You've probably heard a lot about Night Shift, the new feature in iOS 9.3 that adjusts the color temperature of your iOS device display after sunset to make the harsh, usually bluish light less stressful on your eyes. The result? You may find that you fall asleep faster with Night Shift enabled, as studies have shown that using an iPad or iPhone at night can cause some people to have problems getting to sleep. Here's how to enable it.

Launch the Settings app, then scroll down to Display & Brightness and tap on it. You'll see a new item for Night Shift, which is turned off by default. Tap on that Night Shift button to open up a control panel for the new feature.

To enable Night Shift, tap the Scheduled button so that it turns green, designating that it is on. Normally, Night Shift will show a scheduled time, from 10 PM to 7 AM by default. During my testing of iOS 9.3, I found that I really like to have Night Shift turn on at sunset and go off at sunrise. 

To make that change, tap on the "From / To" button, and you can either select "Sunset to Sunrise" or a Custom Schedule between certain hours. 

Other controls in the control panel allow you to manually turn on Night Shift with a tap, and to make the color less warm (more bluish) or more warm (more orangish). I found that I needed to move the color temperature toward the less warm end of the spectrum so that the display didn't look too "orangey". 

Update: We forgot to tell you that you can easily enable or disable Night Shift from the iOS Control Center. Simply swipe up from the bottom of your home screen to expose Control Center, then tap on the center button in the lower row of buttons to turn Night Shift on or off immediately. 

Give Night Shift a try - if you're anything like me, you'll love it!
