I think they’re equating to how when you brush your teeth at night you’re not eating for 8+ hours, leaving them clean that long. Similarly you’re not moving around and sweating while you sleep.

True but leaving food on your teeth while you sleep causes irreparable damage over time. not the case with having "dirty skin" while you sleep (most people still wash their hands/face before bed if they don't shower)
