For many years we have known that heavy snoring causes major increase in risk of carotid Atherosclerosis and stroke. This has been widely established through published research.

One such research published in “Sleep” the journal of sleep disorders shows that this risk in independent of the risk for sleep apnea and nocturnal hypoxia. Carotid Atherosclerosis (hardening or clogging)  is a major cause of storkes.

In a recent published study in Sleep, it was shown that heavy snoring in absence of sleep apnea also seriously added to the risk for carotid Atherosclerosis and stroke. In this study a group of 110 volunteers were broken down into three groups based on the severity of their snoring. Mild snorers , snored less than 25% of the time, moderates snorers, snored 25-50% of the time and severe snorers snored more than 50% of the time.

The prevalence of carotid artery hardening increased along with the severity of the snoring. Non of the volunteers showed oxygen desaturation.
