Sleep matters: Duration, timing, quality and more may affect cardiovascular disease risk

Healthy sleep includes multiple components, such as number of hours of sleep per night, how long it takes to fall asleep, daytime functioning and self-reported sleep satisfaction.

Addressing these different dimensions of sleep may help to reduce cardiometabolic health and related risk factors.

Sleep duration, continuity, timing, satisfaction, regularity and daytime functioning.

Day-to- day variability in sleep timing has been associated with a higher risk of cardiovascular disease.

Excessive daytime sleepiness is associated with cardiovascular disease, coronary heart disease, stroke and death.

Black adults have the worst sleep health among all people, with Black adults having the worst.

More research needed to optimize sleep health.

There is a need for evidence from clinical trials confirming that improving sleep health leads to better cardiometabolic health .

This data could be useful in developing effective interventions to help people improve various components of their sleep.

Research studies on multidimensional sleep health would ideally include collaborative efforts across medical specialties.
