Finland is a small country of just 5.3 million people, but over three million saunas(桑拿浴). 1. Finns have a sauna at least once a week. Saunas can be found all over Finland: in offices, factories, sports centres and hotel, and 2/3 of the people have one in their house.

Once the room is hot enough, the fire is allowed to die and the room is ventilated (使通风) by letting the smoke out through a hole in the ceiling. 4.
