Every sauna guideline you have ever read was written for sea level. You do not live there.
At 8,000 feet the atmosphere runs about 74% of sea-level pressure — roughly a quarter less air in every breath. Add a Colorado winter, where the outdoor air is often drier than the desert, and you are losing water before the stove does anything at all.
— Drink before, not after. Once you are behind, you stay behind.
— Salt something. Water alone is not the whole answer up here.
— Shorter first rounds than the guides suggest, until you know how you personally handle it.
— Stand up slowly. Every time.
None of this is an argument against heat at altitude. The contrast between a 190-degree room and a Colorado night is better than anything you will find at sea level. It just asks for a little more attention, which is arguably the point of the whole ritual.
