Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators propose to utilize a behavioral intervention to manipulate sleep quality in 150 adults with hypertension and comorbid insomnia, who will receive a 6-week Cognitive Behavioral therapy for Insomnia (CBT-I) intervention, which has been shown to markedly improve sleep quality and promote consolidated sleep in approximately 60% of those treated. A lowering of nighttime blood pressure is one of several proposed mechanisms to be examined.
