Technically known as Spelotherapy or Halotherapy this increasingly popular treatment involves inhaling a fine aerosol mist of therapeutic grade salt. It is a common natural non-invasive treatment originating in eastern and central Europe and is now being widely used all over the world. Across Eastern Europe the treatment is often recommended by doctors and is even covered by health insurance. Practiced since the 18th century the therapy is shown to have many health, healing and wellness benefits.
