Air pollution directly linked to increased dementia risk

Only so much you can do about ambient pollution in your city.

Looking carefully at your cooking situation is worthwhile though. Was horrified by the spike in readings from stuff like steak in a pan

Are there studies showing indoor air pollution from cooking in a residential setting is linked to dementia?

Not sure - it may very well be a different kind of pollution, but the raw PM2.5 values definitely look scary fast with any kind of "dry" cooking where you're browning anything

The raw PM2.5 values also skyrocket with just boiling tap water, on my Ikea Vindstyrka. Which makes me question how useful it is, presumably even with "dry" cooking a lot of meats and vegetables have water in them?

It's actually not been established (at least, to the best of my knowledge) that PM2.5 caused by water vapor is any less harmful than other types of PM2.5 particulates.

And sure, yes, it's just water and its entirely plausible that water based PM2.5 is completely harmless... but wouldn't it be good to know that for sure?
