I was pleasantly surprised to learn so many people on social media were mindful of air quality, eg, in their homes, bedrooms, etc.

Air pollution: Cigarette Smoking Jr, but without the buzz.
I’ve just about always kept a HEPA air purifier in my bedroom because that’s the room I spend the most amount of time and do a lot of breathing. If that’s clean air… kinda like an oil change, right?
Depending on the size of your room, they are more or less expensive (eg, $120 for a unit that clears 100-175 ft2 vs. $430 for a unit that clears 280 ft2). And if you’re an actual smoker or live with one, there are special filters for that, too.
Many studies of a variety of designs suggest this to be prudent, at least.
Meta-analysis with bold conclusions: Effect of environmental air pollution on type 2 diabetes (Meo et al., 2015)
Results: Air pollution is a leading cause of insulin resistance and incidence of type 2 diabetes mellitus. The association between air pollution and diabetes is stronger for traffic associated pollutants, gaseous, nitrogen dioxide, tobacco smoke and particulate matter.
Conclusions: Exposure to air pollutants is significantly associated with increased risk of type 2 diabetes mellitus. It is suggested that, environmental protection officials must take high priority steps to minimize the air pollution, hence to decrease the incidence of type 2 diabetes mellitus.
scary, but correlation =/= causation yeah yeah yeah I know…
More mechanistic study in mice: Short term exposure to air pollution induces hypothalamic inflammation, leptin & insulin resistance, increased food intake, decreased energy expenditure, and obesity (Campolim et al., 2020).
