Coughing, a self-protection mechanism of the body designed to remove foreign bodies or secretions from the respiratory tract. However, many people often choose to be patient and not let the cough sound out of fear that it will affect their politeness or disturb others. This kind of behavior, although well-intentioned, hides health risks.
One study showed that forcibly suppressing a cough may not only worsen pre-existing respiratory conditions, but is more likely to trigger a pneumothorax — an urgent and potentially life-threatening condition in which air escapes into the space between the chest cavity and the lungs, causing the lungs to partially or completely collapse.
In-depth analysis: the link between cough and pneumothorax.
When people try to suppress coughing, the pressure in the chest increases dramatically, which can cause the alveoli to rupture, and air escapes into the pleural space. In this condition, the lungs do not expand properly, and respiratory function is severely affected.
Studies have shown that prolonged or severe coughing is a common trigger for pneumothorax. The risk is especially significant in individuals with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD) or asthma.
Precautionary measures. 
Proper coughing: Coughing should not be overly tolerated, and should be allowed to occur naturally to clear the respiratory tract of foreign bodies.
Medical Consultation: Persistent cough should seek medical help to identify an underlying health problem.
Enhance respiratory health: Strengthen the overall health of your lungs and respiratory system through moderate exercise and a healthy diet.
Risk identification: Identify signs that cough should not be ignored.
Coughing, the body's self-protection response, is often mistaken for a minor ailment. However, inappropriate coping, such as holding back a cough, can trigger serious consequences, and pneumothorax is one of them. Pneumothorax, in which air enters the pleural space, causing the lungs to partially or completely collapse, can be life-threatening if left untreated.
Key Signal: Persistent Cough: Prolonged or severe cough should cause alarm.
Chest pain: Sudden, severe pain, especially in one side of the chest.
Difficulty breathing: Feeling like you can't breathe in adequately.
Vocal changes: such as unusual noises, especially when inhaling deeply.
Knowing these signals can help us make the right judgment when coughing and avoid unnecessary risks.
Coping: How to properly manage cough and avoid pneumothorax.
Proper handling of cough will not only relieve discomfort but also prevent potentially serious consequences. Here are a few practical tips:
Cough in moderation: Avoid forbearance. A moderate cough can help clear respiratory secretions.
Maintain proper posture: Sitting up straight and coughing after taking a deep breath can help clear your airways more effectively.
Adequate hydration: Increase water intake to help thin phlegm and make it easier to pass.
Use a humidifier: Maintain indoor humidity to help relieve coughing.
Consult a professional: If the cough persists or is accompanied by the key signs listed above, seek medical attention promptly.
Cherish your breath and protect your health.
Coughing is the body's natural defense mechanism designed to clear foreign bodies and secretions from the respiratory tract. However, a prolonged or severe cough can be a warning sign from the body that it indicates a more serious health problem. From the above case studies, we learned that ignoring the dangers of coughing, especially holding cough, can lead to serious consequences such as pneumothorax. Therefore, in the face of persistent or severe cough, medical advice should be actively sought rather than relying on self-judgment and management.
