New iPhone update can help you sleep like a baby.


We all know that checking our iPhone late at night can interrupt our sleep—and it’s not just the stress of that latest email chain. It’s the blue light from the screen itself messing with our circadian rhythms, making it tough to get a good night’s sleep.


Apple’s latest iOS update helps solve that problem. By tapping into the clock and the GPS on your iPhone or iPad, your device will automatically shift from blue light to a warm glow come sunset. By the time you’re ready for bed, your circadian rhythms should be yawning right along with you.

To turn it on, simply go to Settings/Display & Brightness/Night Shift. You also need to make sure both Location Services and Setting Time Zone is enabled. Once that’s done, you’re golden.
