What is Stellar Sleep?
Stellar Sleep is a digital platform focused on providing support for people experiencing chronic insomnia. Initially developed within the Harvard Innovation Labs, the application is based on the principles of Cognitive Behavioral Therapy for Insomnia (CBT-I). It provides a structured program intended to identify and address behavioral and psychological causes related to sleep difficulties. The service is provided via a mobile application and a national network of clinicians in the United States. The tool is designed to provide personalized tracking, allowing users to work on their sleep habits through short daily modules. The approach focuses on targeted intervention for cognitive mechanisms rather than isolated symptoms.
