Tracheitis is primarily caused by the decrease in our body's resistance, followed by infections from various external pathogens such as bacteria and viruses, manifesting mainly with symptoms of cough, phlegm, fever, and wheezing. Since tobacco can produce a large amount of smoke, which is an irritant to the trachea, it can induce symptoms like cough, phlegm, and even chest tightness and wheezing in patients. Thus, for patients suffering from tracheitis, smoking might exacerbate their condition, worsening the existing illness. Therefore, we advise patients with tracheitis to avoid smoking and to stay in environments with fresh, clean air as such conditions are beneficial for recovery.
