Abstract:
The objective of this study was to compare the effects of bright and dim illumination on sublingual temperature and behavioral measures to determine if illumination treatment can reduce fatigue and enhance human work performance during specific evening and nighttime periods. Lighting levels for work are typically task specified for actual optimal visual stimulation without considering potential biological and behavioral effects of the light stimuli. This research effort investigated the possibility that human performance may be less than optimal under the 50 to 500 lux light environment that is typical of many work station settings and that performance may be improved under bright wide spectrum illumination.
