Reading a book before bed can improve sleep quality but it depends on what you read it on: A 2014 study found people using a light-emitting device took nearly 10 minutes longer to fall asleep than with a printed book

Engaging with printed books before sleeping can significantly enhance sleep quality for numerous individuals. A recent study highlighted that those who read physical books reported improved rest. In contrast, using devices with light-emitting screens, such as iPads, can prolong the time it takes to fall asleep, as these screens hinder melatonin production, a vital hormone for regulating sleep. Thus, opting for printed materials before bed can be beneficial.
