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.
Once a week, whether I need it or not.
It would be interesting to see how shower use correlates with water temperature. It feels like that correlation would be negative and usage of showers is premised on the existence of cheap energy, AKA fossil fuels.
I would suspect a correlation more with climate. If it’s temperate, you don’t shower as much as when you’re hot and sweaty all the time.
Also, geothermal power exists.
I was gonna say with the prevelance of air conditioning. In warmer places that have ample water supply but little AC, i would expect more showers as people sweat throughout the day and don’t want to be stinky.
I shower once a day in the morning, but i almost never sweat because im almost always in the AC.
Hot water is also a waste byproduct of nuclear power generation. There are whole towns that use nuclear heated water to warm their houses and for hot water. It’s used quite a bit in Russia and china already

Interesting! I didn’t know that, but it makes sense.
