Humans generate (some) humidity, as we exhale some water vapor. There are other possible sources, as well, such as gas burners, cooking processes that emit steam, showering, humidifiers, etc.
The humidity level is low and staying low inside because the outside air (apparently) is cold, and heating cold air lowers the relative humidity as warm air can hold more water vapor than cold air. Apparently your air exchange is enough that the indoor humidity is stabilizing at around 30% or so, I guess. If you had no air exchange at all the humidity would rise, eventually at least, but there are significant drawbacks to a lack of air exchange.
