In our last post we looked at how spending time on smartphones, tablets, and other screens at night can prevent you from falling asleep (or getting enough sleep). In this post, we'll review some of the ways you can tweak your screen time to get to sleep sooner and be better rested the next day. And, as you'll see, you don't necessarily need to give up your electronic reading time before bed.
As noted in our previous post, computer, phone, and tablet screens can interfere with our sleep patterns because they emit light in the blue wavelength, which our brains associate with daylight, and with wakefulness (certain e-reader screens don't have this problem). What if you could adjust the wavelength to make it more conducive to sleep?
