The most common cause of sneezing and itchy nose every morning is caused by allergic rhinitis. Because allergic rhinitis is exposed to dust mites in the air in the morning, and the dust that falls overnight will accumulate too many dust mites when you wake up in the morning, stimulating the nasal cavity causing sneezing and itchy nose, and also the clinical symptoms of nasal congestion and runny nose. Treatment plan: It is best to clean the dust mites on the bed with a vacuum cleaner when you go to sleep, and have your family members open and ventilate the windows when you get up in the morning, and then clean the bedding to reduce the symptoms of irritation. If it is very serious, you can use the nasal spray drug Nesuna and the oral drug Olopatadine.
