Current research shows, that light directly influences the course of the inner biological rhythm. Light synchronizes the biological clock by controlling the concentration of various hormones in the human body. A well-known example is the discharge of melatonine due to increased blue spectral parts in daylight. Light affects the quality of sleep, general performance and even the phenomenon Season Affected Disorder (SAD).
