If children have allergic rhinitis, they should not swim, mainly for the following reasons: First, once children with allergic rhinitis swim during the swimming, swimming water into the nasal cavity, easily induced infection in the nasal cavity, patients may develop sinusitis and other related diseases, swimming water into the nasal cavity can easily lead to choking and coughing and other discomfort, but also easily induced pharyngitis, bronchitis and other related diseases. Secondly, swimming water contains allergens, and once this substance is inhaled by the patient’s nasal cavity, it may also become one of the reasons for the onset of allergic rhinitis, leading to the aggravation of the patient’s allergic rhinitis and making the condition not easy to recover. If the swimming water chokes into the trachea, it also tends to induce bronchial asthma, cough and other related symptoms in patients. For children, swimming during an allergic rhinitis attack is not recommended and it is best to consider swimming after the allergic rhinitis has been completely cured.
