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.
I'm not sure but I believe once an external temperature above 212 degrees is reached a human will begin to die because of their internal fluids simply starting to boil, remember we are 70-90% water.. The coldest temperature your body can get before shutting down and going into hypothermic shock is 89 degrees.
