Halotherapy

the therapeutic use of salt usually by inhalation of an aerosol composed chiefly of fine salt particles and circulated in an enclosed area

Halotherapy—from the Greek "halos," which means "salt"—uses dry aerosol micro-particles of salt or minerals inside of a large, arid space to simulate the microclimate of salt mines, says Dr. Niket Sonpal, assistant professor at Touro College of Medicine. Salt exposure as a therapeutic treatment developed after 1843, when Polish physician Feliks Boczowski noticed that his patients, who worked in salt mines, had no respiratory or lung problems compared to other miners.
