Putting a number on wellness: Why you should care about Melanopic Equivalent Daylight Illuminance (M-EDI)
Ever wondered why you feel more energized on a sunny day or why staring at your phone late at night messes with your sleep? It’s all about how light impacts your body’s internal clock. Since the dawn of time, our bodies cleverly used the rising and setting of the sun to set our daytime and nighttime physiology. Electric lights effectively broke our connection with the sun and this has caused problems with health and wellness. So, more and more frequently, the question “Is my light healthy?” is being asked by the public, architects, lighting designers, and regulatory agencies around the world.
This is where Melanopic Equivalent Daylight Illuminance (m-EDI) comes in—a science term that’s actually really important for your health and well-being.
