Abstract
Studies of illumination suggest possibility of colorlights for adjusting our mind and body to suit desired activities.To examine if similar effects can be obtained by modulatingrelative contents of light color, biological effects of color-glasswearing during early-morning drive for commuting werestudied. Compared with clear glasses, blue glasses increased lowfrequency (0.04-0.15 Hz) power and deceleration capacity anddecreased respiration frequency during driving, while green,orange, and pink glasses made no significant difference fromclear glasses. None of the color glasses showed significantdifference in the performance to psychomotor vigilance testperformed at the beginning and the end of work at job place orin the autonomic functions during sleep of that night. Anincrease in the content of blue-wavelength light by blue glassesduring morning drive may attenuate sympathetic function, butit has no significant after-effect on daytime behavioral alertnessor nighttime autonomic functions.
