Mindfulness: What It Is and How to Practice It

Halotherapy, also known as salt therapy, is a wellness practice that has been gaining attention in recent years. It leverages the therapeutic properties of salt to potentially alleviate various health conditions. This blog post provides details on halotherapy, its mechanisms, potential side effects, and therapeutic applications.
Halotherapy is a form of alternative treatment that involves exposure to sodium chloride particles. The process utilizes microclimates saturated with sodium chloride, which can be either artificial or natural, such as those found in salt caves or rock salt mines, a practice known as speleotherapy.
The roots of salt therapy can be traced back to ancient times. In ancient Greece, for example, inhalation of salt water vapors was recommended for relief from respiratory tract inflammation. In the modern age, halotherapy involves inhaling an aerosol composed of micronized sodium chloride. The patient is placed in a specially designed "salt room" that replicates the microclimate found inside a natural salt cave.
Medical devices known as salt halogenerators or micronizers are used to reduce dry pharmaceutical grade salt into micrometric-sized particles, which are then ionized. These tiny, negatively ionized salt particles create an aerosol that can travel deep into the respiratory system, reaching the lungs at the alveolar level.
The negatively charged aerosol is easily inhaled with the natural breathing rhythm, as the salt particles are very small and almost imperceptible. Once inhaled, the salt can reach the deepest level of the lungs, where it dissolves, attracting positive charges, such as small impurities, air pollutants, or allergens, which are then expelled through coughing, the bloodstream, or through other metabolic processes.
Potential benefits of aerosol therapy with hypertonic saline inhalation include:
In rare cases, temporary phenomena such as itching, skin irritation, throat, and eye irritation may occur during treatment. Halotherapy is not recommended for patients suffering from acute states of respiratory pathologies, intoxication due to alcohol or drugs, heart failure, recent bleeding or nosebleeds, hemoptysis, or severe systemic hypertension.
Halotherapy has been suggested to be beneficial for a variety of conditions, particularly those related to respiratory and skin health. Some of these include allergies, allergic rhinitis (or hay fever), colds and flu, cough, asthma, sinusitis, tonsillitis, chronic bronchitis, chronic obstructive pulmonary disease, emphysema, cystic fibrosis, and ear infections.
Moreover, relief from symptoms of various dermatological diseases, such as psoriasis, eczema, dermatitis, and other skin irritations, has also been observed. Halotherapy is believed to help normalize the skin's superficial flora.
Professionals in the field emphasize that halotherapy can induce a mucolytic, anti-inflammatory, immunomodulatory, and hyposensitizing (antiallergic) effect. However, it's crucial to understand that halotherapy should be viewed as a complementary form of natural medicine and should not replace conventional medical therapy.
