Screen Time and Teen Sleep: What a New Study Found

One more video. One more message. A quick check that turns into twenty minutes.

For a teenager finishing the day, a phone can keep the conversation going long after the rest of the house has settled down. For parents, that raises a familiar question: what should bedtime look like when so much of a child’s social life happens on a screen?

A study published in the Journal of Adolescent Health on November 6, 2026, examined 218 teenagers ages 13–18 across the United States. According to its published abstract, researchers monitored smartphone activity for an average of 17.5 days and compared it with survey-reported sleep.

Greater smartphone use was associated with later sleep onset, shorter sleep, more variation between scheduled-day and free-day sleep timing, and more catch-up sleep on free nights. The strongest associations involved evening, nighttime and social media use. Several links with sleep timing and duration were stronger among female participants.

Phone use was recorded automatically, but sleep was self-reported. These associations do not prove that smartphone use caused the sleep problems. The study did not test bedtime reading or the Book Buddy.

For families thinking about screen time and teen sleep, a useful place to begin is the evening routine. What needs to happen before bed, and where does the phone fit?

The American Academy of Pediatrics recommends putting screens away at least an hour before bedtime and charging devices outside the bedroom. Discuss a stopping time with your teen while everyone is awake and reasonably relaxed. Ask what they usually do on their phone at night. Homework, talking with friends and watching videos may each need a different place in the evening.

Make the agreement specific. Choose a charging spot. Decide when schoolwork needs to wrap up. If your teen uses a phone as an alarm, consider a separate alarm clock, an option included in the AAP’s teen sleep guidance. That guidance also recommends 8–10 hours of sleep per night and a relaxing bedtime routine.

Give your teen a say in what fills that quieter time. They might choose a printed book, a journal or a shower. Let them choose a paperback they actually want to read. Ask what interests them, browse a bookstore together or let them lead the next library visit.

You can join in, too. Put your own phone on the charger and pick up something you have been meaning to read. Sitting together with separate books can be its own family ritual, even when nobody feels like talking.

At Read To Me, we love the idea of giving stories a regular place at the end of the day. For families with younger children, that might mean choosing a picture book after pajamas and teeth brushing, then settling into the same favorite chair.

Let your child turn the pages. Enjoy the voice they insist you use for the bear. Leave room for the question that has very little to do with the story. Those details are part of what makes the routine yours.

When a loved one cannot be there, a recorded story can still be part of that reading time.

The Recordable Book Buddy attaches to the back cover of virtually any children’s picture book. A parent, grandparent or other loved one records the story page by page, and the child presses the matching buttons to listen while following the physical pages. It creates a personalized read along experience with no apps, no screens and no Wi-Fi.

A parent working evenings can record the story they usually read together. A grandparent can leave a favorite book with their own voice inside it. Add a familiar greeting, a silly character voice or the same goodnight you always say.

The Recordable Book Buddy is available for under $30, in over 150 independent bookstores and online at RecordableBookBuddy.com.

Start with one evening habit your family wants to make room for. Give it a time, a place and something to look forward to. A favorite story is a lovely place to begin.

Your Voice. Their Favorite Story.
