duration and increases sleep quality as was shown in laboratory and field stu…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
