COST. People don’t have the money to spend installing aircon to save themselves from a couple of weeks of discomfort per year.
I don’t get it. How much do AC units cost in EU? I can buy one for, like, $200-300.
At the point there is a noticeable mortality spike, it’s not just a few weeks of discomfort eh?
and regulatory hurdles in many locations, you can't really install AC in many buildings because there's nowhere to put the external unit
