Continuous sneezing upon waking up in the morning, nasal congestion, severe heaviness above the eyes and eyebrows, and severe headaches when bending the head—this is one of the most common health problems among Malayalis. There are some air-filled cavities inside the bones of our skull. These are called sinuses. Severe phlegm is formed when the naturally occurring secretions (mucus) do not drain and become inflamed and infected. Scientifically, this is called sinusitis. Here are the 5 major scientific reasons behind this:
Allergies and Air Pollution (Allergic Rhinitis): The most important scientific reason for phlegm is allergies. When dust particles, smoke, pollen, and pet hair in the air are inhaled, the cells inside the nose become inflamed. This blocks the passageways to the sinus cavities and causes the natural mucus to build up inside the head instead of draining.
Viral and bacterial infections: The common cold is a viral infection. When you have a cold, excess mucus is produced in the nose and head. If this is not treated on time, bacteria can multiply in those cavities and the mucus can turn yellow or green, leading to a severe infection (Acute Bacterial Sinusitis).
Deviated Nasal Septum (DNS): In some people, the bone in the middle that divides the nose into two is bent to one side, either by birth or due to some injury. This is scientifically called a deviated nasal septum (DNS). Due to this bend, the airflow on one side is obstructed and mucus can easily build up in the sinus cavities of that area, leading to chronic phlegm.
Nasal Polyps: People with chronic allergies or asthma may develop small, grape-like growths on the skin of the nose and sinuses due to chronic inflammation. This is called nasal polyps. These growths can completely block the openings through which fluids from the sinuses drain and cause chronic headaches.
Cold Foods and Low Immunity (Lifestyle Factors): Excessive consumption of ice cream, cold water from the refrigerator, and cold drinks can quickly constrict the blood vessels in the nose and increase the density of phlegm in some people. In addition, a decrease in the body’s immune system, chronic mental stress, and living in a humid environment for a long time are also causes of increased phlegm.
