Coloured artificial light can regulate our circadian rhythm and provide us with a better sleep quality. But how should the light be combined and interact with daylight? How strong should it be? What colour composition and heat balance are optimal? Could it be thought that the good mix is individual? Researchers are in the process of studying the full potential of circadian rhythm lighting in a pilot study among nursing home residents. (Photo: Colourbox)
Professor Poul Henning Kirkegaard wants a closer understanding of how coloured circadian rhythm lighting and its interaction with the surroundings and daylight can be incorporated into the architecture. He hopes that in the future we will be able to live in buildings that provide better sleep quality. (Photo: Anders Trærup)
