Screen time before bed: does it really ruin Kids' sleep?
NCT ID NCT06192745
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to understand how the light from tablet screens and the type of content children watch before bed affect their sleep, thinking skills, and emotions. Researchers will have 220 children aged 8 to 11 spend one hour before bed either using a bright tablet, a dim tablet, or doing non-screen quiet activities. They will measure sleep duration, quality, and changes in the body's internal clock to see which conditions are most disruptive.
