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.

I second this as a principle, though I have a hard time not showering once per day. It's a complicated balance, between not drying your skin with water and soap and not smelling.

I lived in Brazil for quite some time and, it being a huge country, I behaved differently depending if I was in a tropical or subtropical climate. I would mostly have one shower in the morning, except when it was mad hot and humid, when no matter how lightly you dressed, you'd still be drenched in sweat after a while

Come visit Brazil during summer, then we'll see if you keep that opinion.
