@chad thanks for all the great science in this and other podcasts. But concerning the benefits of saunas, let me say that it’s almost totally false that it grows more brain cells as your source might be claiming. I say this because there’s almost no evidence of neurogenesis in adult humans under any conditions, exercise or otherwise. We’re born with all the brain cells we die with (and lose a few on the way). We do see increases in connectivity and blood flow but that’s the brain using the resources it already has, not growing new neurons or glial cells.
Still gonna look into saunas for its other benefits though!
