Summary

The objective of this study is to elucidate the potential mechanisms responsible for the increased risk of cardiovascular disease among patients with hypertension and comorbid insomnia.

Description

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.
