Respiratory health and mucosal immunity during autumn and winter

During the colder months, dry air from heating and cold outdoor temperatures can dehydrate the mucous membranes of the respiratory tract. This dehydration can impair the body's natural cleaning mechanism, where cilia move a thin layer of mucus to transport pathogens toward the throat.

Maintaining mucosal immunity is critical for defense against infections. A key component of this biological barrier is secretory immunoglobulin A (sIgA), an antibody produced by specialized plasma cells that neutralizes viruses and bacteria before they can attach to human cells. When the concentration of this antibody decreases, the body becomes more susceptible to infections.

Methods such as dry salt inhalation are used to support respiratory health. Fine salt particles can help liquefy thick mucus, making it easier to transport. Systems like the KLAFS SaltProX distribute microscopic natural stone salt particles into the air to assist this process. Combining salt inhalation with sauna use may also provide benefits, as the heat increases blood circulation while the salt aerosols support the respiratory tract.
