Quality of sleep is often judged by the number of hours we sleep, but recent research suggests that the timing of sleep may be more crucial than the duration.
A study published in the journal Sleep indicates that the consistency of your sleep schedule, rather than just the number of hours slept, is a strong predictor of your risk of mortality. Even individuals who consistently get 7-8 hours of sleep but have irregular sleep patterns were found to be at a higher risk of stroke, heart attacks, and cancer. On the other hand, those with a consistent sleep routine had up to a 48% lower risk of death from all causes.
It’s important to note that simply sticking to an erratic sleep pattern with minimal hours of sleep is not advised. The study found that individuals who slept less than six hours or more than nine hours per night had a higher risk of mortality. While sleep duration is significant, the link between mortality and consistent sleep patterns was stronger.
Researchers analyzed data from nearly 61,000 individuals in the UK Biobank, totaling over 10 million recorded sleep hours. By studying sleep patterns and mortality rates, they identified the factors associated with an increased risk of early death.
These findings may lead to updated public health guidelines on sleep recommendations, emphasizing the importance of not only getting sufficient sleep but also maintaining a consistent sleep schedule for overall health improvement.
Further research is needed to determine if these findings are applicable to a broader population beyond the UK.
