Physiological Effect of Partial Spectrum Lighting on the Human

Abstract

Light could be the most important environmental input, after food, in controlling bodily functions. The extent of this control on humans has become a recent topic of investigation. Investigation of the effects of various frequencies of illumination is a topic relatively unexplored through endocrinology or by examining physiological effects in humans. This research investigates the effect of partial spectrum lighting on the psychomotor performance of nine subjects. The physiological effects as represented through psychomotor performance was determined by measurements taken on grip strength, dexterity, and reaction time. From the results there was no basis on which to reject the null hypothesis. Therefore, no significant psychomotor differences were found between the three light sources tested.
