Acute bronchitis has a relatively rapid onset and occurs fairly frequently. It typically causes clinical symptoms such as fever, cough, sputum, shortness of breath, and wheezing. During an acute episode of bronchitis with fever, it is generally not advisable to engage in strenuous exercise, as the body’s ability to dissipate heat is already compromised due to the fever. Continuing to exercise might lead to a rapid increase in body temperature because intense physical activity enhances heat production while the cooling functions are relatively diminished. Therefore, it is not recommended to exercise during the feverish phase of acute bronchitis. Exercise can be considered when the body temperature returns to normal and other clinical symptoms have significantly improved.
