Night mode/Night Shift has been a popular feature on iOS and Android for quite some time now. Night mode reduces the supposedly harmful blue light emitted from your phone by shifting the white balance to a warmer tone.
Manufacturers have included night mode as a feature after studies indicated that blue light from phones at night disturbed the circadian rhythm.
However, a recent study published by Dr. Tim Brown at the University of Manchester, is bad news for people staying up late using night mode. According to the study - conducted on mice - blue light is actually more relaxing than reddish-yellow light at an equal, low brightness level.
It then goes on to say that light brightness, not color, is what disrupts your body's natural clock. Dr. Brown's study is a working paper and the effect has not been verified with humans.
However, the underlying logical premise is straightforward: yellow is the colour of daylight, while twilight and night are dark blue. So maybe instead of turning on the night mode tonight, why not just put your phone away?
