I guess this is why rich ghouls and professional athletes are into cryotherapy for anti-aging. Like that weird billionaire who also stole blood from his son. What's the consensus on that, is it a grift or do serious scientists think you can really extend your life by regularly locking yourself in a cold chamber or dunking yourself in an ice bath for a few minutes every day?
I have no serious knowledge about it, but for the thermic aspect I can't imagine it working in any way.
Your body will try its best to keep its core temperature constant. So you won't really cool your cells down.
In this process it will burn even more fuel to produce heat, so quite the opposide they want to archive.
