A couple of days ago I played down the health consequences of short sleep durations.
Now a study has found that there's no link between sleep deprivation and hypertension.
It's often thought that insomnia and high blood pressure are linked.
This latest study may have debunked that theory.
The Canadian cross-sectional study looked at the sleep histories of over 12,000 individuals and found no significant association between insomnia symptoms and high blood pressure (hypertension).
This held true even after looking at different degrees of insomnia severity and frequency.
Although those with higher insomnia symptom frequency were more likely to be diagnosed with hypertension or to be taking hypertension medication, after controlling for covariates, this link was not significant.
Perhaps it's time we focus more on sleep quality rather than sleep quantity.
