We talk a lot about how much sleep we get.
But what about when we sleep?
A prospective cohort study looked at sleep regularity in more than 60,000 adults and found that, compared with the least regular sleepers, people with more consistent sleep-wake patterns had lower risks of all-cause, cancer-related, and cardiometabolic mortality.
Most interestingly, sleep regularity was a stronger predictor of all-cause mortality than sleep duration in the researchers’ models.
That doesn’t prove that going to bed at the same time will make you live longer.
But it does suggest that good sleep may be about more than just total hours.
Rhythm matters.
This week, try picking a realistic bedtime and wake time and keep them reasonably consistent—even on the weekend.
You don’t need perfection.
Give your body a rhythm it can rely on.
