The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Sauna (dry). My toxin blood panel confirms sauna clears plastic related chemicals: BPA, phthalates, PFAS, flame retardants, pesticides. The plastic particles themselves are too big to sweat out directly. Heat may activate other clearance routes: bile flow through the liver, the cell's internal cleanup system, and the gut barrier.
The therapy we think most responsible for this reduction is sauna as it also eliminated most environmental toxins in my body, including those linked to various plastics (200 F, 20 min daily w/ ice on the boys).
Sauna has been really impressive in terms of like how dram dramatically. It removed all of those toxic chemicals in like a super short period of time.
So, sauna could be the most efficacious thing we've done to reduce toxins of all types.
There's some compelling evidence that multiple heavy metals (Genuis' BUS data) occur at significantly higher levels in sweat than urine or blood. BPA and persistant organic pollutants (DDT metabolites, PCBs etc.) have been found in sweat, as well.
And they're cleaner than a three-year-old. And the answer is sauna. There's these guys are sweating. So it's incredible our potential to detox.
How do they have less chemical toxicity, less gasoline additives, less jet fuel, less xylene, less phalates? How do they have less of that? Because yes, in their in their youth, that stuff didn't exist.
the infrared saunas do affect the sweating mechanisms like something to do with the penetration there you do sweat which is great because you actually do excrete things like BPA and phthalates and mercury and heavy metals and things like that from sweat
And so that's why it is very helpful, and many of us don't do enough of that sort of thing. And as has been pointed out, whether you're doing it through sweat and exercise or whether you're doing it through saunas, whether you're doing it through other mechanisms, yes, it's good to get.
4–7 sauna sessions per week, 20 minutes at 80°C+, reduce cardiovascular mortality risk by 40% over a decade.
Regular sauna use raises BDNF and improves verbal memory in older adults.
Sauna protocols only generate the longevity effect when sessions exceed 30 minutes.
Hot-tub bathing yields cardiovascular benefits comparable to traditional Finnish sauna at matched core-temp dose.
