How it works

Cognitive Behavioral Therapy for Insomnia (CBT-I) combines sleep restriction (limiting time in bed to build sleep drive), stimulus control (associating the bed only with sleep), sleep hygiene education, cognitive restructuring (challenging unhelpful beliefs about sleep), and relaxation techniques. It targets the behavioral and cognitive patterns that maintain insomnia, rather than using medication.

Oxybutynin blocks acetylcholine receptors in the central nervous system, which may reduce sweating and hot flashes by acting on temperature regulation pathways.
