Details and patient eligibility

About

The study aims to validate the effect of sleep restriction and stimulus control on improving chronic insomnia patients' sleep habits and maladaptive sleep behaviors.

Full description

The purpose of sleep restriction is to reduce the patient's time in bed, bringing it closer to their actual sleep time, thereby improving sleep efficiency and quality. Stimulus control, on the other hand, aims to associate the bed with a rapid sense of falling asleep, reducing the negative association between the bed and insomnia.
