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.
+ Combined sauna and HBOT increased my serum VEGF over 500% (now in upper normal range)
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.

HBOT and sauna boosted VEGF 19x in 9 months.
HBOT and sauna boosted VEGF 19x in 9 months.
+ Continued daily sauna for 70 more sessions (total 120), 12 additional HBOT sessions (total 140), and 53 IHHT sessions further boosted my VEGF from 420 pg/dL to its current level of 501 pg/dL.
In my case, the increase is attributed to HBOT and Sauna, both expected to improve vascular function and angiogenesis, aligning with observed improvements in my circulation and blood flow.
My morning routine boosted my VEGF by 22x, now top 1% of healthy individuals.
+ 68 additional HBOT sessions (total 128) with 50 initial sauna sessions increased my VEGF again by 5.6 more folds (64→ 420 pg/mL).
HBOT and sauna dramatically increased my VEGF levels
In my case, the increase is clearly linked to HBOT and Sauna, both of which are expected to improve vascular function and angiogenesis, and both have also shown functional improvement in my circulation and blood flow.
The second exciting result was a surge in VEF. This is the signal your body says, "Hey, make more blood vessels." ... But since doing sauna, I'd boosted it another 5x.
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.
