Halotherapy means 'salt therapy' and has been used extensively in Europe for health and wellness. While it may seem strange that salt can effectively treat everything from asthma to eczema, there is an easy explanation. But first, a little halotherapy history:
The first known use of halotherapy was by the ancient Greeks and Ayervedic culture in India. Hundreds of years ago, European monks observed that patients treated in salt caves recovered rapidly from illness. In the 1800's, the Polish government documented that salt miners were not only more healthy than coal or metal miners, but even healthier than the general population. During WWII, salt mines were used in Germany as bomb shelters, where asthmatics noticed their breathing improved. By the 1950's halotherapy was being scientifically studied in Russia. Soon after, halotherapy 'salt rooms' or 'salt chambers' were being constructed above-ground to recreate a salt cave or salt mine environment. A study recently presented at a Vienna medical conference found that a tabletop salt generator helped prevent colds.
