Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured, evidence-based treatment that helps people with chronic sleep problems by reshaping the thoughts, behaviors, and habits that interfere with restful sleep. Recommended as a first-line therapy for insomnia, CBT-I typically includes techniques like stimulus control, sleep restriction, relaxation training, and cognitive restructuring to address the root causes of poor sleep rather than just the symptoms.

If you're struggling with sleep or other unexplained issues, understanding what's driving them is the first step toward relief. A free, instant, online symptom check can help you identify possible causes, clarify your next steps, and decide whether CBT-I or another treatment path may be right for you—no appointment or cost required.
