Patients who experience further exacerbation of rhinitis in winter often do so because the air is colder and drier in winter, which can easily cause stronger irritation to the nasal mucosa. Winter is also a period when respiratory viruses are more active and can easily be infected by respiratory bacteria and viruses among people, causing rhinitis to occur and even further aggravate. The use of air conditioning, floor heating and other heating equipment indoors for longer periods of time can also easily lead to excessive dryness of the air in the local space, or lead to a lack of water in the body, which may also have a degree of impact on the symptoms of rhinitis.
