The lights that are used in experiments where you perturb people's circadian rhythm a. la The Geometry of Biological Time https://lab.rockefeller.edu/cohenje/assets/file/098CohenBook... (review) are really bright, as our the lights used for treating SAD. I always thought the fear over screens was the kind of bogus thing people wanted to believe in.

Orange light synced with the daybreak and sunrise made my life better. So something is odd with this scientific research. Any explanations?

Fun fact: After sunset, the color temperature from moonlight is a neutral 4000K. The obsession with blue light came out of a hypothesis based on an analysis of proteins found in the eye, not on actual research of their effect. Further research showed that mammals circadian rhythms are likely more affected by yellow light, than blue light: https://www.manchester.ac.uk/about/news/researchers-discover...
