It's not a joke. Cryotherapy is an alternative to ice baths or cold packs. It is that cold (below -100 degrees Celsius) and the players are in there for 2-4 minutes.
i can't imagine the pain that could cause. i've been in -90 f and it hurts the instant you step into that weather. -300 is insane. hope no one gets frostbite for staying in there an extra 10 seconds.

It's definitely possible. One of my physics instructors in college put his hand in liquid nitrogen in front of the class. Just for a few seconds though. He explained that there's a bit of a barrier that is formed so it would cause harm until the cold started to penetrate into the body more. I thought 2-4 minutes would be past that threshold but apparently not.
It's proven to be extremely effective according to every single marketing pamphlet I've ever come across.
There are a couple version of this- full body and neck-down. Full body is more of a freezer you walk in to. I think they only allow 2-3 minutes max at a time, and you'll have to work up to that. 30-60 seconds for a first timer is likely.
I know they initially used these for medical treatments but what for idr, but you have to be careful i did read about a girl who froze to death in one of these a few years back.
