Today we all went to Spanien, which is a municipal swimming pool and spa, right in the centre of town. The building is art deco and has hardly been altered. The pool is huge and overlooked by an enormous clock with hands the size of scaffold planks.

We had a quick splash before it was our allotted slot in the wellness centre - or Merchant Bath as it is sometimes called. This was on the top floor. Outside we could see snow-covered apartment blocks and parks. Inside was an immaculately clean, white tiled room, complete with steam rooms, saunas and plunge pools. They only let a certain number of people in at a particular time, so there was plenty of space to relax.

The amazing thing is that Daisy was allowed to use all the facilities. This is odd because in the UK she can’t use a jacuzzi until she’s eighteen.

At the end of our ninety minute slot, just after the girls went to get changed, I was joined in the sauna by just about everyone in the spa. Then a fitness instructor came in with a bucked full of ice. I don’t know what he was saying but he poured three glasses of ice onto the furnace, each pushing out a particular aroma, which he wafted throughout the room with a towel. Then he ladled ice onto our backs, one at a time. Very odd.

Outside, it was about minus three, which closed our pores pretty quickly.
