At any given moment, one nostril is dominant for airflow, the other is partially congested. This prevents the nasal mucosa from drying out. A cold simply hijacks this mechanism, turning a partial, healthy congestion into a total, miserable one.

A "stuffy" nose is, in most cases, a temporary vascular erection, not a plumbing blockage. This paper argues that effective decongestion is not about removing goo, but about outsmarting the autonomic nervous system. Most people believe both nostrils work equally
