Can rising air pollution increase your risk of pneumonia?

The National Capital is witnessing an alarming rise in the air pollution levels characterised by persistent, unbreathable air laden with smog. The overall air quality has again slipped into the ‘severe’ category despite light rainfall in the capital city. The national capital’s AQI stood at 339 at 6 am on Saturday, as per the data by the System of Air Quality and Weather Forecasting And Research (SAFAR).

 This unsettling phenomenon has now entrenched itself as an annual occurrence. The predicament extends beyond the confines of the outdoors, as the indoor air quality is equally pernicious.

And these combined factors are contributing to an alarming surge in respiratory issues, exacerbating pre-existing medical conditions, including life-threatening ailments such as pneumonia.

Air pollution looms as a formidable menace, one that not only jeopardises general health but can also inflict symptoms akin to asthma even in individuals previously untouched by such afflictions. Notably, pneumonia stands out as a particular ailment susceptible to exacerbation due to the abysmal air quality. Pneumonia, usually provoked by viral or bacterial agents, finds an unlikely ally in the form of the plummeting air quality and the myriad pollutants suspended in the atmosphere. These factors conspire to elevate inflammation levels within the lungs, posing a significant mortality risk if not addressed promptly. It is imperative to elucidate why this entanglement between air pollution and pneumonia demands our utmost vigilance.

So is air pollution and pneumonia linked?

Pneumonia stands as a formidable respiratory ailment, characterised by substantial risks to health. Its already ominous presence is further exacerbated when air pollution levels surge. Whether it be within the confines of our homes or in the great outdoors, scientific evidence unequivocally suggests that during periods of elevated pollution, the likelihood of contracting pneumonia and other severe respiratory afflictions doubles, significantly augmenting the specter of mortality.

Air pollution’s detrimental effects extend far beyond merely increasing the incidence of respiratory ailments and flu-like infections, which can serve as a precursor to pneumonia, particularly in vulnerable individuals. It also wields the power to compromise the body’s innate immune response. Exposure to various pollutants present in the air triggers substantial inflammation within the lungs and the respiratory tract, undermining the function of immune cells essential in the fight against pathogens and inflammation within this vital region. Furthermore, it disrupts the secretion of beneficial cytokines, critical in the body’s defense against infections.

In the face of elevated pollution levels, such as the current predicament we confront, the filtration mechanisms of the respiratory tract and airways are severely compromised. This diminished defense renders individuals more susceptible to the development of severe lower-respiratory infections, amplifying the gravity of the situation. The interplay between air pollution and pneumonia is a pressing concern that underscores the importance of proactively addressing this intricate web of health hazards.
