I see all sorts of answers online, but am not fully convinced. I tried finding some research on the longevity of clothes between wash and wash + dry. Considering that it dries for hours just the mechanical movement should damage the clothes I would assume?
My dryer only has a low and a high setting and the length of time is human dictated.
I dry clean any really good clothing I own.
If I dry my clothes on high they are shrunk and sometimes ruined in other ways too.
Almost everything I own can survive the low setting with no noticeable negatives.
