It is more common to have a runny nose every morning because of allergic rhinitis. When you get up in the morning, it is possible that the weather is cooler, and the dust that has been dormant all night will break out, causing allergic symptoms in the nose, along with sneezing and nasal congestion and itching. In this case, try to get friends or relatives to open the windows of your home every morning to ventilate and clean the dust. Put on your own clothes and go to another room, wait for the sleeping room to be cleaned and then come back to live and live.
