Can Air Pollution Actually Make Me Sick Enough to be Hospitalised?

Vote: 1

A high level of air pollution may affect your lungs and cause respiratory problems if fine particles (e.g., PM2.5) and gaseous pollutants are elevated in the air. Aside from respiratory issues, high air pollution levels may also affect your cardiac health.


For people with underlying lung or health conditions, living or travelling in an area with higher air pollution levels may lead to medical conditions that require hospitalisation.


How Does Air Pollution Happen?


Air pollution occurs when air is contaminated with gases, particles, chemicals, etc. These are typically considered hazardous to health and the environment at high levels, and factories, vehicles, and sudden fire incidents are often the sources.


Some of the hazardous pollutants that may create health concerns are:



  • 5, which can easily penetrate deep into human lungs and mix in the bloodstream



  • PM10, Nitrogen dioxide (NO₂), Sulphur dioxide (SO₂)



  • Carbon monoxide



  • Smoke, dust, and debris from construction sites


According to the System of Air Quality and Weather Forecasting and Research (SAFAR), the Air Quality Index (AQI) measures the presence of pollutants in the air, and an AQI of up to 50 is considered good. However, in India, the average AQI level goes beyond 150 in major cities in early 2026. Such a high level of pollutant concentration may pose serious health risks.


How Air Pollution Impacts Your Health?


Now that you know that a higher pollutant concentration results in air pollution issues, you must know in detail how it affects your health:


1. Irritation or Inflammation of Airways


In a human lung, the respiratory tract is lined by a delicate membrane. As tiny pollutants can easily penetrate your lungs, even a couple of hours of exposure may lead to various issues. They include cough, a burning sensation in your throat, mucus accumulation, a feeling of tightness in your chest, etc. If these symptoms worsen, you may need immediate medical attention.


2. Worsens the Symptoms of Asthma


Individuals with underlying conditions like asthma are more susceptible as air pollution triggers Asthma attacks. As airways become sensitive, they often lead to reactions such as intense coughing, breathlessness, and chest heaviness. Due to higher AQI levels, emergency hospital visits may be required, especially for Asthma patients.


3. Increases the Chances of Heart Attacks and Strokes


As air pollutants increase inflammation and narrow blood vessels, they reduce oxygen levels, which may impact your heart or brain. Such a risk factor may lead to cardiac arrest or other cardiac events. As pollutants thicken your blood, they slow oxygen and blood flow to your brain, especially in the elderly. It may lead to strokes, which also require hospitalisation.


Final Word


High to severe pollutant concentrations in the air lead to air pollution and may impact your overall health. Children, the elderly, and people with underlying health conditions are more likely to fall sick, which requires hospitalisation.
