I like this study, while i too view companies that sponsor their own research with a skeptical eye. This sounds a whole lot like a sinus flush, yes only a little spray, but a good start. The sinuses are dark and moist bug factories. There is plenty of anicdotal as well as good research that says a netti pot sinus flush with some sea salt in it will shorten the duration of a cold. Maybe sea salt has some bug squashing, or at least bug hindering properties. You keep things from being spoiled by bacteria by salting them. I like anything that has potential benifits with little or no side effects.
