If you are referring to the internal temperature of the human body, studies show most bodies can only survive up to 108 degrees Fahrenheit, or 42 degrees Celcius, as the proteins inside the body begin to die at around 105F.
Cause is Key. A body temperature that is between 90F and 95F is not dangerous in and of itself. In other words, mild hypothermia or a low body temperature will not cause organs to fail or shut down. What is more important is the cause of the low body temperature, which may or may not be dangerous.
