That's a topic I actually put a lot of thought, coming from South America living in Europe, I see an extreme contrast in shower habits. In the north of Brazil, people would take 2~3 "cold" showers a day--most people don't even have warm water, because it's over 30 degrees Celsius pretty much at any time of the day, at any time of the year, so you sweat a lot. Now here, I see people are mostly fine with 2~3 showers a week. Sometimes less. Initially that was a shock for me, until I understood it's a lot related to climate, job, activities, social life, etc, but also because in South America people rely more on the showers for their overall hygiene. They just shower for anything. Ate something too fatty that got your hands and face greasy? Time for shower. In Europe I see people taking more care of their hygiene other ways, like washing themselves, changing underclothes more often, etc.
