The Claim

A U-shaped relationship exists between self-reported total sleep time and predicted 10-year cardiovascular risk, with the lowest risk observed at 6–9 hours of sleep in a Hispanic/Latino clinical cohort.

In plain English

People who sleep between 6 and 9 hours a night seem to have the lowest risk of heart problems in the next 10 years — those who sleep less or more than that have higher risk, at least in Hispanic/Latino adults.

What the research says

1 study

  1. Study: The U-Shaped Association between Sleep Duration, All-Cause Mortality and Cardiovascular Risk in a Hispanic/Latino Clinically Based Cohort

    This study found that people who sleep too little (under 6 hours) or too much (9+ hours) have a higher risk of heart problems in 10 years, while those who sleep 6 to 9 hours have the lowest risk — just like the claim says.
