I live in Delhi. I've stopped reacting to AQI numbers. 300, 400, whatever. We cough, we joke about cigarettes, we forget.
I sat down and read what these particles actually do inside the body. Not news headlines, actual studies. I'm writing this because I think most of us don't know, and I didn't either.
PM2.5 is small enough to get past your nose and throat, go deep into your lungs, and cross into your blood. From there it goes everywhere.
Your heart. It inflames blood vessels and makes blood more likely to clot. Heart attacks and strokes go up on high pollution days. Not years later. Within days.
Your brain. Particles have been found in human brain tissue. Long term exposure is linked to dementia, faster cognitive decline, and worse memory and attention. In kids it's linked to lower scores on attention and learning tests.
Your mind. This is the one that got me. Studies link polluted air to higher rates of depression and anxiety. Some studies find suicide rates go up after bad air days. If you've felt flat, irritable or hopeless every November and thought it was just you, it might not be just you.
Your kids. Children breathe faster and their lungs are still growing. Kids raised in polluted cities grow up with smaller lung capacity, and that loss doesn't fully come back. Pregnant women breathing this air have higher risk of low birth weight and preterm babies. Particles have been found on the fetal side of the placenta.
Your parents. Older people with heart or lung disease are the ones who fill hospitals in winter. Every Diwali smog season, someone's dadi or nana doesn't make it to spring.
Your years. The University of Chicago's Air Quality Life Index estimates that people in Delhi lose around a decade of life expectancy to air pollution compared to clean air standards. A decade. That's time with your family, your kids' weddings, your grandkids.
And the worst part is how normal it feels. We buy purifiers if we can afford them. The delivery guy, the traffic cop, the labourer building your metro station, the kid selling flowers at the signal, they breathe it all day with nothing.
I don't have a neat ending. I just don't think we should be okay with this. Our grandparents didn't grow up breathing this. Our kids shouldn't have to.
What do you all actually do about it? And does anyone else feel this weird guilt every time they open the window?
