This is an expected result of the massive skin vasodilation and the reversed temperature gradient, which directs most of the blood towards the skin to maintain a normal core temperature.
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.
Both raise systolic blood pressure during exposure; values usually drop below baseline within 30 min.
So, while it might take longer for someone who's coming from a place of hypertension to get to a place of normal blood pressure, like the fact that there's actually a response this quickly is really encouraging for the idea of sauna being a relatively quick treatment for elevated blood pressures.
And the heat is causing different chemical changes in your body. So you're increasing nitrous nitrous oxide production in your vessels, which is forcing your blood vessels to dilate. So you're getting like it's almost like working out your blood vessels. they're they're um they're dilating. They're contracting back when you get out of the sauna. You're getting sort of this this work out of your blood vessels which helps reduce blood pressure.
But the the fact that we saw this after seven sessions is like is pretty awesome actually because it really suggests that the the actual like dose happens relatively quickly.
A single sauna session lowers blood pressure
these results are in line with several studies that have shown sauna use lowers blood pressure.
In addition to exercise, using the sauna or hot baths is one of the best lifestyle interventions to improve blood pressure.
Sauna use improves vascular health and blood pressure - both interventional and observational studies support this.
And one of the most important is the blood pressure because sauna use, long-term sauna use, can decrease blood pressure level.
There's there's um I mean there has been you know some evidence on on sauna improving blood pressure but there's a lot of literature out there on on hot baths and he's doing it totally I mean it's probably a lot more robust in in a way as well.
Yeah. There's there's um I mean there has been you know some evidence on on sauna improving blood pressure but there's a lot of literature out there on on hot baths and he's doing it totally I mean it's probably a lot more robust
There have been intervention trials as well showing that if you expose people to even just a single sauna session but multiple sauna sessions they improve their blood pressure after using the sauna even after a single sauna session.
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.
