About Night Shift in iOS 9.3

In iOS 9.3, Apple has added a new feature, called Night Shift, which reduces the amount of blue light emitted by your device’s screen. Many studies have indicated that exposure to blue light tricks your brain into thinking that it’s daytime, possibly both causing a variety of health problems and making it harder to fall asleep—see this Harvard Health Letter for more.

A new button in Control Center lets you manually enable Night Shift, but if you visit Settings > Display & Brightness > Night Shift, you can automate when Night Shift turns on and off, and adjust the intensity of the effect. You can enter a set time, or, if you have Location Services enabled, you can set Night Shift to turn on at sunset and back off again at sunrise.

Note that Night Shift isn’t available on all devices that can run iOS 9.3. It requires an iPhone 5s or better, an iPad Pro, iPad Air or later, an iPad mini 2 or later, or a sixth-generation iPod touch.
