Many of us have heard of sleep apnea as it relates to snoring. Just google sleep apnea and the advertisement abound of how you can stop your snoring with appropriate CPAP ( Continuous Positive Airflow Pressure) type of devices
But what is sleep apnea? Wikipedia has this definition: ‘…a sleep disorder characterized by abnormal pauses in breathing or instances of abnormally low breathing, during sleep..”
And three main types:
• Obstructive sleep apnea: as the name implies something impedes the passage of air in the passages shown in the figure above. Probably the apnea involved with snoring
• Central sleep apnea: Rarer, involves the nervous system. Some diseases like Lupus and Multiple Sclerosis have been mention with a loose connection with such sleep apnea
• Mixed apnea and complex sleep apnea
The connection with cardiovascular issues has been studied [2,3]. Obviously , Congestive Heart Failure (CHF) and sodium do not mix well…Then sleep apnea has connections with CHF. So it is not too surprising that there would be an interaction sleep apnea and sodium!
The way  puts it , though is interesting: “…The purpose of this study was to test the hypothesis that severity of sleep apnea (SA), assessed by frequency of apneas and hypopneas per hour of sleep (apnea-hypopnea index [AHI]), is related to sodium intake in patients with heart failure (HF)…” In other words sodium would aggravates sleep apnea, at least for CHF patients.
Hmmm…Anyway there is a suspicion that sleep apnea can bring cardiovascular issues, even inflammation.
Many sites such as the Mayo Clinic have a discussion on sleep apnea symptoms
