If you have experienced the pleasure of visiting a beach or natural salt cave, you may appreciate the growing appeal of salt therapy or, officially, halotherapy. Spa centers and eager guests believe this approach can alleviate conditions ranging from asthma and pneumonia to acne, stress, and fatigue. Although some medical professionals bemoan a dearth of substantial scientific evidence for halotherapy, a remarkable body of research does support the mounting anecdotal claims of the treatment's benefits.
Halotherapy is a dry salt therapy that involves a special nebulizer called a halogenerator. This equipment mills pharmaceutical-grade sodium chloride into microsized particles and emits those particles into the air of a salt room (haloroom or halochamber). The Salt Therapy Association refers to this space as an active salt room. The airflow, temperature, and humidity are controlled in both active and passive salt chambers. Like their counterparts, passive salt rooms are filled with Himalayan, Mediterranean, Dead Sea, or a combination of salts, but they do not have halogenerators. Consequently, passive rooms have a lower concentration of salt than active rooms. Industry leaders maintain that true, effective halotherapy is the inhalation and absorption of microsized salt particles, and can therefore only be achieved with a halogenerator.
