The Claim

In a clinically based Hispanic/Latino adult cohort, self-reported sleep duration of 9 hours or more per night is associated with a 3.97-fold higher risk of all-cause mortality compared to 6–9 hours of sleep, independent of cardiovascular risk factors and obstructive sleep apnea severity.

In plain English

People in this group who say they sleep 9 hours or more each night are nearly four times more likely to die from any cause than those who sleep 6 to 9 hours, even when you account for heart problems and sleep apnea.
