Could there still be enogh cooler blood in his extremities?<<< "Afterdrop" is sort of a lay term for something that is actually far more complicated than cold water from the extremities invading the core due to exercise. Hypothermia causes chemical changes that mess up the bodies electrolyte balances (and other things) and this can result in a much greater likelihood of cardiac arrest (especially upon exertion). Chemical reactions in the body don't work the same at low temperatures as they do at normal body temperatures and this results in a cascade of changes to body chemistry. Anyone who has gotten seriously hypothermic should not be moved much an gotten medical attention ASAP so they can be treated by professionals if complications arise before the bodies chemical balances can be restored.
