In this particular season of spring, people are susceptible to foreign bodies, inflammation, and physical irritation, which can trigger a cough.
Cough is a common respiratory symptom, the main reason for its occurrence is that the trachea, bronchial mucosa or pleura of the respiratory tract has been subjected to inflammation, foreign body, physical or chemical stimulation, which triggers a series of changes in the vocal folds, respiratory muscles, and intrapulmonary pressure, and then a symptom occurs.
1. Inhalation of foreign bodies causes allergic cough. In spring, the most common inhalants are pollen, dust mites and animal dander, etc. These foreign bodies enter the human respiratory tract and stimulate the airway to produce an allergic reaction, resulting in coughing and even asthma.
2. Infection-induced cough. In spring, the human body’s immunity fluctuates, and people with weak immunity are easily infected by bacteria, viruses and other pathogens, resulting in inflammatory reactions in the upper respiratory tract, and then cough symptoms.
3. Physical stimulation induces cough. Spring is the time of transition between cold and spring, inhalation of cold air can stimulate the airway, thus inducing cough.
In addition to the above factors, exercise, special diets, and medications can all induce coughs of varying degrees of severity. If you have a cough in spring, it is recommended that you seek medical attention to determine the cause of the cough.
