How evening screen light and content affect children's sleep and mood

Experimental effects of light and content from evening screen media use on children's sleep, executive functioning, and emotion regulation

NIH-funded research Baylor College of Medicine · NIH-11184308

This project looks at whether the light and exciting content from evening screen use makes sleep, mood, and thinking worse for children ages 8 to 11.

What this research studies

If your child takes part, researchers will enroll about 200 children ages 8 to 11 and expose them to different evening screen conditions that vary in screen light and how stimulating the content is. They will measure sleep and circadian timing with objective tools and track next-day emotion regulation and executive functioning. The study uses controlled, night-by-night comparisons to separate the effects of light from the effects of arousing content. Results are intended to help parents make clearer choices about screen use before bedtime.

Who could benefit from this research

Good fit: Ideal participants are school-aged children about 8 to 11 years old who regularly use screens in the evening and can attend study visits at Baylor in Houston.

Not a fit: Infants, children under 8, older teenagers, or children who do not use screens in the evening are unlikely to be eligible or to benefit directly from this project.

Why it matters

Potential benefit: If successful, the results could give parents clear guidance on evening screen use to help children sleep better and improve mood and daytime thinking.

How similar studies have performed: Most prior work is observational and shows links between evening screen time and poor sleep, but controlled experimental studies in children are limited, so this approach is relatively new.
