Yes, living in closed quarters in cold weather will cause condensation on the cold surfaces such as window frames and the like. The immediate thought is to keep everything closed up tight to keep the heat in and run the heater less. This the wrong thing to do.
This is not an Alpine only problem.
Breathing puts a lot of moisture in the air as does cooking and bathing. What you need to do is to be sure and crack open a window near the stove and run the vent fan when cooking. When bathing, we always, summer or winter, open the bathroom vent a bit while showering and as soon as you are completed, open the vent some more and run the fan on high for a short time. To help with the moisture problem, use a squeege to wipe down the shower and get rid of water that could evaporate.
When sleeping and it is damp, we will leave a roof vent cracked open a bit. The moist air from breathing is very warm and warm air will rise, so the vent will let it escape.
Sometimes we will crack open a window during the day and run a vent fan if we are having a lot of moisture problem. It is sort of trial and error method to get the right balance.
