Apple's Night Shift mode

     Apple has incorporated a new feature in their iOS update called Night Shift that could help people sleep better. This feature will use the device's clock and geolocation to determine what time the sun sets and will automatically shift the phone's display color to the warmer and redder until the following morning.
     This feature is really helpful because disturbing circadian rhythms can increase a person's chances of developing a variety of serious diseases, and also it helps travelers get over het lag. Although all light, not just blue light increases alertness and have an effect on the body clock and that this feature will not eliminate the problems caused by using electronic devices after sundown, it helps reduce its impact.
