Recent studies have shown that snoring is not only bad for the person snoring, but can also cause sleep deprivation in the person who shares a bed with the snorer. That’s my interpretation of the following summary of the study:
“We have previously identified heavy snoring as an independent risk factor for carotid atherosclerosis. In order to explore the hypothesis that snoring-associated vibration of the carotid artery induces endothelial dysfunction (an established atherogenic precursor), we utilized an animal model to examine direct effects of peri-carotid tissue vibration on carotid artery endothelial function and structure.
What? Basically, the researchers took rabbits, let them fall asleep and then used snoring sounds to let the napstealing begin. Other rabbits, who weren’t exposed to snoring sounds were said to have slept better. Really? You think? And then, another brilliant statement to summarize the hypothesis of the study is:
“Features of OSA such as hypoxemia, large intra-pleural swings and blood pressure volatility were prevented. Carotid endothelial function was then examined: (1) biochemically by measurement of tissue cyclic guanosine monophosphate (cGMP) to acetylcholine (ACh) and sodium nitroprusside (SNP); and (2) functionally by monitoring vessel relaxation with acetylcholine in a myobath.
It’s a good thing you have me to explain the nefarious napstealing going on in this study, because otherwise, you would be stuck reading things like this:
“Vessel cGMP after stimulation with ACh was reduced in vibrated RCA compared with unvibrated (control) arteries in a vibration energy dose-dependent manner. Vibrated RCA also showed decreased vasorelaxation to ACh compared with control arteries. Notably, after addition of SNP (nitric oxide donor), cGMP levels did not differ between vibrated and control arteries, thereby isolating vibration-induced dysfunction to the endothelium alone. This dysfunction occurred in the presence of a morphologically intact endothelium without increased apoptosis.
So, to sum up, if you don’t want to develop carotid atherosclerosis… (sounds bad, doesn’t it) …you need to stop sleeping with someone whos snores or fix their snoring problem. The genius behind this whole study is that you really needed a government-funded study to tell you that sleeping with someone who snores is a nefarious napstealer that can adversely affect the quality of your sleep, right? Or they could have just asked my wife.
