According to CNET, Apple’s next iOS update will include a feature that will change the display at night in order to help the user sleep.

The company’s developer site says iOS 9.3, the next version of its mobile software, will include a feature called Night Shift that changes the display to make it “easier on your eyes” before you go to bed.

Study after study after study has shown that light given off by electronics affects our sleep. The main issue is the blue light from LED screens can slow or halt the production of melatonin, the hormone that signals our brain that it’s time for bed.
