In addition to the production of pure rock salt, established in March 2007 was the world’s biggest Speleotherapy center. It is a twenty-bed therapy center for the patients with respiratory disorders, especially the asthmatic patients.
For many years, Khewra salt mine has been a great attraction for the tourists from all over the world. Moreover, it also attracts a lot of asthma patients each year from all around the country.
Khewra’s salt therapy center is similar to the previously built salt resorts in Poland and Ukraine. The patients spend about 12 hours daily in the therapy center for a total of 10 days of therapy. The sterile environment has salt aerosols naturally dispersed in the air. These salt micro-particles have antibacterial effects, so they help to clear out air passages in the lungs of the respiratory patients, consequently causing an ease in breathing. The recovery percentage for young and old patients is about 70% and 50% respectively.
