Sodium chloride (commonly known as salt) is widely used in the form of saline solutions to help alleviate nasal congestion associated with colds. The primary application is as a nasal irrigation or saline nasal spray, not as an oral decongestant. Saline nasal sprays or rinses work by moistening the nasal mucosa, thinning mucus, and helping to clear out allergens, irritants, and infectious agents from the nasal passages. Several clinical studies and systematic reviews support the use of isotonic or hypertonic saline solutions for symptomatic relief of nasal congestion and for improving nasal hygiene during upper respiratory tract infections, such as the common cold. However, while saline irrigation can reduce the severity and duration of some symptoms, its effects are generally mild and it does not act as a pharmacological decongestant (it does not constrict blood vessels in the nasal mucosa like medications such as pseudoephedrine). The evidence base is robust enough to recommend saline as an adjunctive, safe, and non-pharmacological therapy, especially suitable for children and those seeking to avoid medication side effects. Guidelines from organizations such as the American Academy of Otolaryngology also endorse saline irrigation for symptomatic relief. Thus, sodium chloride is scientifically validated for supporting relief of nasal congestion, but the level of effect is moderate and not curative.
