In this tech-addicted world, it's not uncommon to sleep with your phone next to you in bed or under your pillow, in case you need to grab it in a fire/use it as a vibrating alarm/check to see who RTed your cutting witticism re: TSwift's Grammy win at 2 a.m. It turns out, however, that this is a Bad Idea, as proven by a recent tweet from the NYPD showing a series of photos from cell phone that exploded under a pillow. Here's some nightmare fuel:

Let's take a closer look, shall we?

It's not super common, but it turns out that covering a phone with fabric from, say, your pillow and sheets could cause it to overheat, potentially leading it to explode or set your bedding on fire. This very phenomenon happened to a teen in Texas a few years ago—her Samsung Galaxy S4 lit aflame, which was very unpleasant.

It's unclear whether the exploded phone photos are new or just part of a PSA from the NYPD, since at least some of them look similar to the aftermath of the aforementioned Texas phonesplosion, but still, scary! And there are plenty of other reasons to keep your phone out of your bed while you sleep. LED screens mess with your circadian rhythms, for one thing, and while cell phones don't give off a ton of radiation, long-term effects of smart phone use haven't really been seen yet, so you might as well limit your body's phone exposure when you don't really need it.
