Cardiovascular Risk and Circadian Misalignment in Short Sleepers - Role of Extended Eating Period
United States100 participantsStarted 2023-12-05
Plain-language 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.
