Mucus is a fluid that our body naturally produces to protect the respiratory system and prevent dust and germs from entering. But for some reason, when this mucus is produced in excess and accumulates in the sinus cavities of the chest and head, it causes severe discomfort. Here are the main reasons behind this:
Infections in the respiratory tract: When there are viral infections like colds and flu, or bacterial infections like bronchitis and pneumonia, the body produces excessive mucus to fight germs. This causes it to accumulate in the chest.
Sinusitis: When there is an infection or inflammation in the sinuses, which are the air cavities inside the bones of our face, the mucus does not go out and accumulates in the head. This can cause severe heaviness in the cheeks and forehead and headaches. This is commonly referred to as ‘head congestion’.
Allergies and air pollution: Allergies (Allergic Rhinitis) caused by inhaling dust particles, smoke, strong perfume odors, pet dander, and pollen can increase phlegm. More phlegm is produced as part of the body’s attempt to get rid of these allergens.
Chronic respiratory diseases (Asthma / COPD): People with asthma have constant inflammation in the airways, which causes excessive phlegm production. COPD, a condition in which lung capacity decreases in long-term smokers, is also a cause of chronic phlegm.
Cold foods and humid environments: Eating excessively cold drinks and ice cream can cause discomfort in the throat and airways and increase phlegm in some people. Similarly, sitting for a long time in humid rooms without proper ventilation can also increase phlegm.
