Air pollution can significantly affect heart health by introducing harmful pollutants into the bloodstream. When inhaled, fine particulate matter (PM2.5), nitrogen dioxide, ozone, and other pollutants from vehicles, factories, and industrial sources can penetrate the respiratory system and enter the circulatory system. These pollutants can cause inflammation in blood vessels, promote plaque build-up, and lead to the hardening of arteries (atherosclerosis), increasing the risk of heart attacks and strokes. Over time, exposure to polluted air can elevate blood pressure, exacerbate arrhythmias, and impair heart rate variability, which is vital for heart health. Additionally, air pollution is linked to oxidative stress, where free radicals damage cells and tissues, further straining cardiovascular function. People with preexisting heart conditions, children, and the elderly are particularly vulnerable to the adverse effects of air pollution on the heart. Below we discuss some ways in which you can protect your heart from air pollution.
Monitor air quality indexes (AQI) and try to stay indoors on days when pollution levels are high. Limiting outdoor activities reduces exposure to harmful particles that can stress the heart and arteries.
Physical activity is essential for heart health, but during days with high pollution, consider shifting your workout indoors. Use well-ventilated spaces or air-purified rooms to avoid inhaling polluted air that can negate the benefits of exercise.
Invest in a high-quality air purifier with a HEPA filter for your home, especially in bedrooms and living areas. Purifiers help reduce indoor pollutants and improve air quality, protecting your cardiovascular system from prolonged exposure to airborne toxins.
Planting trees and shrubs around your house can help filter out particulate matter and improve air quality. Certain plants, like peace lilies and spider plants, can absorb indoor pollutants, creating a cleaner, healthier environment.
Avoid opening windows during rush hours or when pollution is at its peak, especially if you live in urban or high-traffic areas. This prevents outdoor pollutants from entering your home and affecting your indoor air quality.
When going out on high-pollution days, wearing a mask with N95 or similar filtration can help reduce inhalation of particulate matter and pollutants that can harm heart health. Masks can be especially beneficial in congested or industrial areas.
Drinking water regularly helps your body flush out toxins, including those from pollution. Adequate hydration supports the kidneys and liver in processing pollutants, reducing oxidative stress on your heart and vascular system.
Foods high in antioxidants, such as berries, nuts, and leafy greens, combat oxidative stress caused by pollution. These nutrients support cardiovascular health by neutralising free radicals that can damage blood vessels and heart tissue.
Omega-3 fatty acids, found in fish oil, flaxseed, and walnuts, have anti-inflammatory properties that can protect the heart from pollution-induced inflammation. Omega-3s support blood vessel function and can lower the risk of heart disease.
Implementing these practices can help mitigate the impact of air pollution on heart health, fostering a healthier environment for both you and your heart.

Danielle Wilhour, The ConversationDelhi Breathes Easy: 5 Pollution Hotspots Log 'Good' AQI For 1st Time In July
Reported by Ishika VermaA study led by the University of York has found that sectors like shipping, aviation, and construction face much weaker legal controls on nitrogen oxide emissions compared to home heating or cars.
If you are one of the 39 million Americans in the US living with migraines, there's a good chance an intense headache will begin when the weather shifts.
In a big shift for Delhi's air quality this monsoon, five of Delhi's 13 pollution hotspots recorded 'Good' Air Quality Index (AQI) readings on Thursday - a first for the month of July.
Air pollution may not only affect your heart and lungs but can also raise the possibility of developing meningioma -- a typically noncancerous brain tumour -- according to a study.
TEMPO, a collaborative space mission by NASA, NOAA, and the Smithsonian Astrophysical Observatory, is transforming air quality tracking across North America. Since 2023, it has delivered hourly, high-resolution pollution data from space, aiding researchers, health officials, and the public.

Friday December 20, 2024While some may argue that people in Delhi are now more aware of air pollution than they were a decade back, my rebuttal would be that awareness does not mean that people are concerned.
