Blue light and circadian clock

It was assumed that blue light from mobile phones at night disrupts the circadian circle, because it leads to a melatonin suppression, and thereby disrupts sleep. However, new research finds no conclusive evidence that it is particularly the blue light that is responsible for sleep disruptions, but rather that the main effect stems to a large degree from flickering light.
