Sleeping too long or too short does not encourage hypertension, but having your sleep interrupted does.
That in a nutshell is what this free research paper uncovers, which was published in 2016. This is a very important distinction to make as earlier research findings vaguely described sleep problems as causing hypertension without being more careful as to the exact nature of the sleep problem.
So comparing an older research paper to this one we find that the conversation about circadian rhythm and hypertension has moved from circadian clock genes to actual observable human behavior. But, I suspect that the conversation will return back to clock genes again to explain whether interrupted sleep affects a clock gene that affects blood pressure. This new knowledge might open more doors to treatment.
Much of the text contained within this research paper is concerning methodology, a boring topic to most readers, but a necessity for the publishing researcher who does not want their findings to be criticized later by other researchers, for such discriminating peer reviews routinely, naturally and fairly occur within the realm of science.
It was my hope when I searched for hypertension and circadian rhythm research papers, that I would eventually find a research paper entitled WEARING ORANGE CLASSES AT NIGHT REDUCES HYPERTENSION: USING THE LIGHT HYGIENE APPROACH.
But alas no such paper exists.
But neither have I found the paper entitled: WEARING ORANGE GLASSES AT NIGHT HAS NO EFFECT ON HYPERTENSION: DITCH THE GLASSES AND KEEP YOUR MEDS.
The side effects of proper light hygiene may include reduced late evening productivity with increased early morning productivity.
I will be periodically revisiting this topic of hypertension and circadian rhythm to report on any new information I find.
