The Claim
Hypertonic saline nasal irrigation and gargling reduces the duration of upper respiratory tract infections by approximately 1.9 days in otherwise healthy adults when initiated within 48 hours of symptom onset.
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 you get over a cold faster by about 2 days if you start doing it right when symptoms begin.
See the scientific wording
Hypertonic saline nasal irrigation and gargling (HSNIG) likely reduces the duration of upper respiratory tract infections by approximately 1.9 days in otherwise healthy adults when initiated within 48 hours of symptom onset, based on a pilot randomized controlled trial with 61 participants. This suggests a potential non-pharmacological approach to managing common cold symptoms, though larger confirmatory studies are needed.
What the research says
1 studyThe study tested saltwater rinses for colds and found they shortened sickness by about 2 days, just like the claim said, but it was a small test so bigger studies are still needed.
