Environmental pollution and longevity: air pollution, noise, light, EMFs, & more (AMA 87 sneak peek)

The gist

1. Attia says sleep, exercise, and nutrition have far larger effects on longevity than most environmental factors, so fix those first.
2. Before acting on any environmental risk, Attia recommends asking how strong the evidence is, how serious the harm is, and whether it can realistically be reduced.
3. Studying environmental exposures is hard because people are rarely exposed to just one thing, making it nearly impossible to pin down what causes what.
4. The practical goal is not eliminating every exposure but finding a small number of high-impact, low-effort changes that deliver most of the benefit.
