Apple's new operating system has a setting that may help you get to sleep faster. It's called Night Shift.
It was released as part of Apple's iOS 9.3 mobile operating system update.
Night Shift works by automatically changing the settings of an iPhone or iPad screen to warmer colors, decreasing the amount of blue light. Blue light can disrupt the natural production of melatonin, a sleep hormone.
Google is producing a similar setting mode for Android devices.
