What is the hottest temperature humans can survive?

Question

Not body temperature- I know a fever starts to get dangerous around 106... but I'm wondering, if someone was placed in a room with a thermostat, how high can the temperature go before their body begins to shut down?

Answer 1

That would depend upon the time of exposure, water intake, humidity, and the person's individual ability to acclimate to the temperature, body mass, etc.  How long does it take to raise the body's core temperature.  Just too many variables.

Answer 2

its about 52 degrees Celcius max above which our body cells will get burnt .  

Answer 3

a body temperature of 41ºC (106ºF) or higher -

seizures

headache

rapid pulse

unconsciousness
