A recipe for the fastest trick to stop a severe cough is not true and lacks scientific basis. Cough is a self-protection measure of the human body, in the defense of respiratory tract infections is of great significance. However, coughing can also have a lot of harm, such as coughing will directly damage the respiratory epithelium, resulting in increased respiratory tract reactivity. There are many causes of cough, including allergenic irritation (e.g., dust mites, pollen, fungi, animal dander, etc.), infections (bacterial, viral, mycoplasma, etc.), foreign bodies in the airway, tumors, gastroesophageal reflux, cardiac insufficiency, cough-variant asthma, eosinophilic bronchiolitis, and upper airway cough syndrome. The treatment of cough needs to be based on the specific cause of the disease, and there is no so-called “fastest recipe”. If you have a severe cough, you should go to the hospital in time, complete the relevant examinations, and give targeted treatment and therapy after clarifying the cause of the disease.
