Allergic rhinitis is the main clinical term for allergic rhinitis when it strikes after waking up. The main reasons for this are as follows: 1. Most patients with allergic rhinitis are allergic to dust mites on the bed linen, and after waking up, the dust mites on the bed linen float rapidly in the air due to lifting the covers, moving the body and so on. After waking up, the patient’s respiratory rate increases, leading to increased nerve excitability in the nasal cavity, which also indirectly triggers the onset of rhinitis. In conclusion, most episodes of rhinitis after waking up indicate that the patient usually has allergic rhinitis, and it is usually advisable to use some nasal spray hormones, as well as antihistamine nasal sprays, and oral anti-allergy medication if necessary.
