I expect as I get older I'll probably have the heating on more than I currently do.
I've always been a person who feels the cold more than most other people, so I do like the living room to be nice and warm during the evening when all I'm doing is sitting and watching TV.
I eventually remove my outer fleece layer in the evening, usually when the room temperature hits 25° or so. Sometimes I even remove the inner fleece, but that's rare.
I will happily wear a fleece in a room where the temperature is 26° in the winter. But in summer I would only be wearing a t-shirt or a sleeveless top if it's that temperature inside - there's no way I would be putting a fleece on!
It very rarely gets as warm as 26° inside the house in the summer, it would only be a couple of days during an exceptionally hot heatwave (I think the last time was in 2022, when outdoor temperature was 38°)
Curiously, I need to wear gloves outdoors when I go out for a walk if the outdoor temperature is below 16°, as I have reynauds syndrome and the circulation in my fingers shuts down. But indoors my hands can cope with lower temperatures (though I do wear gloves when taking things out of the freezer).
Make of that what you will! I guess I'm a bit of an oddball! 😂
