The Claim
Hypertonic saline nasal irrigation and gargling is associated with a reduction in illness duration by approximately 2.6 days in adults with common coronavirus upper respiratory tract infections (HCoV-229E, NL63, HKU1, OC43), based on a post-hoc subgroup analysis of 15 participants from a pilot randomized controlled trial.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Using saltwater nose rinses and gargling might help adults with common colds caused by certain coronaviruses feel better about 2.6 days faster, according to a small study.
