The Claim
Saline nasal irrigation reduces the duration of the common cold by approximately two days, decreases medication use by 36%, and lowers household transmission risk by 35%.
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 can help you get over a cold faster, cut down on how much medicine you need, and make it less likely to spread the cold to others in your home.
