Cardiovascular Risk and Circadian Misalignment in Short Sleepers - Role of Extended Eating Period
Pennington Biomedical Research Center
Summary
Short sleep duration confers high cardiovascular and metabolic risk, but lifestyle factors and molecular mechanisms that contribute to increased blood pressure and poor glucose control during short sleep are not completely understood. Habitual short sleepers are constantly eating, the proposed studies will evaluate if this behavior contributes to heightened cardiovascular and metabolic risk. The study will evaluate if restricted eating duration (8 hours/day) could improve cardiovascular and metabolic health in habitual short sleepers.
Description
Short sleep duration is associated with increased cardiovascular and metabolic risk with consequent increased cardiovascular mortality. Increasing sleep duration mitigates the metabolic impairment, but alternate strategies to reduce cardiometabolic risk in habitual short sleepers are lacking. This is especially important when increasing sleep duration is unsuccessful. Unfortunately, the underlying mechanisms through which shortened sleep contributes to metabolic detriments are not completely understood. This hinders the development of alternate strategies for cardiovascular prevention in short…
