There has to be a trick to cooling something fast enough then freezing it. People falling into freezing water, dying, then being revived ours later comes to mind. I do suppose actually freezing is very different but who knows, maybe there could be a connection?
- AstralStorm 3y agoThe body has time to prepare for the cold by making a lot of cryoprotectants in the cells. That of course only works in quite particular conditions and in a liivng host, and the induction would be quite painful. The remaining damage of defrost is fixed later on.

Except this doesn't exist, these people don't actually freeze, as in they never go bellow 0, most of them stay well above 0 actually. They're very different phenomenons For example: https://jmedicalcasereports.biomedcentral.com/articles/10.1186/s13256-019-2282-6 https://jmedicalcasereports.biomedcentral.com/articles/10.11... > A 52-year-old Italian mountaineer, was trapped in a crevasse and rescued approximately 7 hours later by a professional rescue team.... His core temperature was 26.0 °C or: https://en.wikipedia.org/wiki/Anna_Bågenholm https://en.wikipedia.org/wiki/Anna_Bågenholm > her body temperature decreased to 13.7 °C (56.7 °F), one of the lowest survived body temperatures ever recorded in a human with accidental hypothermia.
