Title Lighting the graveyard shift: The influence of a daylight-simulating skylight on the task performance and mood of night-shift workers
Bibliographic information 1997, Vol.29, No.3, p.105-118. Illus. 35 ref.
Abstract This experiment was designed to establish whether lighting provided by a daylight-simulating skylight could be used to enhance the task performance and mood of night-shift workers. Subjects performed a series of cognitive tasks, gave subjective ratings of their mood and had their core temperature measured six times during each shift, for three successive nights, under the same lighting condition. Four lighting conditions were experienced. The high, increasing and decreasing illuminance conditions produced higher core body temperatures and greater subjective arousal than did the low illuminance condition. The high- and decreasing-illuminance conditions improved the performance of complex cognitive tasks relative to the low and increasing illuminance conditions. There was no difference between the lighting conditions for the performance of simple cognitive tasks. The high illuminance condition led to a greater delay in going to bed following the shift than did the low-illuminance condition.
