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.
A bit of both. It dries out your skin to shower every day, and I honestly don’t feel like I need to shower every day with not-particularly-active lifestyle. Saves water and electric, as well, but not enough for that to be the reason why.
