Using the sauna after aerobic exercise improves VO₂ max more than training alone.
People who performed 30 minutes of cycling and then sat in a sauna for ~15 minutes afterward saw greater gains in their VO₂ max after 8 weeks of training compared to those who did the workout without sauna.
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.
The sauna has several health benefits. But it's also a powerful tool to amplify the body's adaptations to both endurance and strength training.
