Causes of runny nose
There are many reasons why people have a runny nose, specifically:
-  Due to cold: This is a common phenomenon when the weather changes seasons. Viruses attack the nose and throat, causing a runny nose. The initial symptom is clear nasal discharge, which gradually thickens after a few days, sometimes accompanied by a mild fever, sore throat, and stuffy nose. However, depending on each person's resistance, the disease will go away on its own after a few days.
 -  Due to flu: The disease is caused by the flu virus. In addition to the symptoms of a runny nose, the patient also has a high fever, sore throat, stuffy nose, etc. If the flu occurs in young children or the elderly, it can be dangerous due to a weak immune system.
 -  Allergies: If you come into contact with allergens such as pet hair, dust, pollen, etc., you may also experience a runny nose. This is a manifestation of the body's reaction as a way to fight harmful bacteria.
 -  Due to sinusitis: The sinuses in the nose become inflamed, swollen, and edematous, causing nasal congestion and mucus to accumulate and flow out.
 -  Vasomotor rhinitis: This is also a disease that causes you to have a runny nose due to many irritants such as polluted environment or eating spicy food.
 -  Due to tonsillitis: is a cause of runny nose, especially in children. 
 

Runny nose in children makes them tired, even causes ear infections, sore throats, etc.
