It can be definitively said that smoking is prohibited for those suffering from acute bronchitis. Common symptoms of acute bronchitis include coughing and expectoration, and some patients may experience chest tightness and wheezing. Smoking can trigger or exacerbate these symptoms. Firstly, the smoke and heat from smoking can directly damage the mucous membranes of the respiratory tract, triggering or worsening symptoms such as coughing and asthma. Additionally, the harmful substances in smoke can also irritate and damage the respiratory tract mucous membranes, exacerbating these symptoms. Therefore, patients with acute bronchitis should quit smoking.
