Abstract

Our study is an attempt of partial replication of the study on the effects of monochromatic lights from Sahin and Figueiro (2013). We conducted a two-way crossover comparison between the effects of two Light Emitting Diodes (LED) Monochromatic Lights (Red, Blue) administered at 40lx. In the first part (Part I) we explored the possibility of an alerting effect of light comparing basal morning alertness levels, post prandial alertness and post light exposure. According to previous results by the authors (Sahin and Figueiro, 2013) In the second part (Part II) we were partially replicating the study by Sahin and Figueiro (2013). Adopting the same light technology and specifications, alerting effect of light were evaluated by means of repeated EEG measurements of alertness. Our study showed that there is no effect of Monochromatic Light exposure on subjective and objective measure of alertness. Results observed in the analysis of EEG signal highlight a possible role of subcortical regions responsible for arousal regulation that are influenced by exposure to lights of short wavelength. These effects have been found during light exposure; but our results support the possibility that these alerting effects can influence EEG activity even after Monochromatic
