Pharmaceutical grade salt is added to a medical device called a Halogenerator. The halogenerator grinds the salt into very microscopic particles and then disperses them into the salt room at the pre-set concentration level based on the clients needs. The relative humidity and temperature is also very closely monitored and controlled in the salt room to replicate the naturally occurring micro-climate in a salt cave or salt mine. 

While relaxing in our of our salt cabin, clients inhale the dry, salt-enriched air deep into their lungs, bronchi, bronchioles and alveoli. 

The inhaled salt has bactericide, mucokinetic, hydrophilic and anti-inflammatory properties which results in reducing inflammation on the entire respiratory tract, loosening and accelerating transport of mucous, widening of the airway passages, elimination of tar and foreign allergens and an improved immune function. Symptoms of a number of common respiratory and skin conditions subside, bringing relief to clients. Dry salt is super absorbent and acts like a sponge, picking up foreign substances along its path through the respiratory tract. Acting like a toothbrush, it helps cleanse the respiratory system removing ‘build-up’ of foreign elements that cause various respiratory ailments and conditions.

Dry and kinetically activated salt is helpful in reducing inflammation as well as breaking down mucous and moving it out of the lungs. Low concentration and gradual administration of dry salt and consistency of sessions is most effective for respiratory conditions whereas high concentration and aggressive administration with consistency of sessions is best for skin treatments. 

Skin conditions respond well to salt therapy because the salt kills bacteria and is helpful in reducing inflammation and stimulating the skins micro-circulation. This increases activity of skin cells, the ion channels and activates electrophysiological activity that determines the skin’s protective properties. The salt provides PH normalization and induces reparative and regenerative processes in derma, increasing skin rigidity, stimulating growth and hair health.

In clinical trials Dry Salt Therapy (a.k.a. “halotherapy) has proven to be effective in relieving symptoms of a variety of respiratory and skin ailments. During one of the clinical trials, Salt Therapy resulted in improvement of the clinical state in:
 

• 85% of mild and moderate asthma cases
• 75% of severe asthma cases
• 97% of chronic bronchitis,  bronchiectasis and cystic fibrosis cases

(“journal of Aerosol Medicine, A.V. Chervinskaya, Volume 8. Number 3, 1995”)

The comprehensive list in chronological order:

In addition, halotherapy contributes to an earlier restoration of the functional state of the nasal cavity.”
• Halotherapy for Chronic Respiratory Disorders: From the Cave to the Clinical (2020)
  “HT has been found to have a positive effect on patients suffering from chronic respiratory diseases, improving mucociliary elimination and lung function in common chronic respiratory diseases and also HRQoL. Currently, no official guidelines exist on the use of HT in the form of salt rooms (halo chambers) or dry powder inhalers, but evidence exists for its use as a possible adjuvant therapy. More structured research in the form of randomized clinical trials is required.”
• Optimization of pathogenetic therapy in patients with chronic obstructive lung disease (2020)
  “The proposed complex therapy of COPD patients with the inclusion of the combined drug ambroxol and acetylcysteine and halotherapy sessions contributes to the improvement of the quality of life of patients.”
• Halotherapy – benefits and risks (2018)
  “The mechanisms of action of halotherapy are manifold: mucolytic, antibacterial, anti-inflammatory, immunomodulating, hyposensitizing.
  Halotherapy is a natural and safe treatment without serious side effects. This method is very beneficial for the overall wellness of a person by improving function and removing toxic substances from respiratory system, improving the function and appearance of the skin, boosting the immune system and reducing stress.The positive results from the therapy last for more than a year. The possibility to combine it with other physical therapy methods, as well as with pharmacological therapy, makes halotherapy a treatment of choice in mild and moderate forms of bronchial asthma, chronic obstructive bronchitis, post-pneumonia states and various other respiratory and skin diseases.”
• Comparative analysis of airborne bacteria and fungi in two salt mines in Poland (2017)

• Halotherapy in Patients with Cystic Fibrosis: A Pilot Study (2015)
  “HT is associated with improvement in symptoms of sinus disease in CF, and should be explored as an adjunct treatment for CF patients”
• Theoretical basis and clinical benefits of dry salt inhalation therapy (2015)
  “Due to the greater osmotic pressure the inhaled salt diminishes the oedema of the bronchial mucosa, decreases its inflammation, dissolves the mucus, and makes expectoration easier and faster (expectoration of air pollution and allergens will be faster, too). It inhibits the growth of bacteria and, in some case, kills them. Phagocyte activity is also increased. It has beneficial effect on the well being of the patients, and a relaxation effect on the central nervous system. It can prevent, or at least decrease the frequency of the respiratory tract inflammations. It produces better lung function parameters, diminishes bronchial hyperreactivity, which is the sign of decreasing inflammation. Its beneficial effect is true not only in inflammation of the lower respiratory tract, but also in acute or chronic upper airways inflammations. According to the international literature it has beneficial effect for some chronic dermatological disease, too, such as psoriasis, pyoderma and atopic dermatitis.”

• Impact Assessment of Saline Aerosols on Exercise Capacity of Athletes (2012)
  “After the halotherapy treatment, there was an increase in the respiratory volumes (VC, MEVS, V max., PEF) for all subjects investigated. There was also an increase in the percentage of subjects with excellent respiratory index. As concerns the breathing system, there was an improvement in the breathing mechanics, as well as an increase in the oxygen saturation of arterial blood and in the resistance to apnea and hypoxia. Due to the recovery, which took place in mediums with saline aerosols, the breathing was more effective, both regarding he gaseous exchanges, and using tissue-level oxygen. The assessment of standard cardiovascular system during effort, the Martinet test, indicated better values during the final tests, and the cardiovascular assessment tests are indicators of body adaptation to effort and only indirectly of the effort capacity, allowing to assess the effectiveness of training methods used for a certain amount of time. We have also noticed a decrease in the heart rate and breathing rate during the training session effort, which was possible due to the cardiovascular adaptation and regulation of athlete’s organism.”
