Ok I gave in and looked at another two:
"Exposure to Room Light before Bedtime Suppresses Melatonin Onset and Shortens Melatonin Duration in Humans":
* nothing about blue light
* didn't measure actual effects, just melatonin levels.
"The human circadian system adapts to prior photic history":
* nothing about blue light
* didn't measure actual effects, just melatonin levels.
So zero out of three studies in your link I looked at support the claims. As you posted these studies: Can you point me to a single study from that list that supports your claims?
- secabeen 7y agoInteresting. These studies seem to be looking at physical or chemical data. Is it possible that the patterns that people see with evening light are largely mental? Until recently, most artificial light sources used in the home were in the range of 2000K. That could have developed in most people a connection between those color temperatures and sleepyness; one that would not necessarily show up in quantifiable measures like melatonin levels. Of course, that would need to be studied, and would be a more challenging study, but I think you could probably do it.
