Pneumonia is not allowed to swim because swimming can aggravate the symptoms of pneumonia and is not conducive to recovery from pneumonia. Pneumonia is an acute disease, mostly refers to the acute inflammation of lung tissue, mostly caused by bacteria, mycoplasma, chlamydia, viruses, fungi, etc., with bacterial pneumonia being the most common. Clinical symptoms include chills, high fever, cough, sputum, chest pain, etc. Pneumonia is extremely taxing, especially when accompanied by high fever and coughing, coughing up pus and other symptoms. Swimming is a kind of aerobic exercise, which requires further depletion of the body’s energy in the process of swimming, which will be accompanied by an increase in the person’s heartbeat and breathing, and an increase in the burden on the heart and lungs, making symptoms such as coughing and coughing up sputum significantly worse. If the pneumonia has healed and has basically returned to a normal state, swimming can be done.
