A couple days without a shower is healthier for your skin than every day, unless you are stinky or have something filthy on you like mud or worse. Sweaty skin has to be rinsed, but not scrubbed, and mild amounts of soap do the job. It's really ok to sweat. Sweat doesn't stink. I sweat like crazy at the gym, but because I take a multivitamin with lots of zinc and magnesium I barely smell at all. I do shower after, but I try to not be in the chlorinated water for long. That stuff we pipe into our houses is almost dangerous with all the chemicals they dump in it. Antiperspirant actually hurts your skin. It's ok to sweat. A lot of the lotions and soaps we use do damage too. If I'm now sweaty or stinky, I don't shower that day. I have a lot more acne when I shower daily.
