OMG! This actually works. It made my lungs feel brand new. But first let me tell you about my experience. I arrive 10 minutes early for my Groupon appointment which was a salt room experience for an hour. The man at the counter was extremely excited to see me and full of information about how the salt room helps with sinus, anxiety, depression, lung issues and so much more. He showed me the room first and asked if I had any more questions before the session. I took my shoes off and stepped into the room full of salt bricks and salt sand on the floor. I walked over to a zero gravity lounge chair and started my relaxing experience. The air is pumped with salt and it is a different experience. It doesn't make your eyes hurt or anything it just feels like your at the ocean smelling the salty sea water times 1000. Very relaxing music plays while you relax in the lounge chairs. Once the session was over they crack the door so you know it's over but to my surprise he asked if I wanted additional time in the room. I obliged and had about 15 extra minutes in the room. Extremely good service. I was thanked and asked to come back at the end of the session. Afterwards I felt relaxed like I had napped. My lungs feel so clear, I'm not coughing or clearing my throat as I usually do. I really feel like this helped. I will be back and urge.you to check it out. It's worth a try.
