Most of us have heard the advice to get eight hours of sleep a night. But is that really what we should be aiming for? According to a new study, it might be time to reconsider that age-old advice.
The study, which was conducted by researchers at the University of California, San Francisco, found that people who slept for less than six hours a night or more than eight hours a night were more likely to die than those who slept for seven hours a night.
So, what does this mean for the eight-hour sleepers out there? Should we all be aiming for seven hours of sleep a night?
Not necessarily. The study only found an association between sleep duration and mortality, which means that it’s possible that there are other factors at play. It’s also worth noting that the study only looked at a small group of people, so it’s possible that the results are not generalizable to the population as a whole.
That said, the findings do suggest that there may be something to the idea that eight hours of sleep is not always the best option. If you’re struggling to get eight hours of sleep a night, it might be worth trying to aim for seven instead.
