@jammer Hi there. Interesting that you bring up 'salt rooms'. It seems all the rage right now. One opened up recently in my home town as well. They offer 'reiki' as well as other meta-physical treatments along with sitting in the salt room. I don't know if you have seen our past posts about inhaled sodium chloride (salt/saline) that many of us do; but it is akin to the salt rooms. I believe that getting a prescription for the sodium chloride is probably more beneficial than trying to get enough of it from ambient exposure from a wall. You can always try it. Here, it costs $40.00 a pop. Personally, I'd do the saline in our own nebulizer at home. What are your thoughts?
