Improving your sleep hygiene is a key part of getting quality zzz’s, and reading before bed can be a great part of your bedtime routine. According to Dr. Michael Mosley, author of Fast Asleep, if you’re trying to improve your slumber, “using your smartphone in bed is a very bad idea, as is having a television in the bedroom.” Instead, he advises disconnecting from tech and winding down with a calming activity, such as a reading a book or listening to music.
