E-Readers vs. Books for Sleep: What the Science Says

Reading before bed is a long-standing tradition for winding down. While many assume e-readers fall somewhere between smartphones and traditional books in terms of sleep disruption, recent insights suggest they may actually be better for sleep than physical books.

The Shifting Science on E-Readers and Sleep

A decade ago, a study raised concerns about e-readers, finding they could lower melatonin levels and disrupt circadian rhythms, making it harder to fall asleep. But, these findings were quickly disputed by other sleep experts who criticized the study’s methodology, arguing it didn’t accurately reflect real-world usage.

Now, Dr. Katherine Sharkey, a sleep researcher at Wake Forest School of Medicine, offers a new perspective. In a recent interview with the New York Times’ Wirecutter, she explained that e-readers may be easier on the brain than traditional books and it has little to do with light exposure.

Why E-Readers Might Promote Sleep

Dr. Sharkey’s reasoning centers on the reduced physical and mental effort required to use an e-reader. “You’re not under the light, you’re not turning pages, you’re not holding the heavier book. You’re just tapping to turn a page,” she stated. The simplicity of tapping to advance a page requires less cognitive and physical exertion than physically turning pages and holding a book open.

E-readers are also significantly lighter than most books, even paperbacks. This reduced weight and the ease of one-handed operation contribute to a more relaxed experience, potentially easing the brain into sleep mode.

Personal Experience and the Kobo Clara Colour

The ease of use extends to devices like the Kobo Clara Colour. Compared to the grip and page-turning mechanics of a traditional book, an e-reader can be held comfortably in one hand with minimal effort. This lighter load can be beneficial for those seeking to unwind before bed.

Individual Preference and the Power of Reading

While the science suggests a potential advantage for e-readers, individual preferences still play a significant role. The goal is to find a reading method that promotes relaxation and prepares the mind for sleep. As highlighted in the Wirecutter piece, for some, a Kindle—or any e-reader—can be the key to overcoming insomnia and achieving restful sleep.
