Delhi’s air pollution doesn’t affect only the lungs. Fine particulate matter, especially PM2.5, can enter deep into the respiratory system and trigger inflammation and oxidative stress.
How PM2.5 affects the body
- Lungs: Can irritate the airways, worsen asthma and increase the risk of respiratory infections.
- Heart: Long-term exposure is associated with increased cardiovascular stress and a higher risk of heart attack and stroke.
- Brain: PM2.5-related inflammation and blood-vessel damage may affect brain health and is being studied for links with cognitive decline and neurological problems.
- Blood vessels: Fine particles can contribute to inflammation and impaired blood-vessel function, which can affect circulation throughout the body.
Why is it called a “silent attack”?
The danger is that harmful exposure can happen without immediate, obvious symptoms. Repeated exposure over months or years can gradually increase health risks.
How to reduce exposure
- Check the AQI before spending extended time outdoors.
- Avoid strenuous outdoor exercise when pollution levels are very high.
- Keep windows closed during severe pollution episodes when practical.
- Use a properly fitted N95/N99 mask outdoors during high-pollution periods.
- Reduce indoor pollution sources such as smoking and unnecessary burning.
Important: PM2.5 is not literally “attacking” the heart or brain in a single event; the phrase describes the cumulative health effects of repeated exposure.
