If you don’t get this amount of sleep, you’re four times more likely to suffer from a stroke

In December of last year, I reported on a study that found those who didn't sleep for long enough were 15% more likely to suffer from a stroke within 7-25 years.

Now a new study has reached a similar (if not even more concerning) conclusion.

According to sleep researchers at the University of Alabama at Birmingham, the risk of stroke for those who sleep only six hours each night is FOUR TIMES higher than in those who get seven to eight hours of sleep.

What makes this study even more alarming is the fact that researchers excluded those who were overweight and the study only included participants who were at a low risk for obstructive sleep apnea - two risk factors for stroke.

It would therefore appear that there is a direct link between sleep deprivation and stroke risk.

Yet another reason why sleep health needs to be taken far more seriously.

    Hmmmm – still a little suspect at the “science” behind this one, although I do agree that “something” is there – a 4x difference is hard to explain by bad study design:

    “Ruiter notes that sleep duration was self-reported by participants, making it a limitation of the study, as recall accuracy can vary.

    “We need to see if sleep duration is related to actual stroke events. It would be great to learn more about what it is about sleep duration. Is it actually sleep fragmentation, or perhaps the perception of your sleep and the factors that contribute to its quality rather than sleep duration itself? These are all really important factors that are modifiable through behavioral treatment,” says Ruiter.”
