Children should not swim during rhinitis because there are many chemicals inside the pool, such as copper sulfate, sodium hypochlorite, potassium aluminum sulfate, etc., which mainly play the role of disinfection and precipitation. These chemicals will stimulate the child’s nasal mucosa, aggravating nasal congestion, runny nose and sneezing, which is not conducive to recovery. It is best to wait until the rhinitis is well before going swimming. In the treatment of children’s rhinitis, you can spray local physiological sea saline to play the role of cleaning, and then spray the symptomatic treatment with mometasone furoate nasal spray to reduce the child’s clinical symptoms, you can also add appropriate anti-allergy drugs to reduce the symptoms of runny nose and itchy nose, commonly used is montelukast sodium tablets, after symptomatic treatment of children’s rhinitis in about 1 week can recover.
