NCT ID NCT07156383
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how Cognitive Behavioral Therapy for Insomnia (CBT-I) affects the body's stress system, including the hormone cortisol. Researchers will track 115 adults with chronic insomnia, measuring sleep and stress markers before, during, and after therapy. The goal is to understand why CBT-I works and whether it helps people with short sleep more than those who sleep longer.
