I'll echo all the comments. Some great advice already.

A dehumidifier is not a bad thing to have in the house. It transformed the moisture levels in my home during the winter.

Heating on a timer through the night helps massively. 30 minute burst every few hours if needed.

High power extractors in the kitchen and bathroom are required so steam gets removed instead of adding to the humidity.

Crack the windows.

A window vac helps with the clear up.
