Wow. 74 in the bedroom. I'd be roasting.
Tell me about it.
I have the habit of sleeping with a small table fan on the nightstand to blow air over my face. I need it to sleep in the summer, and this habit carries over to the winter. I tried a noise generator to mimic the sound of the fan, but it does not work well.
My personal fan causes a draft over to my wife's side, and it drives her crazy because she's cold all the time. So, I try to position the fan to minimize it.
During travel, of course I do not have this fan. It would take me a few nights to learn to sleep without it. Upon returning home, I went for a week without the fan. Then, turned it on in a sleepless night, and the habit came back.
It was 53F inside the house when I woke up this morning. I wore 3 sweatshirts over a t-shirt. No heat used.
Up at my high-country boondocks home, we would retreat into the bedroom and keep warm with a portable heater. When the outside is subzero, the 1.5-kW heater runs constantly to keep 60F. We have an electric blanket, and that helps a lot.
The house thermostat is kept at 45F, whether we are there or not. In the morning, I would dress up and go out to drink coffee waiting for the sun to come up. The home has very large windows on the south side looking down a hill slope. At the end of the day, the interior is often heated by sunlight to more than 70F.
The first few winters we bought this new home, we spent many nights there for the experience. After a few snowstorms, decided we knew enough, and have not spent much time there in the winter.
