Stable Sleep Pattern Before Sleep Loss

Completed · Not applicable

Conditions studied: Sleep

In brief

Sleep is now recognized as important for disease prevention. Too little or too much sleep contributes to cardiovascular disease. Leading health organizations recommend adults sleep 7-9 hours per night for optimal health. This recommendation is based on research that finds reductions in sleep duration elevate blood pressure and impair vasodilation of blood vessels. One question raised in a recent NIH Workshop report (PMID:36448463) is whether stable sleep patterns, irrespective of a person's sleep duration, could mitigate the adverse effects of insufficient sleep on vascular function. This project will address this question in midlife adults using a randomized, crossover designed study.
