According to a University of Manchester study, your smartphone’s night mode might not let you fall asleep as previously thought. The warmer light transmitted may actually keep you awake for longer than with night mode disabled.

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?
