Maximum temperature predicted in Stockholm today: a refreshing 22°C.
In our Summers, we'd bump the Aircond temp up a degree or so above that, as we would start to shiver!
When I was a kid in the 1950s, anywhere that had Airconditioning would wind the temp down to near Arctic, just to show they could.
One "Movie Theatrette" was particularly savage in this.
People "in the know" who were sweltering at 38C plus outside would hurriedly pull on wooly jumpers (pullovers) & jackets in the foyer before entering.
Many years after that, I encountered its mirror image, when, in the UK, "rugged up to the eyes", I entered a Department store, which was heated to Oz Summer temperature levels.
