A study reports that sleeping for longer—around nine hours or more in bed—is associated with a higher risk of dying from any cause. The research compares mortality outcomes across different sleep-duration ranges and finds that the risk increases at the longer end.
The outlets describe a “sweet spot” for overall health at about seven to eight hours of sleep. By contrast, they say people who sleep less than six hours are also at risk, but the emphasis in the reporting is that the higher mortality is observed in those who spend more time sleeping. The coverage does not present details on underlying causes, study design, or whether sleep duration reflects illness rather than being the direct cause.
Overall, both sources convey the same core finding and interpret it as evidence that spending more time in bed than roughly seven to eight hours correlates with a greater likelihood of earlier death, based on the study they reference.
