Readers of print books remember more than readers of e-books do, according to a study that was presented in Italy in 2014. In an earlier study, print readers also scored higher in other areas, such as immersion in the book, and understanding of the narrative. Scientists believe this effect is related to the tactile sensation of holding a book in your hands.

One recent study in the U.S., Slovakia, Japan, and Germany showed that 92 percent of participants preferred actual books that they can hold and touch and leaf through whenever they please. People highlighted fewer distractions and less eye strain as a couple of the reasons why they prefer printed materials, but other explanations were related to how books make them feel.

When you’re winding down for the night, reading from a screen or scrolling through a social media app on your phone are bad ideas. Study after study has shown that the blue light from your screen can toy with your melatonin levels and circadian cycles, making it harder for you to fall asleep and making you feel groggier when you wake up. In general, though, the engagement and brain activity that come with reading can help you drift off to sleep when you’re having trouble. So if you’re hoping to get a good night’s rest, stick with print.
