About this study

Evidence suggests that roughly 30% of the US adult population sleeps less than 7 hours per night, and those who do show 20-52% increased risk to develop cardiovascular diseases, particularly hypertension. 

The purpose of this study is to look at the cardiovascular and metabolic effects of prolonged sleep in prehypertensive and stage 1 hypertensive people who report habitual short sleep.
