I agree, and there are studies on the amount of showers we can take. I, for example, work sitting down and with the air conditioning on. The problem is travelling from my home to work. It's impossible not to arrive at work very sweaty. An extremely crowded train/bus or just walking for five minutes is enough to make you sweat a lot.
Your comment is important. Many people from tropical climates think that people who don't take many showers a day are unhygienic. Just as many people from colder climates think that people who shower a lot are crazy.
Yes, the actual difference doesn't concern the climate, whether it's cold or hot, it's simply cultural. In Germany, is it common for all Germans to adopt the same bathing posture or does it depend on the region?
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.
Not shower, bath. Scrub all parts of the body with soap, shampoo, conditioner and post-bath deodorant. Women don't usually wash their hair every day here.
Here in Brazil, the wave of conservatism is very strong, mainly because it's linked to religion, "good customs" and the family. They suffer jokes, physical and psychological aggression and death. It may sound silly, but for these people it is a great victory to have a place where they can feel comfortable and not be afraid of dying.
In my case I wouldn't have any discomfort, it would just be a physical disability hahahaha
