Here's a question to which I've not been able to get clear answer to date, after researching widely online, and also consulting multiple doctors and ENTs: Is it normal, when lying in a horizontal position, to always have one side of one's nose blocked off and not passing air, swapping sides on a time scale similar to the nasal cycle?

The nasal cycle is well-known but is not said to be related to lying in a horizontal position. It is said to be distinct from pathological nasal congestion and obstruction.

In summary: What proportion of people experience total one-sided nasal obstruction when lying horizontal (majority of people, or otherwise)?

  • I think the answer is it's normal for you. Everyone has unique physical quirks. But this isn't a question that can be answered with objective facts. – Carey Gregory Apr 17 '20 at 15:16
  • @CareyGregory: I'll politely disagree. "Do the majority of people experience nasal obstruction when lying horizontal?" seems very much like a factual, yes-or-no question. It's puzzling to me why it's apparently so difficult to answer. – Daniel R. Collins Apr 17 '20 at 19:00
  • Well, this site requires questions to demonstrate some degree of prior research. What has your research revealed so far? – Carey Gregory Apr 18 '20 at 0:28

    It's not a hard question, but you've added enough now to make it a reasonable question. Did you notice that the nasal cycle link you provided addresses your question? – Carey Gregory Apr 18 '20 at 15:28

    There is a similar question here which has an answer which gives a detailed answer to the nostril cycle phenomenon you mentioned at medicalsciences.stackexchange.com/a/3967/7951 However, this is mostly a copy and paste of a more detailed answer at biology.stackexchange.com/a/21219/29337 Although it doesn't mention anything about the phenomenon while laying down, I would say that it applies then too. – Chris Rogers Apr 20 '20 at 8:42
