New Study Reveals How Screen Time Affects Preteen Sleep

The following is excerpted from an online article posted by MedicalXpress.

The US Surgeon General recently recommended a warning label for social media platforms due to concerns about their impact on youth mental health. The Surgeon General’s Advisory on Social Media and Youth Mental Health highlighted potential links between social media use and poor sleep quality in youth. Considering these concerns, what specific actions can adolescents and parents take to improve sleep?

A new national study, published in the Journal of Adolescent Health, offers insights into screen habits linked with better sleep.

“Ensuring adolescents get enough sleep is vital, as it supports their physical and mental growth and development,” says lead author Jason Nagata, MD, associate professor of pediatrics at the University of California, San Francisco. “Our research found that leaving notifications on, even in silent mode, leads to less sleep compared to turning the phone off completely or keeping it outside the bedroom.”

The researchers analyzed data from 9,398 preteens aged 11-12 who are part of the Adolescent Brain Cognitive Development Study, the largest long-term study of brain development and child health in the United States. Data were collected from 2018-2021.

The adolescents and their parents answered questions about their sleep habits and youth were asked about their screen and social media use at bedtime. A quarter of preteens had sleep disturbance. 16.2% reported being woken up by phone calls, text messages, or emails while sleeping at least once in the past week. Furthermore, 19.3% reported using their phone or another device if they woke up overnight.

“Adolescents can be extremely sensitive to phone notifications, often waking up instantly when they hear their phone,” said Nagata. “Even if a phone is on silent or vibrate, adolescents may still check it overnight. Once they start reading or responding to messages, they can become more alert and activated.”
