An expert look at research around screen use at bedtime, which has ballooned since the emergence of smartphones in 2007, found that pre-bedtime use of the devices impairs the sleep health of children and adolescents. 

The international panel of sleep experts, led by Professor Lauren Hale of Stony Brook University in New York, were selected by the National Sleep Foundation. After assessing 574 peer-reviewed published studies on screen time and its effects on children, adolescent and adult sleep, the panel created a consensus statement about digital screen use and sleep, says a university news release. 

The consensus statement, titled “The Impact of Screen Use on Sleep Health Across the Lifespan: A National Sleep Foundation Consensus Statement,” is published in Sleep Health, the journal of the NSF. 

The release said the consensus found that "on general, screen use impairs sleep health among children and adolescents; the content of screen use before sleep impairs sleep health of children and adolescents, and behavioral strategies and interventions may attenuate the negative effects of screen use on sleep health." 

“Upon review of the current literature, our panel achieved consensus on the importance of reducing pre-bedtime digital media to improve sleep health, especially for children and adolescents,” Hale said in the release. “We also identified the gaps in the literature and the need for future research.”

The NSF offers recommendations for best practices to reduce the impact of screen use on sleep, including: 

• Near bedtime, avoid material thay is stimulating or upsetting
• Have early, regular, and relaxing bedtime routines without screens
• Set time limits on screen use, especially in evening and at night
• Talk with kids about how using tech and screens can impact sleep
• Model appropriate nighttime screen use for children
