Swimming is not good for coughing. Coughing is a common clinical manifestation with many causes, so when coughing occurs, you should take rest and actively treat it accordingly. If the cough is triggered by a respiratory tract infection, swimming can easily lead to cold symptoms, which can aggravate the cough, and some patients with post-cold cough can also have a significantly worse cough at this time. It can also be seen in patients with cough variant asthma, where the airways are more sensitive and contact with cold water during swimming can trigger spasms in the airways and aggravate the cough. Some patients with chronic underlying lung diseases such as bronchial asthma and chronic obstructive pulmonary disease may have clinical symptoms such as chest tightness and shortness of breath if they go swimming again, and some patients may even develop lower respiratory tract infections due to the cold.
