Wet Windows

[brat]

Probably just breathing and insufficient ventilation. Open the bedroom window in the morning after throwjng back the bedclothes so they can air.

You could open the door a crack or open the window the smallest amount overnight. But check other rooms early in the morning.

If there is a source of damp in the house such as a bathroom without good extraction, or wet washing draped around, fix it. Less often there is a tiny leak from a radiator or water pipe.

Water vapour is lighter than air so will rise within the house.

It's an old house, fitted with modern appliances so i don't think it's designed with all the upgrades in mind. We keep a small window open most nights but in winter we keep them closed so the problems arise from there. The trickle vents really helped cut down condensation and i understand have become mandatory in the last couple of years, so i wish i hadn't had new ones fitted before then.

I am guessing that you may be of 'the younger generation'.
Those of us 'of a certain age' ie over 50, tend to be used to sleeping cold. We were brought up in houses without central heating and would be the norm to find ice on the inside of a window in the morning.
We sleep with a window open all year around, even in winter and no c/h on at night, ever. Yes, we still get some condensation on some mornings but it's certainly not pouring off the windows.

Have the fireplaces been bricked up?

I remember when i was younger i used to take a car door with me onto the beach in summer....
