"Our circadian system is actually not reacting to small changes in "color". Instead, it is mostly reacting to the "amount" of light. Our eyes are extremely good at distinguishing little shades of color from each other, but this is a different system than the one that drives circadian rhythms."
Is there any data to support this?
- kortex 10y agoOne of the primary drivers of melatonin suppression is the IPRGC [1]. So yes, what seems to be more important than the perceived color is the intensity of light in the 460-480 nm range. Which, if the spectral data in the original post are correct, means that NightShift has a major disadvantage.
