And that was enough.

The Threshold That Nobody Can Find

In the study of hypothermia survival, one of the most important and most frustrating questions is: where is the line?

At what temperature, maintained for what duration, does severe hypothermia become definitively unsurvivable?

At what combination of core temperature, exposure duration, and peripheral damage does the outcome become inevitable regardless of treatment?

Medical researchers and emergency physicians have been trying to answer this question for decades, and the honest answer is that no definitive line has been found.

Cases of survival from seemingly impossible degrees of hypothermia keep appearing in the literature, pushing the apparent boundaries of what is survivable further and further.
