Sleep ranks second to smoking in predicting life expectancy

Insufficient sleep is one of the strongest predictors of shorter life expectancy in the U.S., surpassed only by smoking.That’s according to a new nationwide analysis published in the journal SLEEP Advances, led by senior author Andrew McHill, Ph.D., associate professor with Oregon Health & Science University (OHSU).To explore how sleep habits relate to lifespan, the researchers examined data from surveys conducted by the CDC between 2019 and 2025 across more than 3,000 U.S. counties, according to a press release.COMMON SLEEP PROBLEM TIED TO SERIOUS NEUROLOGICAL DISORDER IN MAJOR NEW STUDYSufficient sleep was defined as at least seven hours per night, consistent with guidelines from the American Academy of Sleep Medicine and the Sleep Research Society.The researchers compared average life expectancy in each county with the proportion of residents reporting sufficient sleep, controlling for traditional predictors of mortality such as smoking, diet, physical inactivity and loneliness. The researchers compared average life expectancy in each county with the proportion of residents reporting sufficient sleep.

This pattern held across most states and years studied, even when accounting for other lifestyle factors.”I didn’t expect it to be so strongly correlated to life expectancy,” McHill said in the press release, noting that although sleep’s importance to health is well-established, its association with lifespan exceeded expectations.CLICK HERE TO DOWNLOAD THE FOX NEWS APP”We’ve always thought sleep is important, but this research really drives that point home: People really should strive to get seven to nine hours of sleep if at all possible.”The research builds on a broad body of evidence linking sleep duration to health outcomes, including mortality risk, heart health, immune strength and brain function.

It also cannot establish causation and does not explain the biological factors behind the results, the researchers noted.Although the statistical models controlled for several lifestyle factors, other unmeasured variables could influence both sleep patterns and life expectancy.
