Yep, you got that right. Go into any military gym, and probably 20-percent of folks will go for a 10-minute piece into the sauna, after their 50-minute work-out. I noticed that for years.
You can likely find similar statistics that show people who drink regular unsweetened ice tea instead of Pepsi or Coke...are less likely to be diabetics. But you’d get the same values if they just drunk spring water.
When I was a kid at my Grandparents (Finns), a sauna was an hour long over 200 F. 15 minutes in 5 minutes out (or however long it took the adults to drink a beer) times 3.
Females went first and refired the stove before the males went.
