How to address my humidity issues

I think that the first thing is to identify where exactly the damp coWhat happens to the damp air in the bathroom ank kitchen after showering and cooking?
All these matter plus we all give off "An individual person gives off about 400g (or 0.4 liters) of moisture per day through breathing and transpiration, which is equivalent to roughly 2.8 liters per week."

I have begun the experiment. Both rooms began at 73% humidity and 17.5 degrees. One room has windows closed and a small/tiny dehumidifier running. The other has window wide open and door shut. The first room is unchanged but the second room now has temperature of 16.4 degrees and 75% humidity.

ChatGPT tells that whilst this has reduced the dew point and there is less moisture in the air, it has also reduced the gap to the dew point (due to the temperature drop) and therefore increased mould risk. 

Keep it going, and use the ultimate result of whether it feels damp, or develops mould. 

Bear in mind that the first room has a dehumidifier running - although small - and the other one relies fully on nature. 

Things may well change overnight, where the wee dehumid cannot cope. 

This is brilliant - you have both temp and humid monitored. A great test! (Either way...)
