I made the mistake of looking at /r/sauna on Reddit once or twice recently, and there was a lot of people doing very similar things.
"I take my preworkout, do my exercise, then I sit for 12 minutes at 90 degrees in sauna, before three minutes in the cold plunge-pool at 8 degrees, before going to sauna again for 19 minutes and I finish with a seven minute warm shower".
Just the thought of looking at a watch in a sauna, and timing things minute by minute sounded exhausting.
I assume going to sauna takes an hour, it might be I leave it on for a couple of hours, but beyond that the minutes inside/outside are a mystery and I like it like that. Same story with being outdoors in a cabin/cottage. I might dig up some plants, or move the hammock around, but whether I get (literally) dirty is just down to whatever random things I've done that day!

"Hey <smartwatch>, set a timer for 12 minutes" doesn't sound very exhausting.
If it's 90 degrees Celcius, I don't think you could sit there for an hour. If it's 90 american degrees, what kind of sauna is that?
I don't know about you guys but if I started timing my sauna visits, I would get MORE stressed out.
It probably just comes from tweaking the routine. Maybe they started out at 15 minutes in the sauna and 5 minutes in the cold plunge, but found they were getting too hot in the sauna and too cold in the cold plunge.
Sounds like typical geek stuff you see on any enthousiast forum. You should check the coffee forums.

You don't take your watch into the sauna! It's way too hot! I use a plain mechanical kitchen timer (outside the sauna). I've seen hourglasses that are designed to withstand the heat inside the sauna, but they're obviously not configurable to various increments.
More seriously: apparently studies show that using a Finnish (dry) sauna 5-7 times a week is good for longevity. You don't have to use them that way, but if that's your goal, it probably makes sense to fit it into your routine, and it's tough to do that without planning how long it will take.
