Sunlight has an enormous influence on the human organism; a fact that scientists have been investigating increasingly for some years now. The sun's light determines the circadian rhythm that many of our bodily functions run by. For instance our sleeping and waking rhythm, body temperature, hormone levels, respiration and circulatory system. Human Centric Lighting (HCL) was developed to recreate the natural influence of sunlight inside your rooms. HCL simulates the type and intensity of the sun's light, adjusting it automatically as the day progresses, so you enjoy pleasant, natural light all day long. That means higher performance at the workplace and palpable wellbeing in the evening.
