To my understanding, while sweating is important to heat adaptation and blood plasma volume adaptations, thermal load and cardiovascular strain are likely bigger factors (and more important for the health benefits mentioned in this study). Overall thermal load is still higher in a hotter dry sauna than in a steam room

That's not my understanding, but my understanding is somehwere between 3rd and 6th hand, so it's likely not worth much.
