Halotherapy is a treatment based on the natural ions in the salt. An ion is a particle that has electricity. The ions are created in nature as air molecules break apart from sunlight radiation or moving through air or water.
Negative ions have a positive effect whereas positive ions have a negative effect on people. When ionization occurs calcium and sodium in the blood increases and purifies the blood which becomes more alkaline.
This is important because certain bacteria, viruses and cancers cannot live in an alkaline environment. Other potential effects of halotherapy include helping reduce inflammation and lessen mucus production, making it easier to breathe.
