> There is conclusive evidence that blue light does not affect sleep in any way as large as people expect. We're talking about 1 minute on average change in sleep duration. Sleep duration and sleep quality are different. Blue light definitely affects sleep quality, as your own link shows multiple studies that found this result. The causal association of blue light and sleep quality is pretty solid. |
