Saunas helping with any kind of detox is complete hocum.

Blood donations clearly do.

Microplastics and PFAS aren't synonyms however.

What isn't established is a dose dependant harm from PFAS. Some things are harmful in minute quantities to the point it doesn't matter if you have a lot or a little.

Lead has a clear dose response but a relatively low threshold for noticeable harm. It's not clear what PFAS curve will look like.

I won't restart the linear no threshold flame wars about radiation harm but let's just say it's not always intuitive.

There is plenty of evidence that sauna does in fact help with detox, specifically phthalates. It's not magic or some intrinsic property of sauna though, just sweat. https://pmc.ncbi.nlm.nih.gov/articles/PMC3504417/
