Idea for December 2025: lüften
My idea of the month is lüften.
This is the German practice of opening all the windows for a few minutes every day, to let the fresh air through.
Very good for stopping damp and mould, and generally for invigorating everything. Particularly in midwinter.
And apparently Kirstie Allsopp, the television property expert, is a keen exponent.
I like the idea literally and – even more – metaphorically.
