Can a smartphone app cure insomnia in teens? new trial aims to find out
NCT ID NCT07405775
First seen Jun 26, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This pilot study tests whether a smartphone app called SleepFix, combined with support from a psychologist, can help young people aged 16-24 with insomnia. The app uses sleep restriction therapy to reset sleep patterns. The trial will check if the approach is practical and acceptable, and measure changes in sleep quality, fatigue, and mood. Results will guide a larger study.

- What this could lead to
- If successful, this could provide an accessible, app-based treatment option for young people with insomnia, reducing symptoms and improving sleep quality.
