Preliminary evidence suggests that sauna use after resistance training may increase signaling molecules involved in muscle hypertrophy.

“And you mentioned the possible benefits of doing it after strength hypertrophy training, which makes sense for plausible mechanistic reasons, no official data there yet.”

“There is some limited evidence showing that sauna post-workout enhances cardiorespiratory fitness and markers of anabolic signaling.”

“There’s also emerging evidence for strength training, with studies showing greater increases in markers of anabolic signaling associated with muscle growth with post-exercise heat exposure.”

“there has been at least some preliminary evidence in one small study that people that gotten this on after the resistant train protocol increased signaling molecules that are involved in dol signaling molecules that involved in muscle hypertrophy”

“another area that using deliberate heat exposure could be beneficial is combining it with resistance training or even using it during perhaps an injury when you're not able to work out and I would say a lot of this evidence is preliminary and more needs to be done but going off the preliminary evidence and just knowing that there's benefits for cardiovascular health as well why wouldn't you”
