How often do you wash your socks? An article on FiveThirtyEight caught my eye.
The article makes the case for washing your socks each time you wear them. I would agree if you're wearing cotton socks. I disagree if they are wool. I knit a lot of wool socks, and trust me, they do not need to be washed after a single wearing.
Recommendations for other clothing mentioned were; pajamas (3-4 wears); bras (2-3 wears); jeans (3 wears). I can live with that. Americans probably wash their clothes more often than necessary anyway because of the convenience of doing laundry.
As a child I remember tales of an old lady who wore her dress right side out for a week, then turned it wrong side out and wore it another week. I have known people who turned their sheets after a week and put the foot part of the sheets at the head. I do not do that.
Astronauts on the International Space Station have no means to wash their clothes. They wear socks, underwear, and exercise clothing a week and toss them. They wear shirts about two weeks and pants a month before tossing them. In weightlessness clothing doesn't cling to the body.
I think I pass the smell test so I'll just keep doing what I've been doing. How about you?
