I would love to sit inside a salt room. So cool that you got a chance to try it. I remember there was some controversy circulating several years ago about the safety of the 28 trace minerals in the salt and the fact that the salt has not been processed and filtered makes it unsafe. As with most folk medicine, the scientific circle does not support claims of any health benefits (there have been few studies conducted) but they also say that it's no better/worse than other salts. I always get nervous when I see claims of any kind on things that we use and end up wasting hours researching. Half the time there is no conclusive evidence either way.

For me, the fact that it works and makes me feel better and prevents me from inhaling all the junk they put in inhalers is enough evidence that it's not doing me harm.

Here are some details on one study that you might find interesting. The link to the actual study did not work but I'll dig around for it.
