Acclimatization is a whole thing. I remember thinking 65F / 18C was cold once upon a time, then I moved north and now only bother putting on a jacket if it’s below 40F / 5C or so (but now I start seriously suffering above 85F / 30 C where that used to be my ideal temp).
People who pretend certain temps are objectively not that cold or hot have never moved from one climate to another, I think. The person you replied to must be from a hot area.
But what can you do if your area climate includes 110+ F summers and below 0 winters? Besides moving, that is.
Yep. I lived in the middle East and SE Asia combined for around 12 years, and while occasionally it was too much, in general I loved the heat and rarely said “its too hot”, I moved back to the UK 3 years ago, in June. Hated it, was cold all the time. Now when it’s more than 25c / 77F on a calm and clear day I’m boiling and can’t sleep at night (barely anyone in the UK has ac at home).
