Biodynamic lighting is an artificial light source that replicates the dynamic variations of daylight and sunlight through a light management system. Up until recent times, it was commonly believed that light was only needed for seeing. However, in 2001, an American scientist, G. C. Brainard discovered a circadian photoreceptor in the retina, which receives a specific quality and quantity of light, and sets the biological clock.* He discovered that light not only provides us with the ability to see, but that light enters the eye via the ‘fourth pathway’, which has a vital non-visual or biological effect on the human body. His studies showed that a certain quantity and quality of light stimulates the biological clock, also known as the circadian rhythm, which regulates hormone levels, particularly melatonin and cortisone, in the body and so plays a vital role in our physical and mental wellbeing.
