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 day, I feel like trash if I even skip one day.
Tho honestly I often wonder if twice a day is optimal. I always feel great the few times I take it twice, but when I only take it once, I always wake up wanting to shower immediately to get the oil off.
