Rhinitis patients generally require humidity at about 50%, the specific humidity can be decided according to the state of the patient’s nasal mucosa, the right humidity is very effective for the prevention as well as treatment of rhinitis. If the humidity is too low or too high, it is not good for rhinitis, mainly the following analysis: 1. If the humidity is too high, that is, the air is too humid, humid air is more suitable for the growth of viruses and bacteria, viruses and bacteria multiply in the house and enter the nasal cavity, easily induce patients to appear rhinitis and other related performance, but also not conducive to the recovery of patients. Microorganisms in the air, such as dust mites, are particularly suitable for their proliferation when the humidity increases, and if inhaled by patients, they can easily induce allergic rhinitis. In short, too much humidity is not good for the recovery of rhinitis. 2, too little humidity is also not good for rhinitis, clinically it mainly refers to the air is too dry, such as in summer, autumn or to the desert and other areas, the air is too dry, resulting in the evaporation of moisture in the nasal cavity too fast, patients will generally appear dry nose, nose pain, even nose bleeding and other related uncomfortable symptoms, so the right humidity is very good for rhinitis .
