Associations of Accelerometer-measured Sleep Duration with Incident Cardiovascular Disease and Cardiovascular Mortality.

Cohort Study

Human

2024 Nov 8

This study used wristbands to track how long people slept and found that those who slept 7 to 9 hours had the lowest risk of heart problems — sleeping less increased risk, but sleeping more didn’t. This matches the claim perfectly.

Similar Assertions

People who sleep more than 9 hours a night don’t seem to have a higher chance of heart problems or dying from heart issues than those who sleep 7 to 9 hours, at least based on how their sleep was tracked with a wrist device.
