Looking at your phone at night is a bad idea. The bight blue light emitted by the screen can make it more difficult to fall asleep and mess with your sleep cycle, which could lead to a whole host of health problems.

But we're realistic. We know that plenty of people still sneak a peek at their email right before they go to bed, or read the news on their phone as they're falling asleep.

If you're reading in a dark room, the iPhone's screen can be too bright, even at its lowest setting.

Good news: There's a way to dim the iPhone's screen even further than the Settings allow. I first learned about it about dimming my iPhone earlier this year when I came across a guide on Medium written by Justin Searls, a programmer, and I use it almost every day.

It involves a few steps, but it's easy to do and will completely change how you use your phone at night.
