I attended a Human Centric Lighting (HCL) conference in Oslo last week. It was a nice recap as I have done research into the physiological effects of light on health. The speakers included Mariana Fugeiro and Mark Rea from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute in New York. They are both well known researchers in the field of light and health. Their studies have shown that Human Centric Lighting has a significant influence on our health and well-being.
