Sleep, Blood Pressure and Vascular Health

The investigators hypothesize that chronic insufficient sleep is associated with diminished endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Furthermore, the investigators hypothesize that the postulated diminishment in endothelial vasodilator and fibrinolytic function with insufficient sleep will be due, at least in part, to increased oxidative stress. Furthermore, increasing sleep duration and improving sleep quality will increase both endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Increases in endothelial vasodilator and fibrinolytic function will be due, at least in part, to reduced oxidative stress.
