I have absolutely no professional expertise or experience, but in the 50s and 60s when we were kids, there was no central heating and mainly fossil fuels burnt within the house (wood, coal, coke, paraffin). So everything else being equal, we generated all the internal damp through heating, washing, cooking and breathing!
So, we had frosty patterns on the windows in the mornings in winter. We were made by our parents to open windows and to 'air' the house.
Since then, we have had developments in central heating and double glazing and draught excluding to the extent that we trap the moist air in our houses these days which is one cause of damp and mould.
For my part, whenever, Mrs J dries the washing inside the house, we have windows open everywhere. After a shower, (now I've fully insulated the bathroom), I leave the bathroom window and one other upstairs window so there is a passage of air to take the moist air out.
Friends, relatives and colleagues with similar modernish houses who don't take these precautions appear to end up with the symptoms of damp.
