The Finnish cool-down method involves sitting in room-temperature air after the sauna so the heart rate drops naturally before any cold exposure is introduced, and research suggests this gradual transition supports better heart rate variability, more stable blood pressure, and longer-lasting improvements in blood vessel flexibility than jumping straight into cold water.Last Thursday I watched a guy at my gym finish his sauna session, sprint across the locker room, and drop himself into the ice bath like he was putting out a fire. He came up gasping, cursing, and looking... Read more...
Dry Sauna vs. Steam Room: What 20 Years of Finnish Data Taught Me About Heat

If your lungs can handle dry heat, that's the more evidence-backed choice for long-term systemic health.I spent three years thinking the dry-versus-steam debate was pointless. Both make you sweat buckets. Both leave you feeling relaxed. What's there to argue about?Then I came across a study that followed 2,315 middle-aged Finnish men for two decades. The ones hitting...
