Just another thing that's only exists as a problem for idiots. As said already: you wash bedding separately and at 60°C, which you don't wash other clothes at. And few washing machines are big enough to effectively wash duvets with anything else.>!!<

I think all my socks and boxers say to wash them at 60. I think it's a common temp for towels too, if you follow the tag. I mostly wash everything at 40 nowadays.
Washing elastic clothes at 60C sounds like a bad time.
Washing sheets at 60C is important for sanitary reasons, though, it's not worth it to try to save electricity by washing sheets below 60C. Clothes are normally washed at 30-40C, so they must be washed separately from sheets.
I think boxer and sock elastics are made of sterner stuff since they're made to be washed at 60C and anecdotally they seem to take it without any issues with the elastics getting ruined. And I use them beyond what I think most would use them.
I don't throw them into the dryer though. I fear that'd ruin them faster.
