Moisture in windows and frames

Definitely the humidifier.

In detached houses, furnaces have a humidifier attached to them. However there are 2 adjustments on them to control humidity changes in winter versus summer (one to regulate the winter/summer interior/exterior air return mix, and one to decrease the humidity % if the air return mix still isn't adjusted to the right humidity levels).

A way a detached house owner knows if the humidity % is correctly adjusted or not is to see if there is much in the way of humidity at the bottom of windows. The right balance is usually achieved when, on double-glazed windows, there is no humidity at the bottom when steam from cooking/showers/kettles/sinks/baths are not taking place, and that humidity on the bottom of windows just starts to form when the above does take place.

If you're getting humidity without any of the above cooking/showers/kettles/sinks/baths, then your place is too humid. Turn the humidifier off and see what happens. And also see if your body can adjust to the humidity (When coming from a warmer/more humid climate, it can sometimes take going through a year of seasons for you to be able to adjust).
