Hello, the causes of rhinitis:

1. Climate: When the climate changes significantly, sudden cold or heat occurs, which can easily irritate the nasal mucosa. This can lead to acute or chronic rhinitis, especially at the turn of the seasons.

2. Surrounding environment: The nasal mucosa is easily irritated and damaged due to the influence of the external environment, causing inflammation and leading to rhinitis. If the working or living environment is dry, dusty or polluted by harmful substances, the nasal cavity will also be exposed to this environment.

3. Bad living habits: Many people often have the bad habit of picking their noses, and it is now more popular to pluck out their nose hairs for the sake of appearance. However, they do not know that picking their noses and pulling out their nose hairs can easily cause damage to the nasal skin and hair follicles. The secondary cold can damage the tissues in the nose and cause nosebleeds.

4. Genetic factors: One of the factors that induce rhinitis is genetic factors. People with a family history of allergies are more susceptible to this disease. Most patients' families have a history of asthma, urticaria or drug allergies. In the past, such patients were called atopic individuals, and their ability to produce antibodies in their bodies was higher than that of normal people.

5. Systemic diseases: Patients suffering from systemic chronic diseases can cause long-term blood stasis or reflex congestion of the nasal mucosa, causing nasal lesions. In addition, lack of vitamins in the body or excessive smoking and drinking for a long time can lead to vasomotor dysfunction of the nasal mucosa, mucosal hypertrophy, and gland atrophy. Or suffering from hypothyroidism, pregnancy and other diseases, which can cause congestion and swelling of the nasal mucosa, leading to rhinitis.

7. Occupational and environmental factors: Occupational and environmental factors are one of the causes of rhinitis. Living in an environment stimulated by dust or chemicals for a long time, or working in an environment where the ambient temperature and humidity change rapidly, such an environment will damage the ciliary function of the nasal mucosa and induce nasal pathologies.
