Does providing feedback and guidance on sleep perceptions using sleep wearables improves insomnia? Findings from Novel Insomnia Treatment Experiment ("NITE"), a randomised controlled trial.

Providing feedback and guidance about sensor-based sleep parameters reduced insomnia severity and sleep disturbance but did not alter sleep-wake state discrepancy in individuals with insomnia more than sleep hygiene and education. The role of sleep wearable devices among individuals with insomnia require further research.
