Halotherapy or salt therapy is an alternative therapeutic practice that, according to some, can bring health benefits. The use of salt for therapeutic purposes is very ancient and still widespread today both in specialized centers where it is possible, for example, to perform treatments in salt caves and in the home through the use of pink salt lamps. Himalaya. Treatment involves exposure to brackish air, and although there are doubts about its effectiveness, many people claim to benefit from it. Halotherapy would be indicated, in particular, for the treatment of respiratory problems such as asthma, allergic rhinitis, chronic bronchitis, colds and nasal congestion, cough, even in smokers. Not only that: those who propose treatments with salt also claim that the negative ions released by sodium chloride into the environment are able to increase the production of serotonin in the body, making halotherapy useful in case of mood disorders, anxiety. and mild depression. Since it is believed that the salt particles are able to absorb impurities and bacteria responsible for various skin diseases, halotherapy is also used to combat skin problems, such as eczema, psoriasis and acne.

Benefits and when you need them

Salt therapy or halotherapy is recommended to combat various psycho-physical ailments. Useful benefits are attributed to this therapy in case of:

  • asthma
  • bronchitis
  • cough
  • sore throat
  • cold
  • acne
  • dermatitis
  • psoriasis
  • water retention
  • cellulite
  • muscle aches
  • anxiety
  • mild depression

Depending on the disorder to be treated, the salt is used by inhalation, taken internally or for external applications. Studies relating to halotherapy have not confirmed all the benefits attributed to salt, especially as regards its properties for skin and mood disorders. The anti-inflammatory and anti-allergic action exerted by salt on the respiratory tract have instead been partially demonstrated.

How does it work

Halotherapy treatments are generally distinguished according to the way in which the salt is administered, with or without the presence of water. The dry method involves staying in salt caves, generally artificial, without humidity and at a temperature equal to or below 20 ° C. The treatments take place in wellness centers, beauty centers and spas, usually without the presence of medical personnel. The duration can vary from thirty to sixty minutes at the most, during which air dense with particles released by the salt is breathed. In fact, inside the caves a halogenerator is placed, that is a device that chops the salt very finely, reducing it into microscopic particles that are diffused into the environment. Once inhaled, these particles would be able to absorb allergens, toxins, irritating molecules present in the respiratory tract, reducing inflammatory states, excess mucus, phlegm and bringing benefits in case of asthma, cough and allergies.

In addition to the dry method, the salt can also be used diluted in water: the saline solutions can be ingested in small quantities to assimilate the trace elements or used externally. The treatments with water and salt are used for example for gargle against cough and sore throat, mouth rinses to relieve gingivitis, stomatitis, canker sores and inflammation of the oral mucosa, nasal washes to clean the nostrils, clear the nose and fight colds, baths to relax the muscles, reduce tension, counteract swelling in the legs and feet, water retention and cellulite.


Halotherapy is believed to be a safe and risk-free treatment for most people, so much so that it is not contraindicated even for pregnant women, breastfeeding women and children. Gargles, mouth rinses, nasal washes, baths and other external applications with water and salt do not seem to cause significant side effects and, only in some cases, can cause burning or redness of the skin. As for the treatments in the cave, where brackish air is inhaled, these treatments do not seem to cause problems in healthy people who use them to combat coughs, allergic manifestations and mood disorders. People who suffer from asthma, chronic obstructive pulmonary disease (COPD) or other respiratory diseases should instead consult their doctor before undergoing this type of treatment. Like all alternative or complementary therapies, halotherapy is not intended as a substitute curative treatment for any pharmacological therapies in progress. Anyone taking medications for respiratory problems, anxiety and depression or other conditions should therefore not stop treatments without first hearing from their doctor.
