Fenix6 @ Sauna / Spa / Wellness

Hello,

Let's begin: Are there concerns weiring the Fenix6 in a Sauna or Hamam?

I do not find any information about the max temperatures supported. So is it risky for the heath of my watch?

Are there cheaper Garmin watches which I should use and where I bother less when they break?

In fact I really like the feature "Body Battery" and I'd like to use it during wellness days where I suppose it should give me feedback about "recovering" or "draining" my personal battery. I have no idea how good this shall work by the way ;)

I would not be able to let a 600€ watch at the outside ot the sauna just waiting that me or someone else will walk away with it ;)
