Do you understand the boiling point of water, its 100 degrees celsius

And lets keep in mind how every liquid gram of water requires 540 calories to convert to steam, therefore, the both exist at the same temperature BUT steam has a lot more heat energy. Basic physics.

You obviously didn't visit many spas in your life, since the 60 degrees is nowhere near the temperature of most real spas. 100 celsius is much closer, thus, the temperature of steam you intake in a spa is often higher than 60 degrees.

And yes, you can inhale the steam as long as you do it in moderation, if you gonna take too much steam like an idiot obviously you gonna burn your lungs.

Let me guess, you the type of guy that will visit a doctor in case of Corona contraction? :) that's fine, do as it suits you. I've been visiting spas for last 7 years of my life and did various steam therapies, I'll take a guess and say you don't have as much experience with it. Just opinion. Which is irrelevant to me btw, so I don't know why you sharing
