Does a sauna boost muscle growth?

What’s the deal with saunas and muscle growth? Some swear by a post-workout sauna session, while others think it’s just a fancy way to relax.

Like most things, the truth is somewhere in the middle.

Sauna use isn’t just about unwinding; it might actually give your muscles a boost. The heat ramps up growth hormone levels, improves blood flow, and triggers heat shock proteins—key players in muscle repair and recovery. Pair that with a solid workout, and you’re looking at better nutrient delivery, reduced soreness, and faster gains.

But is it magic? Not quite. The science is promising, but it’s not a slam dunk yet. Critics say we need bigger, better studies to fully understand how saunas stack up against other recovery methods, like cryotherapy. Still, if you’re looking for an edge, a sauna session could be a solid addition to your routine—especially when combined with other strategies.

Bottom line? Saunas aren’t a quick fix, but they might just be a secret weapon in your muscle-building arsenal.
