Active

Active dry salt therapy is simple to understand. There are three primary characteristics of pure sodium chloride, NaCl, known as salt:

1. Salt is super absorbent (especially when it is completely dry)
2. Salt is anti-bacterial
3. Salt is anti-inflammatory

This type of dry salt is placed into a halogenerator that then precisely grinds the salt into specific micro-sized particles and then disperses the salt aerosol into the air in a closed environment such as a room or chamber.

As the salt travels in the salt room, these salt particles of dry sodium chloride are inhaled into the respiratory system. The dry salt naturally starts absorbing allergens, toxins and foreign substances into your lungs and throughout your respiratory tract. Dry salt may help to reduce inflammation and open airway passages. The micro-sized crystal structure of pure NaCl particles breaks loose and clears out all of the ‘bad stuff’. This is the basis for how dry salt therapy can impact people suffering from respiratory conditions like allergies, asthma, bronchitis, cystic fibrosis, COPD and others.

The properties of dry salt also absorb impurities and provide anti-bacterial properties that benefit the skin such as acne, psoriasis and eczema as well as regulates the skin’s micro-circulation. The smaller particles can reach beneath the skin’s surface and absorb moisture towards the skin. The larger salt particles land on the skin and absorb any bacterial and foreign substances. The dry salt accelerates cell rejuvenation and improves skin rigidity.

The climate conditions in a dry salt room therefore must maintain certain temperature and humidity levels and proper ventilation to ensure the efficacy of the salt therapy and provide a ‘clean-air’ environment for the consumer.

Passive

Passive salt rooms were created to mimic the natural salt caves found in Europe. These salt rooms may have large volumes of various types of salt décor inside a climate-controlled room. There may be Dead Sea, Himalayan, Rock or other salts lining the walls, ceilings and floors in these types of rooms. While today’s modern passive salt rooms often look like a natural salt cave environment, they do not provide the same salt air particles provided in natural salt caves since there are no direct actions like the mining activities (crushing, grinding, chiseling, etc.) to produce salt particles in the air.

There are some known properties of having large amounts of salt in this type of confined space that provides a clean-air environment and alters the energy frequencies in the room. Some salt dust may occur from the disturbance of the salt by people walking through the salt on the floor or by some other means. There are claims that heating Himalayan salt, similar to bulb heated salt lamps, generates negative ions which eliminate the positive ions that stem from electromagnetic waves from the various technologies and pollution that we are constantly exposed to. There is some salt erosion that when the salt evaporates, some salt particles are released in the air, but all of the modern research is based on precise sized particles of pure sodium chloride being consistently dispersed into the room at certain concentration levels over a period of time, which passive dry salt rooms do not provide.
