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.
[For the sake of other commenters: OP likely meant washing oneself, regardless of immersion bath or not. It’s just that Portuguese “banho” can mean both “shower” and “bath”.]
From 4 to 12 times a week. If it’s mid-winter and I spent the whole day working (from home, no heavy labour), I might skip a shower day, never two in a row because that’s nasty. If it’s hot I’ll probably take a proper/cleaning shower every morning, plus a quick shower around 18:00. (I’m from Paraná.)
The cold in Paraná is a delight, right? Here in Rio de Janeiro, the cold is an illusion. I think I can go without a shower for a day, if I don’t have to leave the house and it’s freezing cold.
