The salt is grounded into tiny micro particles by our halogenerator and then dispersed into the air. The salt widens the airways and loosens the mucus, which begins to clear quickly, and inflammation is reduced, which makes more room in the airways for you to breathe. We can seat five people at once every hour. Great for a girls' day or bridle party. It is our hope that you are so relaxed you fall asleep and do your best deep breathing, and reap the benefits of our salt rooms.
