Title Effects of bright artificial light on subjective mood of shift work nurses
Bibliographic information Jan. 1997, Vol.35, No.1, p.41-47. Illus. 31 ref.
Abstract The effects of bright artificial light on the subjective mental state of ten female hospital nurses were assessed during two series of five consecutive workshifts: one normal, two night and two evening shifts. The subjects worked under normal lighting conditions (approximately 250 lux) during the first series, and were exposed to artificial light (brighter than 3,000 lux) for a total of 30min during the second series of shifts. Bright light tended to improve eagerness and reduce tension. Several psychological symptoms, such as vigour, eagerness, appetite and impairment, also improved in artificial light during the night shifts, but not during the evening shifts.
