Why Apple's Night Shift On iOS 9.3 Will Help You Sleep Better

Apple just introduced a cool new feature with iOS 9.3, Night Shift. This feature shifts the color spectrum of your iPhone or iPad display at night, to warmer tones that mimic the colors of the sun. So how does this help?

Years of scientific research has proven that exposure to blue light has a noticeable effect on sleep, which has been linked to an increased risk of cancer, obesity, and diabetes.

Blue light is naturally abundant and great during the day, providing the ability to boost attention, reaction time, and mood. Counteractively, exposure at night will throw your sleeping cycle out of whack. A joint study concluded that "the use of these devices before bedtime prolongs the time it takes to fall asleep, delays the circadian clock, suppresses levels of the sleep-promoting hormone melatonin, reduces the amount and delays the timing of REM sleep, and reduces alertness the following morning."

With Apple’s Night Shift feature, Blue Light Reduction is enabled in the Display and Brightness settings. The default setting shifts from sunrise to sunset, but you can set it to fit your own schedule if you prefer.

While this feature will make a difference in your sleep quality, there is no better favor you can do for yourself than to disconnect from your devices well before bed! But lets be realistic, that’s probably not happening…
