Rhinitis is neither suitable for a humid environment nor a dry environment. Clinically, there are the following analyses: first, humid environment contains a large number of viruses, bacteria, microorganisms are inhaled by the human nasal cavity, it is easy to induce patients to develop rhinitis. Secondly, moist environment is easy to breed allergens, allergens are inhaled by the patient, it is very easy to induce patients to develop allergic rhinitis. Third, dry environment is not suitable for rhinitis, dry environment is easy to make the patient’s nasal cavity water evaporation fast, easy to induce the patient to appear dry rhinitis, easy to induce nasal mucosa dry, erosion, ulceration, and even bleeding risk. So for patients with rhinitis, neither a dry environment nor a humid environment is suitable. Clinical advice in a warm environment, pay attention to ventilation and air permeability of the environment, such an environment in the virus, bacteria is less, allergens are also less, the function of the patient’s nasal mucosa, but also has a certain protective effect.
