When it comes to a good night’s sleep, the quality of your sleep may be more important than the number of hours you get. A new study published in the journal sleep suggests that the regularity of your sleep schedule is a strong predictor of your overall risk of death. In fact, research shows that even those who consistently get 7-8 hours of sleep but have irregular sleep schedules are at a higher risk of stroke, heart attacks, and even cancer compared to those with a consistent sleep-wake routine.
Individuals with the most consistent sleep-wake times have been found to have up to a 48% lower risk of all-cause death compared to those with inconsistent routines. However, maintaining a consistent sleep schedule doesn’t mean you can skimp on sleep. Those who slept less than six hours or more than nine hours each night were also at a higher risk of death. Overall, the link between mortality and consistent sleep patterns was found to be stronger than the link between mortality and sleep duration.
Researchers analyzed sleep data from nearly 61,000 people in the UK biobank, totaling over 10 million hours of recorded sleep. Using advanced algorithms, they tracked mortality rates over an average of 6.3 years to identify factors associated with early death. The hope is that these findings will inform updated public health guidelines and sleep recommendations, emphasizing the importance of not only getting enough sleep but also maintaining a consistent sleep schedule for improved overall health.
Further research is needed to determine if these findings apply to populations outside the UK and to a more diverse range of individuals.
