[They have] an aroma... It's not an unpleasant smell, per se, but it's a smell
My knee-jerk reaction was that I don't want to have "an aroma", but I think it's a valid question whether our current society is a bit too overhygienic. Eg. washing clothes too often is going to just wear them out faster, meaning more resources wasted on new clothes
If you're working out in those pants and they don't smell like vinegar after 4-5 uses without washing it means your sweat salt concentration is high enough to keep odor-causing bacteria at bay. Which is basically normal 👍
If you get headaches after working out though or experience vertigo then you're losing too much salt and should down some electrolyte solution (e.g. Gatorade) instead of just water.
No aroma trick used by stage actors who couldn't wash costumes in between performances: vodka in a spray bottle. I've tried it for jeans and can confirm it 100% removes odors. I wash my clothes, but it is a great "emergency" solution for laundry day. The vodka dries very quickly and you're on your way.
I don't wash jeans that often and i air things which don't get smelly so fast over night, like linen shirts. But my t-shirts or underwear are smelly after one day.
And no, i don't want no aroma on my pants!
Those are the things that should be washed regularly and hot washed. Undies protect the rest of our clothes from all the ick. The hot can degrade the elastic but replacing a band isn't too difficult.
Honestly most fabrics shouldn't be washed as regularly as mainstream western society insists. a lot of fabrics are warm to cool wash only, shouldn't be tumble dried, and should be hung insideout or in the shade. Your clothes will last sooooo much longer if you take care of them
Bamboo is marketed as this tough "green" fibre and if we ignore the processing it takes to turn such a woody fibre into a shoft fabric it can be long lasting with proper care. It doesn't like hot washes or tumble drying. It breaks down the fibres and negates the durability that's being marketed. Denim is something that should be rarely washed and preferably just cool soaked and swished and rinsed (like a rug or curtains) then dried on a line insideout to prevent fading.
So I guess I would probably be one of the people this article is discussing but all's I'm really doing is following proper fabric care practices
