Doesn't change the fact that when the wet-bulb temperature (i.e. a combination of the air temperature and humidity) does not allow for evaporative cooling (aka sweating) to work any more. No matter what, you cannot survive such conditions for a prolonged amount of time, as your body will slowly cook itself.

You can survive heat on its own in dry air (that's how people have thrived across MENA deserts, or how people survive saunas), you can survive extensive moisture (that's how people and plants have thrived in the rainforests). But you physically cannot survive in a wet-bulb temperature of > 35 °C for prolonged times.
