Sneezing is not necessarily a cold. Sneezing is related to external stimulation of the nasopharynx and is a nasal allergic reaction. Some people sneeze when they encounter cold air or irritating smells, or even a runny nose. If there is no other discomfort, it should not be a big problem and no special treatment is needed. Some children with chronic pharyngitis, rhinitis, bronchial asthma, and cough-degenerative asthma are prone to sneezing, and sneezing caused by a cold can disappear with treatment. Frequent sneezing or allergic symptoms such as runny nose and nasal congestion are caused by allergic factors. Physiological sneezing is a normal phenomenon. The common symptoms of cold include sneezing, runny nose, body aches and pains, fever, chills, strong pains in the head and neck, coughing, coughing up phlegm, and loss of appetite.
