Our life and work style are formed in the condition of daylight cycle. Many aspects of human physiology and behaviour are dominated by24-hour rhythms that have a major impact on our health and well-being. They control sleep/wake cycles, alertness and performance patterns, core body temperature rhythms, as well as the production of the hormones melationin and cortisol (Pechacek et al.,2008). An appropriate light signal during the day and darkness at night are therefore critical in maintaining key aspects of our overall health (Circadian House, 2013).
EWINDOW create a stronge daylight-like evironment, and it can synchronize the lighting ambient to the sun in 24 hours. It correspond with the natural daylight rhythms, means it correspond with our circadian system.
