Anecdotally, moving from India to North America really helped my health. I know this study is about long term effects but I believe even short term , it’s quite noticeable. It’s why I find it perplexing why so many people in the US want to do away with EPA regulations. Not only was pollution rampant in many Americans lifetimes, it’s completely observable how bad pollution is elsewhere in the world for people.
"While most things that clearly improve health are well known, one is insanely underrated: Fixing your air. I suspect this is often the most effective health intervention, period. Nothing else is so important while also being so easy to address."
