Why Reading Before Bed Might Be Your Best Sleep Hack Yet, According to Brain Health Experts

Key Takeaways

• Reading before bed offers a healthier alternative to screens, since blue light from phones and tablets suppresses melatonin—while books, free of notifications and algorithmic novelty, are easier for the brain to disengage from.

• Reading doesn't directly induce sleep, but it reduces the factors that keep us awake: absorbing just enough attention to quiet rumination about the day's events or tomorrow's tasks, helping the body shift from "alert" to "rest" mode.

• The ritual of reading at the same time each night can become a powerful sleep cue on its own—but experts recommend sticking to print books or basic e-ink devices, and choosing calm, low-stakes material over suspenseful or stressful reading.

As someone who often struggles to fall asleep, climbing into bed can feel daunting: I don't want to lie there, tossing and turning, but I don't want to bombard my brain with overstimulating blue light or endless thought ruminations . That's why cracking open a book has become an essential step in my nighttime routine . I've always felt like I doze off more easily and get more restful sleep when I read before bed—and, according to sleep experts, there's science behind why that is.

Why Reading Before Bed Can Help Us Fall Asleep

It might seem obvious, but books present a healthier alternative to screen time before bed. It's well-established that blue light exposure can suppress melatonin , the hormone that rules our sleep-wake cycle. 

"Social media is intentionally designed around novelty, unpredictability, and intermittent rewards, all of which activate attentional and motivational networks that encourage us to keep interacting," says Laura Bojarskaite , PhD, a neuroscientist and postdoctoral researcher at the University of Oslo. "A book is typically slower, more predictable, and free from notifications or endless content, making it much easier for the brain to disengage."

But, even if you completely remove tech from the equation, reading before bed still offers benefits. So many of us struggle to fall asleep at night because we're stuck in our heads—as we lie in bed, we might be reflecting on an event that happened during the day, thinking about our plans for tomorrow, or even obsessing over an embarrassing moment that happened five years ago. 

It's not exactly the book itself offering that reprieve from our inner worlds—it's just the act of reading. "Reading doesn't directly make the brain produce sleep. Instead, it reduces some of the factors that keep us awake," Bojarskaite says. "If you're absorbed in a calm book, you're less likely to replay stressful conversations, think about tomorrow's tasks, or continue seeking stimulation from your phone."

A book gives us something else to focus on and can help us shift gears into relaxation mode, according to Joanna Fong-Isariyawongse , an associate professor of neurology at the University of Pittsburgh who specializes in sleep medicine. Reading "absorbs just enough attention to mute that rumination. It also keeps us calm enough to turn down [our] stress response," she says. "It facilitates autonomic downshift, from 'alert' to 'rest' mode."

Even the ritual of picking up a book before bed can support sleep hygiene, the same way a warm cup of tea or a journaling session can help us shake off the stress of the day. "When it happens at the same time, in the same way, night after night, it becomes a cue: This is when we wind down," Fong-Isariyawongse explains. "Consistency is the key." 

How to Maximize the Benefits of Reading Before Bed

Many of us prefer to read on digital devices, as opposed to traditional books. But reading on a phone or tablet—which emits blue light—can present some of the same distractions and melatonin disruption that social media scrolling does. Instead, a basic e-reader can do the trick: "When in doubt, go old-school," Fong-Isariyawongse suggests. "Print books and basic e-ink devices are still the gold standard for winding down."

It's best to be a little selective about what exactly you read before bed, Bojarskaite says. Try to avoid stressful plotlines or high-impact articles. "If you're reading a suspenseful thriller that keeps your heart racing, a stressful work report, or emotionally upsetting news, you're probably not helping your brain prepare for sleep," she explains. "The ideal bedtime reading is engaging enough to hold your attention, but not so stimulating that it increases emotional or physiological arousal."
