What environmental factors cause rhinitis?

Occupational environmental factors
Dust environment: In some specific working environments, such as construction, mining, flour processing, textile mills, etc., there are a large number of dust particles in the air. Long-term exposure to such an environment, dust will continue to stimulate the nasal mucosa, so that the barrier function of the nasal mucosa is damaged, causing inflammation, and then lead to rhinitis.
Chemical gas environment: Like chemical industry, electroplating, paint, plastics and other industries, there will be a variety of chemical gases in the working environment, such as benzene, toluene, xylene and other organic solvent volatile gases, as well as chlorine, ammonia and other irritating gases. These chemical gases are highly irritating and corrosive, which directly stimulate the nasal mucosa, destroy the normal structure and function of the mucosa, cause congestion and edema of the nasal mucosa, and increase the incidence of rhinitis.
High temperature and high humidity environment: in some high temperature and high humidity workplace, such as printing and dyeing factory, paper factory cooking workshop, hot spring bath, etc., nasal mucosa in a long-term high temperature and high humidity environment, blood vessels will be in a dilated state, mucosal tissue becomes relatively fragile, resistance decline, vulnerable to bacteria, viruses and other pathogens attack, thereby causing rhinitis.
Living environment factor
Damp living environment: If you live in a damp house, it is easy to breed mold, mites and other microorganisms. Mold spores and mites and their excreta are common allergens, and when people inhale these allergens, the nasal mucosa will have an allergic reaction, resulting in allergic rhinitis.
Poor indoor ventilation: in some indoor environments with poor ventilation conditions, such as rooms with long-term closed doors and Windows, basements, etc., the air can not be circulated in time, the concentration of carbon dioxide is increased, the oxygen content is relatively reduced, and various harmful gases and allergens can not be discharged in time, which will accumulate indoors, produce stimulation and damage to the nasal mucosa, and increase the risk of rhinitis.
Pet dander: Many families will keep pets, pet hair and dander will be dispersed in the air. For some people with allergies, these hair and dander are common allergens, which can easily cause allergic rhinitis.
