74F in the winter. In the summer I usually leave the A/C off and use fans, but if it gets above 90F I'll let it run for a few hours before bed.

I seriously don't understand how people farther north of me survive the cold. And I live in Atlanta, so there's a lot of them.

some people in my family have sensory things where they feel slightly hotter than others. 69f for most of the year, in winter we hardly use the heater since it doesn't freeze where we live, but my room doesn't have full insulation since the garage is below it, so I have a little bathroom heater in winter.

If it was up to me probs ~71.

80 in summer during the day, 75 at night, 78 day and night in winter. We do not have heat, and 78 is required for the air conditioning to run periodically in winter to dehumidify the house.

Florida keys

During the cold season
20°C, 18°C at night and when away

During the warm season
23°C, 25°C when away

Year long lowest possible to keep whatever fluids are in the radiators flowing. Not off but not too on either. And then open windows to regulate temperature.

My building is hot OK...

AC only goes on when it's 90 out. Used it 5 times last year. People can adapt. It's like cutting sugar from your diet.

When I visit the US I find that I usually set it in the mid to high 60s for optimal comfort.

I'm originally from Florida, so 78 is what I usually leave mine at during summer.

23 in winter and 22 in summer. Nights are set at 18 all year long.

23 all year round

Not American so we turn the heat on when it’s cold and off when we’ve warmed up enough to save money.

78 is insane, only a few C off the highest temp ever recorded in my country.

I set mine to 0π at night and in the summer, and ^3^/~2~π to ^11^/~6~π in the winter... the numbers have worn off and idk what the actual temp is, but I do know all of them are in Quadrant IV.

*I only open the window or curtains at night in the summer or maybe sometimes when it's raining in the winter. I think my dream house is literally a cave.

68, but now the weathers nice enough that I don't need to use it

78

My wife likes us to suffer....

I agree that 78°F is way too high to be a confortable sleeping temp, though being in a country where residential AC isn't really a thing and inside temps at night often are higher than that in summer... you get used to it, it'll just never be fun.

My ideal sleeping temp is like 15°C but even if I had AC that seems too wasteful so I'd probably settle for 18-20

I acclimate to to the heat. I've lived in the South with no AC at all; 80F with humidity control is cushy by comparison.

Summer: open windows until heat and/or humidity causes concern for my electronics.

Winter Day: 68F Winter Night: 58F

Upstate NY - 64°F in the winter, no A/C ( just a half-assed whole house fan).

Why would I care what temperature it is when I'm sleeping? I'm asleep.

That aside, 60 winter and 73 summer.
