There are a few studies. Some are inconclusive, some say it helps shorten infection and prevent hospitalization, some say it doesn't do anything. It doesn't hurt so why not. I have bad allergies already. The virus is doing all its replication in the nose so if you can reduce particles there, it might be beneficial. I think some of the studies are using a little iodine so maybe that's needed instead of just salt.
