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.

Active substance

amber-tinted glasses and smart lightbulbs

What this could lead to

If it works, this could point toward a simple, drug-free way to help young children fall asleep faster by adjusting evening light exposure.

What could go wrong

This is a very early feasibility study with only 60 children. It is not designed to prove the intervention works, only that it is practical to test. Results may not apply to all children.
