Is Night Shift helping you sleep better?

  ...It actually seems like the article buries the lede a bit, because the while study did find that using Night Shift on their phones had no effect on their sleep, it also found that, overall, there was nearly no detectable effect of using your phone before bed on sleep length. They did find a small effect when they controlled for the previous day's sleep, but only in people who had slept well—if you're already exhausted, it doesn't matter whether you use a phone or not before bed. Their conclusion, overall, appears to be that it's the psychological arousal/engagement of the activities you do on your phone that makes it harder to get to sleep, rather than the blue (or any) light.
