The common causes of sneezing and runny nose when waking up every day are: allergic rhinitis, vasomotor rhinitis and acute rhinitis. 1. Allergic rhinitis: When waking up in the morning, due to the high amount of dust mites, dust and other allergenic substances in the air, patients will inhale these allergenic substances into the nasal cavity, which will trigger allergic rhinitis, which will lead to sneezing, runny nose, nasal congestion and other manifestations. 2. Vasomotor rhinitis: When getting up in the morning, vasomotor disorders may be caused by cold air stimulation indoors, resulting in vasodilatory rhinitis, which may lead to sneezing, nasal discharge, nasal congestion, itchy nose and other symptoms. 3. Acute rhinitis: If the disease starts acutely due to viral infection, it will lead to runny nose, sneezing and other discomforts when waking up in the morning, and some of the patients may have systemic symptoms such as fever, malaise, loss of appetite, etc., which can be relieved with the control of the disease. If you wake up every day with sneezing and runny nose, it is recommended that you go to the hospital in time for systematic examination and diagnosis to avoid aggravation of your condition.
