Curiosity only.
Here in Brazil it’s very common to have several showers a day. I, for example, take two. The first is when I wake up, before I go to work, and the second is when I get home from work. I wake up at 6.30am and get home at 8pm.
edit: I said bath, but I meant shower.
Yes, the actual difference doesn’t concern the climate, whether it’s cold or hot, it’s simply cultural. In Germany, is it common for all Germans to adopt the same bathing posture or does it depend on the region?
It mainly depends on the season. Southern Germany may have more sun hours and slightly warmer climate, but not enough to take effect on the showering schedule. Some people shower every day nevermind the weather, but I would say every 2-3 days is standard. In summer or after workout it may be everyday or even twice, but nothing comparable to brazilian climate. Of course people have jobs where they get dirty, but that’s another topic.
