What causes death from freezing? Is it because it throws off our homeostasis?

When you’re core temperature drops, this causes your organs not to function properly, reduced blood flow to important organs, etc. you’re body literally can not function properly if it gets too cold. When you put you’re body into a shock like that you’re greatly increasing the chance of organ failure.

freezing the body freezes the water inside of cells.

if you’ve ever put a soda in the freezer too long and had it burst; that’s what happens to your cells when you freeze your body.

Our body is a big pile of chemical reactions. Every cell, every organ, is hosting innumerable reactions dedicated to keeping us alive.

Nearly all of those reactions are temperature dependent, or contain enzymes or other molecular machines whose functions are temperature dependent. What this means is that if the body temperature falls out of a certain range, those reactions start to shut down.

Hypothermia by definition is our core body temperature falling outside the lower end of our normal body temperature range. As this occurs, our body diverts blood from our extremities to our core organs in order to keep them warm and those critical life-sustaining reactions running.

However, as we continue to lose body heat to the environment, our temperature continues to fall and those reactions spool down, gradually causing multiple organ dysfunction and eventually death.
