Slept in cold / Heat is if you pawn room is with a temperature not in the range of 14ºC-25ºC, even with all clothing that gives you protection to heat / cold, it doesn´t matter when you sleep, probably they sleep naked.
There are temperature vents next to all bedrooms doors.

So the temperature inside the rooms are near the same as the corridor
I also use one vent on the geothermal plants, so it doesn't explode on closed environment.
That was my poor base, now that I am rich, I changed lots of rooms and now the wiring is safe inside walls (less chance of exploding).
I failed several times, don´t be ashamed of learning with your mistakes, that idea of using vents and just regulate the corridor I saw here, I used to place on heater/cooler in each room!
