"Who the heck needs a sauna in Andalusia? You have 40 °C outside." We often hear people say that, but actually, there is such a thing as winter here, too. Sometimes in the early mornings or late evenings, it can be below 10°C. Besides, particularly in winter, people like to come for active holidays, and if you don't get back from your excursion before sunset, you can be frozen to the bone. You shouldn't underestimate that high humidity and a sometimes fierce wind can make it seem much colder. And what could be better than sitting in the sauna after dark, with a good book, and gradually getting your body warmed up to normal body temperature?
