Everyone loves to throw around the “23% endurance boost” from sauna.
But almost no one explains what that actually means.
It’s not more mileage.
It’s an increase in how long your body can tolerate effort before breaking down.
That’s a very different thing.
Sauna improves plasma volume, cardiovascular efficiency, and heat tolerance. The same systems you’re trying to build through endurance training.
The difference is you get that adaptation without adding mechanical stress to your joints and tissues.
Used correctly, it’s one of the most underutilized performance tools.
If you want to train smarter, not just harder, this is where sauna fits.
Don’t compromise health for performance.
