The American Heart Association's 2026 Heart Disease and Stroke Statistics Update places sleep among the daily behaviors most tightly tied to heart health.
Nearly one in two US adults now lives with some form of cardiovascular disease.
Among adults aged 35 to 64, county-level hypertension-related cardiovascular death rates rose from a median of 23.2 per 100,000 in 2000 to 43.4 per 100,000 in 2019.
That near doubling is one of the report's central alarms.

Sleep patterns
The update describes sleep debt and irregular sleep patterns as increasingly common in US adults.
Nearly one in three logs at least one hour of sleep debt.
Large population studies now link poor sleep to higher risks of hypertension, diabetes, obesity, and physical inactivity.
Those are the same conditions driving current heart disease trends.

There is a hopeful side. People who improved their sleep over time showed significantly lower cardiovascular disease risk, according to the update.
That is why the AHA now treats sleep as a core pillar of prevention.
Life's essential 8
Poor sleep raises blood pressure, disrupts glucose control, and shifts appetite hormones.
Over years, that pushes blood pressure, blood sugar, and waist size in the wrong direction.

The AHA added sleep to its Life's Essential 8 heart-health checklist, recommending 7 to 9 hours per night for adults.
Adults who score in the ideal range across all eight metrics have roughly a 74 percent lower risk of cardiovascular events than those with poor scores.
What it means for your night
The AHA estimates that up to 80 percent of heart disease and stroke is preventable through modifiable behaviors and risk-factor control.
Sleep sits alongside diet, activity, tobacco avoidance, cholesterol, blood pressure, blood sugar, and weight on that list.

For most adults, that means anchoring a consistent bedtime and protecting a 7 to 9 hour window.
Recurring problems like loud snoring, gasping, or heavy daytime sleepiness are worth taking to a clinician who can screen for sleep apnea.
Catching up on lost sleep on weekends may soften some damage from short weeknights, but it does not replace steady sleep.
Nearly 916,000 Americans died from cardiovascular disease in 2023, roughly one death every 34 seconds.
