The determining factor of recommended treatments depends on the type and severity of the condition being treated.  Those with chronic respiratory and skin conditions like asthma, bronchitis, sinusitis, allergies and psoriasis may benefit by visiting the salt cave once or twice a week over a four week period.  Many feel improvement after one or two sessions but continued sessions may be required to achieve long-term results.  Salt therapy is also used as a preventative measure to help strengthen the immune system against colds, cough, allergies and sinus issues.
