There Are those that really like sleeping at their ideal temp Who run ac more and those that seem to be “ok” using other means or I would guess just run “cooler”
My gf’s parents rented a house in Nantucket last year , it had A/c but we were on same floor as her mother who gets “cold” so after I laid it bed literally sweating for about an hour , I went to the basement where it was a perfect 65 and slept like a baby . That is really one of my very few pet peeves , I could sleep in a room that’s 40, just add blankets . I had a girlfriend that used to sleep with some sort of face covering because she froze lol but I only had on a bed sheet .
