Help, I have recently moved into a rented house which has its bathroom in the North. Worse still is that none of the windows open and there is a tiny vent in one window and no extractor fan. Since we moved here, I have been plagued with all kinds of head/facial illnesses, mouth ulcers, sinusitis, headaches, sore throat etc etc. I have moved most of the plants in here in order to soak up some of the dampness, I have placed a bowl of sea salt on the floor but nothing is helping.
