– When laying on one side, why does the opposite nostril clear and seem to shift the “stuffiness” to the side you’re laying on?

Question

I’ve always wondered this. Seems like you can constantly shift it from side to side without ever clearing both!

It is a nasal cycle, one of the ultradian rhythms.

With or without stuffed nose, this happens naturally. Even applying pressure under the armpits changes the dominant nostril.
