Back in my day nobody had air conditioning
Ditto.
But the houses were built for it.
- Southern California had thick Adobe walls, vaulted ceilings, and cold tiles floors.
- South Carolina had raised houses, verandas, porches, breezeways, fans.
- Farm Country Illinois had farmhouses with the little tiny rooms blocked off to insulate the big breezy rooms (opposite in winter, snug as a bug, practical to the Nth, farmhouses), and wide shady veranda like porches, cool cellars.
- SE Asia (jungle) were built in the tropical style; low/flat/wide with cool tatami or cold thick wood/tile floors (and beds laid upon them!) with sliding doors/walls, to catch every breeze, and ceiling gaps to let all the rising heat out, so the breezes stayed but the heat left.
- Middle East had SoCal Adobe-like (mud brick of some kind) day spaces, and flat roofs to sleep on, or built around interior shaded planted courtyards blowing cold mist to bedrooms/living spaces open to them.
- Southern Italy used thick cold stone (or stone lined rubble fill) and vaulted ceilings and courtyards, free water everywhere
Living in the PNW the past few days has been like being the kid who lost the coin toss and had to go fetch the whatever from the shed... hotter than hell, soaked sweaty the moment the blast of hot air hits as the door opened, worse inside, dirty, choking dry throat, gritty eyes, scalded hands.

I’d all but FORGOTTEN about that, until this week. 10-25 degrees hotter IN than out.
