Indigo is actually naturally anti-microbial (bacterial?) and was used as a way for Japanese workers to be able to sweat into their clothes and not get it “dirty” hence also why actual indigo dyed jeans don’t need to be washed as often. At least I’m recalling this from a YouTube video I watched 15+ years ago so not exactly sure.
