She outlines the five pillars of CBT-I, emphasizing that time-in-bed restriction and stimulus control are essential for improving sleep efficiency. The discussion covers how common habits like caffeine use and bed associations perpetuate sleep issues, and how cognitive techniques help patients manage the distress and catastrophizing that often accompany insomnia.
