In medieval Europe, salt industry workers found that salt mine workers rarely suffered from rhinitis, asthma, pneumonia and other respiratory diseases. In 1843, Polish scholars confirmed that in the special structure of the cave, the unique microcirculation climate combined with saturated salt dust is the main factor in curing respiratory diseases, and named this therapy "cave salt therapy". In 1858, the city of Wieliczka, Poland established the first recuperation center with professional breathing conditions, using the abundant ultrafine dispersed dry salt aerosol in the cave microenvironment for rehabilitation treatment. After that, Poland, Germany, Austria, Switzerland, Hungary, Romania...many western countries have developed natural salt caves to treat and improve the respiratory and immune systems. At the same time, in order to meet the needs of more patients, authoritative European medical institutions have developed a dry salt particle generator, which successfully simulates the particle size and concentration of salt in natural salt caves in artificial salt chambers. At present, "Cave Salt Therapy" has been recognized as an efficient non-drug treatment method by European and American countries. More than 5,000 artificial salt rooms provide continuous and effective services for people with different health needs in enterprises, schools, communities, nursing homes, and health centers. .

Dry salt aerosol salt mist therapy is a natural and healthy non-drug therapy natural therapy: cave salt therapy dry salt aerosol technology (DSA) referred to as "salt therapy", refers to the micro-climate environment similar to the creation of salt mine caves, Methods of administering non-pharmacological treatments to patients. Main principle: Salt is a natural fungicide, safe and reliable. Dry salt particles can dehydrate the bacterial protein structure, have the functions of sterilizing and anti-inflammation, dissolving sputum, and improving tracheal ventilation. Since 2006, many European health resorts, spas and fitness centers offer effective salt therapy that helps improve the respiratory system and psycho-emotional state. If you have neither the time to visit natural salt caves on a regular basis nor travel to the seaside, you can go to professional venues or help you create your own professional salt room. It perfectly imitates the internal microclimate of a natural salt cave or the natural state of the coast with a mild sea breeze on dry and sunny days. The salt room creates a unique atmosphere away from the hustle and bustle of everyday life and has an overwhelming antidepressant effect. "Salt dust" is another name for dry salt aerosol, which refers to the assembly of dry salt particles that reach a certain concentration and have a particle size of less than 2.5 microns. They can reach the parts damaged by PM2.5 smoothly, and use the characteristics of salt to repair the affected parts safely and efficiently through deep adhesion, sterilization and desilting, mucus wrapping, and promotion of expectoration. At the same time, under the action of dry salt particles, the phagocytic activity of macrophages is greatly improved, and the two together effectively resolve and repair the deposition deep in the respiratory system. Stimulated by salt particles, mucus secretion in the respiratory tract is enhanced to wrap the excreted matter; the cilia in the respiratory tract vibrate faster, which promotes the rapid excretion of sputum. And through the action of dry salt particles, a certain immune mechanism is formed to protect the respiratory system and reduce the risk of injury.
