Blue light blockers for bedtime: a new hope for tired tots?
NCT ID NCT07391852
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether reducing blue light exposure in the evening—using amber-tinted glasses or smart lightbulbs—can help children ages 5 to 6 fall asleep faster. Sixty children with sleep difficulties will be randomly assigned to one of three light-reducing strategies for two weeks. The main goal is to see if these approaches are practical and acceptable for families, not yet to prove they improve sleep.
