Those whose body temps have fallen to 32 degrees Fahrenheit have been in fact been resuscitated--there are a number of documented cases, even though cryonics (the process of freezing a body at death to be later revived) is not consistently possible.
Cryonics is the term used that refers to freezing the body over (usually) long time periods for possible resuscitation in the future.
The biological basis of cryonics has its roots in the fact that when the body temp is cooled, it slows metabolism, even to the point of heartbeat cessation and the need of non-functioning tissue for oxygen/nutrients. Blood then ceases to be circulated to tissue, but the tissue is also in a state of suspension and requires no nutrients because function has ceased. However, it has been proven that within a certain time period and under controlled condition, tissue (even brain tissue/cells) can be resuscitated after a certain point of blood and oxygen deprivation by a gradual warming of the blood and core temperature of the body, through resuscitation of the heart. The length of time in which this can be done is certainly limited, but it has been done successfully in a variety of cases.
