Health Effects of Environmental Factors in India

1.Air Pollution and Respiratory Ailments

There is much more in the air in India’s crowded cities than just a combination of oxygen and nitrogen. It transports a hazardous mixture of gases, volatile substances, and particulate debris that endangers the respiratory system seriously. There is an urgent need for quick attention and coordinated measures to mitigate the issue of air pollution and its attendant effects on respiratory conditions.

The Invisible Threat

Many Indian towns are engulfed in pollution, which causes them to be blanketed in gray fog, particularly in the winter. The primary culprits behind this scenario are fine particulate matter (PM2.5) and larger particulate matter (PM10) suspended in the air. These particles, often originating from vehicle emissions, industrial activities, and construction dust, are small enough to penetrate the respiratory system after inhalation.

Respiratory Ailments on the Rise

As these particles penetrate deep into the lungs, they cause health problems. The most immediate and noticeable effect is on the respiratory system. The incidence of asthma, chronic obstructive pulmonary disease (COPD), bronchitis and other lung conditions has increased in urban areas. Even in rural areas, where pollution may be less concentrated, the effects are felt, especially among those engaged in agriculture or living near industry.

Children and the Elderly

The harmful effects of air pollution are especially dangerous to children and the elderly. As their respiratory systems are still developing, children are more vulnerable to the harm that pollutants can do, and continuous exposure can result in serious health issues. The elderly are also more likely to require hospitalization due to poor air quality since they may have weakened immune systems and limited lung function.

The Link between Air Quality and Mortality

The dismal relationship between air quality and mortality rates has been highlighted by recent studies. High levels of air pollution have been associated with early deaths from heart diseases, strokes, some malignancies, and acute respiratory illnesses, in addition to other causes. The small particles can increase the risk of these fatal diseases by causing oxidative stress and inflammation in the cardiovascular system, together with gases like sulfur dioxide (SO2) and nitrogen dioxide (NO2).
